Software Development Outsourcing: Models, Costs and How to Choose a Partner

Updated October 2026 · Written and maintained by the Progression Agency strategy team

Software development outsourcing is hiring an outside company to design, build, test or maintain software that your business will own, under a contract that fixes the scope, the price model and who holds the code. It suits owners, operations leads and product teams who need engineering capacity or skills they do not employ, and it produces working software, documentation and a codebase another team could pick up. Progression Agency is based in New York City and works with clients across the United States and worldwide.

The short answerDecide what to keep in-house first: product decisions, account ownership and the knowledge of how your business runs. Then buy the engineering in the shape that fits the work: a fixed-scope project for a defined first release, time and materials for work that will change, a dedicated team for a product that never stops, or individual engineers who join your own team. Judge vendors on evidence you can inspect, such as a repository, a release history and named people, not on a day rate. Put intellectual property assignment, account ownership, acceptance criteria and an exit plan in writing before the first sprint, and measure delivery with working software every couple of weeks.

What is software development outsourcing?

It is paying a company outside your payroll to deliver software work under a contract, while your business keeps ownership of the result. The vendor supplies people, process and tools; you supply the goals, the decisions and access to your systems.

What outsourced software development covers

Outsourced software development spans far more than one app. Businesses hand outside teams customer portals, internal operations tools, software products sold by subscription, integrations between a CRM, an ERP and a payment processor, automated testing, cloud infrastructure and the slow, steady work of keeping an older system alive. Some buy a single module; others buy the whole product, from discovery to support. The same contract questions apply to all of it: who decides, who owns and who answers when something breaks.

Web: Customer-facing platforms. Portals, booking, ordering, accounts.
Ops: Internal tools. Dashboards, approvals, scheduling.
SaaS: Products you sell. Multi-tenant apps with billing.
API: Integrations. CRM, ERP, payments, data sync.
QA: Testing and quality. Automated suites, test plans.
Cloud: DevOps and hosting. Pipelines, monitoring, upkeep.

Three purchases that share one name

The phrase covers three different arrangements. In project outsourcing the vendor owns delivery of an agreed result. In a dedicated team the vendor supplies a stable unit that works only on your product. In staff augmentation individual engineers join your team and take direction from your managers. They carry different risks and suit different moments, which is why the models section below compares them side by side. If you already know you want engineers inside your own team, our dedicated developers page covers that staffing model in detail.

Where mobile apps and agency resale fit

This page is the umbrella view for software in general. Mobile products raise extra questions about app store accounts and store review rules, which our app development outsourcing page handles. Agencies that resell development under their own brand work through the arrangements on our white label web development page. And if you simply want to see what we build and how, start with our software development company page.

The industry behind the term

Federal statistics on the firms that do software work for others show its scale. The Bureau of Labor Statistics counts about 2.36 million people employed in computer systems design and related services in its preliminary September 2026 estimate, and about 1.06 million of them in custom computer programming services in August 2026. Those are the companies that write, test and support software to a particular customer’s needs, which is what a software development outsourcing company sells.

Why do companies outsource software development?

Mostly to get skills and capacity faster than they could hire them, and to avoid building an engineering department around work that has a beginning and an end. A delivery process that already works is the third reason, and an underrated one.

Skills a small team cannot hire for one project

A modest web platform needs product thinking, interface design, front-end and back-end engineering, database work, security, testing and cloud operations. Few businesses can justify a full-time hire for each, and the pay for those roles is high. In the BLS wage estimates for 2025, the median software developer earned $135,980 a year, the median information security analyst $129,180 and the median software quality assurance analyst or tester $104,300.

A small product team needs most of these skills at some point; outsourcing buys them for the months they are needed. Figures are medians before benefits, from the BLS public API, read October 14, 2026.

Capacity for a deadline

A regulatory change, a contract with a large customer or a system that is about to lose vendor support can create a year of work for a team sized for maintenance. Hiring for the peak leaves people idle afterward; an outside team can scale up for the push and back down when it ends, provided the contract allows it.

A delivery process that already works

Building software well depends on habits that take years to form: written requirements, code review, automated tests, release notes, a way to roll back a bad deployment. An established vendor brings those habits on day one. A company hiring its first engineers has to invent them, often after the first painful release. Our guide to the software development life cycle walks through each stage.

Attention on the business, not on running engineering

Managing engineers is its own discipline, with recruiting, career paths, on-call schedules and tooling budgets. For a company whose product is not software, outsourcing lets leadership spend its time on customers and operations while still getting systems built to its own specification.

In house vs outsource software development: how to decide

Hire when the software is the product and the work will never end; outsource when the work is bounded, specialized or urgent; combine the two when you need both continuity and range. The salary comparison alone points the wrong way, so price the loaded cost.

The loaded cost of one in-house engineer

On average, wages are about seven tenths of what a private employer spends on a worker. In the BLS Employer Costs for Employee Compensation series for June 2026, wages and salaries were 70.0 percent of private-industry compensation costs and benefits 30.0 percent. A software developer paid the 2025 median of $135,980 would, at that average mix, carry roughly $194,000 of total compensation cost a year before recruiting fees, equipment, software licenses and the manager’s time. That is arithmetic on averages, not a quote, but it is the right number to set beside a vendor’s monthly invoice.

When does in-house development win?

Keep engineering inside when the software is what customers pay for, when it changes every week in response to what you learn, and when the knowledge in it is your competitive edge. A software company that outsources its core product indefinitely ends up paying a vendor to hold the knowledge it most needs to own.

When does outsourcing win?

Outsource when the work has a defined end, needs skills you will use rarely, or must start before you could recruit. Integrations, migrations, a first release to test an idea, an internal tool and a security remediation project all fit. So does maintenance of a stable system that no longer justifies a full-time engineer.

A hybrid that suits growing companies

One pattern that works is a technical owner on staff, a product manager or a technical lead, with an outside team doing most of the building. The owner sets priorities, reviews pull requests and keeps the vendor honest; the vendor supplies the range of skills. Over time some companies hire engineers around that owner and keep the vendor for specialist work or peaks.

When to outsource software development, and when not to

Outsource work you can describe and verify; keep work that depends on judgment only your own people have. The test is whether an outsider, given a good brief, could tell when the job is done.

Work that outsources well

Projects with clear inputs and outputs are the safest place to start: connecting two systems through their APIs, rebuilding a portal on a modern framework, adding automated tests to an untested codebase, moving hosting to a managed cloud service, or building an internal tool your staff have described in detail. Each produces something you can test against written acceptance criteria. Our API development and DevOps services pages cover two of the most common examples.

Work to keep inside

Product strategy, pricing logic, the rules that encode how you serve customers and anything a regulator expects you to understand yourself should stay with your staff, even if a vendor writes the code. You can outsource the typing; you cannot outsource the accountability. If nobody inside can review what the vendor builds, hire or contract that reviewer before you outsource the build.

Why not to outsource software development

The honest objections are real. Communication across companies is slower than across a desk. Knowledge can leave when the contract ends. Quality varies from one engineer to the next, and you rarely choose who is assigned. Security exposure grows with every outside account that touches your systems. None of these is a reason to never outsource, but each needs a control in the contract or the process, and the sections below set them out.

Why some organizations move development back in house

Companies bring development inside when software becomes central to how they compete, when the coordination cost of a vendor starts to exceed the cost of employees, or when they realize the vendor holds knowledge they cannot replace. A planned exit is a sign of a healthy arrangement, not a failed one, and it only works if documentation, repositories and accounts were in your name from the start.

Software development outsourcing models compared

There are four buying models plus a run-and-maintain option, and the right one depends on how settled the scope is and how much direction you can give. Pick the model after a discovery phase, not before.

Project-based outsourcing at a fixed price

The vendor commits to a defined result for an agreed price. It works when requirements are stable and testable, such as a well-specified integration or a first release with a short feature list. The price includes the vendor’s allowance for risk, and every change becomes a priced change request, so a fixed price on a vague scope tends to end in arguments rather than savings.

Time and materials

You pay for the hours actually worked, usually against a capped monthly budget and a prioritized backlog. It suits products that will change as you learn, and it keeps the vendor’s incentives honest only if someone on your side reviews progress every sprint. Without that review, time and materials becomes an open tab.

A dedicated team for continuous product work

The vendor assembles a stable unit, often a lead engineer, two or three developers, a tester and a part-time designer, that works only on your product month after month. Knowledge accumulates in the same people, which is the closest outsourced equivalent to an internal team. You still set priorities; the vendor handles hiring, replacement and day-to-day management of those people.

Staff augmentation to fill a gap

Individual engineers join your existing team, use your tools and take direction from your managers. It suits companies with engineering leadership in place that need a specialist or extra hands. Because you direct the work, you carry more of the delivery risk than in a project or a dedicated team.

Managed services for systems already in production

Once a system is stable, some businesses buy a monthly service that covers monitoring, security patches, small fixes and a set number of hours for improvements. The contract should state response times by severity and what happens to requests that exceed the allowance.

Onshore, nearshore or offshore: where should the team sit?

Location trades hourly rate against shared working hours, legal reach and the cost of your own time spent coordinating. For a US business, the number of overlapping office hours is the most practical way to compare regions.

Overlap shifts twice a year because the US, Europe, Brazil and Mexico follow different daylight saving rules or none. Calculated with the IANA tz database for January 14 and July 15, 2026.

Onshore teams in the United States

Onshore vendors share your legal system, your business hours give or take three time zones, and your customers’ expectations about privacy and accessibility. Rates are highest, but so is the speed of a question answered the same morning. Contracts are enforceable in a court you know, which matters most when a dispute arrives.

Nearshore software development outsourcing

Nearshore usually means Latin America for a US buyer. As the chart shows, Bogotá and Mexico City share most of a New York working day, and São Paulo shares six or seven hours depending on the season. That overlap makes daily stand-ups and same-day code review practical. Ask how many of the team’s hours actually overlap with yours; some nearshore vendors staff from several countries.

Offshore software development outsourcing

Offshore teams in South and Southeast Asia share no hours of a 9-to-5 New York day, and teams in Central and Eastern Europe share up to two, depending on the city and the season, so either someone shifts hours or the work runs on written handoffs overnight. That suits well-specified modules, testing and maintenance with clear tickets. It struggles with discovery, ambiguous requirements and anything that needs a quick conversation, and it puts more weight on the quality of your written specifications.

Best countries to outsource software development: better questions than a ranking

Lists that rank countries tend to skip the factors that decide whether your project works. Ask instead: how many overlapping hours the specific team will keep, whether the people you met in sales are the people who will write the code, which law governs the contract and where you could enforce it, whether personal data will leave the country, and whether your code includes anything subject to export controls. A strong team in a weaker-ranked country beats a weak team in a top-ranked one.

How much does it cost to outsource software development?

It depends far more on the scope and the model than on the hourly rate. As published US price bands, a focused integration runs about $15,000 to $50,000, a client portal or business platform about $75,000 to $250,000, and a dedicated full-stack squad of three or four people about $30,000 to $55,000 a month. Every figure below is a market figure, and a quote follows a written scope.

A first release of a SaaS product3-6 months$60,000-$150,000
An enterprise system or a modernization6-12+ months$250,000+

Bands for dedicated developers and squads

Monthly engagements are priced per person. The published US bands on our dedicated developer page are $8,000 to $13,000 a month for a mid-level developer, $12,000 to $18,000 for a senior developer and $30,000 to $55,000 for a full-stack squad of three or four, each on a monthly term with a one-month notice period. Those are market figures, not a Progression rate card.

Why the hourly rate is the wrong number to compare

Two vendors quoting $45 and $150 an hour can deliver the same feature for similar totals once rework, management time and testing are counted. The cheaper hour often comes with thinner specifications, less senior review and more of your own staff’s time spent explaining and re-checking. Compare quotes on the total cost of a defined first release, including what you will spend inside your own company to manage it.

Software development outsourcing prices: what moves a quote

The drivers are the number of distinct user roles, the number of systems to integrate, data migration from older tools, compliance requirements, performance and availability targets, and how much design work is needed before engineering. A quote that does not ask about each of these is a guess. Our software development company page lists the same bands.

Costs that never appear on the vendor’s invoice

Budget separately for cloud hosting and third-party services, which should be billed to your own accounts; independent security testing if customers or regulators expect it; your staff’s time for reviews, demos and acceptance testing; and the first year of maintenance after launch. A system that cost $120,000 to build will still need care every month it runs.

How to outsource software development, step by step

Write down the problem, pay for a short discovery phase, choose the model from what discovery finds, start with a release you can test, and keep ownership and review inside your company throughout. The flow below is the order that avoids the most expensive mistakes.

Flowchart of how to outsource software development: write a brief, name an internal owner, shortlist vendors on evidence, buy a paid discovery phase, choose the model and sign, ship a first release, then review and decide.Flowchart of how to outsource software development: write a brief, name an internal owner, shortlist vendors on evidence, buy a paid discovery phase, choose the model and sign, ship a first release, then review and decide.
The order matters more than any single step: discovery before the model, ownership before the first commit.

Write the brief before you speak to vendors

One page is enough: what problem the software solves, who uses it, which systems it touches, what must be true at launch, the date that matters and the budget range you can defend. Vendors who receive the same brief give quotes you can compare. Vendors who write the brief for you will write one that suits their strengths.

Run a paid discovery phase

A short, paid discovery of a few weeks, where the vendor interviews your users, maps the data and proposes an architecture, is cheap insurance. It produces documents you own whether or not you continue with that vendor, and it turns a vague estimate into one with named assumptions. Our software consulting page describes this kind of assessment.

Start with a release you can test

Ask for the smallest version that real users can try, delivered in short iterations with a demonstration at the end of each. Teams working in an agile rhythm show you working software rather than status reports, which is one of the best early warnings that a project is drifting.

How to outsource custom software development without losing control

Control comes from three things you keep: the decision rights over scope, the accounts where the code and data live, and the acceptance tests that say when work is done. Hand everything else to the vendor. If you are still deciding whether custom work is justified at all, our comparison of custom software and off-the-shelf tools sets out the trade-offs.

The software development outsourcing contract: clauses that protect you

The contract decides who owns the code, what counts as done, how changes are priced and how you leave. Have counsel review it; nothing here is legal advice, but these are the clauses worth asking about by name.

Intellectual property assignment, in a signed writing

A work-for-hire label alone may not give you the code. Under 17 U.S.C. 101, a work made for hire is either made by an employee within the scope of employment or a commissioned work in one of nine listed categories with a signed written agreement, and software is not named among those categories. When a vendor’s employees write your code, 17 U.S.C. 201(b) makes the vendor, as their employer, the author. An express written assignment is the route most contracts use: 17 U.S.C. 204 says a transfer of copyright ownership is not valid unless it is in writing and signed by the owner of the rights or its authorized agent. Ask for assignment of all code, designs and documentation on payment, covering subcontractors too.

Open-source components and a bill of materials

Modern codebases routinely include open-source libraries, each with its own license terms. The contract should require the vendor to list them, avoid licenses you have ruled out and deliver a software bill of materials, which CISA describes as a nested inventory of the components that make up software. CISA’s page also lists 2026 updates to the minimum elements for an SBOM.

Acceptance criteria and a warranty period

Define done before work starts: the tests a feature must pass, the browsers and devices it must support, the performance it must reach. Then agree a warranty period after acceptance during which the vendor fixes defects at its own cost. Without written criteria, acceptance becomes a matter of opinion, and opinions get expensive at the end of a fixed-price project.

Change control

Every project changes. The contract should say how a change is requested, how the vendor estimates its cost and time, who can approve it, and how approved changes appear in the next invoice. A short written change log protects both sides from the slow drift that turns a fixed price into a dispute.

Do you need source code escrow?

Escrow places a copy of source code with a third party, to be released to you if the vendor fails. It matters when the vendor hosts and owns the software you rely on. If the repository already sits in your own organization, as it should for custom work, escrow adds little; insist on the repository instead.

Subcontractors, key people and non-solicitation

Require written approval before any part of the work is subcontracted, and the same confidentiality, security and IP terms for anyone who is. Name the key people the proposal relied on and agree what happens if they leave. If the vendor asks for a clause barring you from hiring its staff, make it time-limited and mutual where it can be.

Exit, handover and transition support

Write the end into the start. The exit clause should list what the vendor hands over, which includes source code, build scripts, infrastructure definitions, credentials it created, documentation and open tickets, and should commit it to a number of hours of transition support at agreed rates. A vendor confident in its work will agree to this easily.

Accounts and access: what stays in your company’s name

Everything the software needs to run should be owned by your company and shared with the vendor through roles you can revoke. Ownership decides whether you can change vendors in a week or in a quarter.

Check grid of ownership in outsourced software development: your company owns the repository organization, cloud accounts, domains and app store accounts, and production data, and approves releases; the vendor writes and reviews code, runs tests and deployments and documents decisions; both review delivery each sprint.Check grid of ownership in outsourced software development: your company owns the repository organization, cloud accounts, domains and app store accounts, and production data, and approves releases; the vendor writes and reviews code, runs tests and deployments and documents decisions; both review delivery each sprint.
A starting split; regulated businesses may keep deployment approval and production access entirely inside.

Code repositories

Create the organization on your code host yourself and invite the vendor’s engineers into it. GitHub’s documentation on roles in an organization says organization owners have complete administrative access and recommends limiting the role to no fewer than two people, so name two owners inside your company. If a vendor has already started in its own account, GitHub’s guide to transferring a repository explains that issues, pull requests and the wiki move with it.

Review gates inside the repository

Repository settings can enforce the oversight a contract only describes. GitHub’s protected branches can require a set number of approving reviews before a pull request merges and can require status checks such as automated tests to pass first. Asking for one approval from your own technical owner on the main branch makes every change visible.

Cloud accounts

The cloud account that hosts production should be opened by your company, with billing on your card or invoice. Amazon Web Services’ guidance on root user best practices recommends not using the root user except for tasks that require it, protecting it with multi-factor authentication and creating an administrative user for everyday work. Give the vendor roles inside that account rather than letting it run your systems from its own.

Domains, third-party services and design files

Register domains to your company, put payment processors, email services, mapping and analytics keys in your name, and keep design files and architecture notes in tools you control. Each of these is small on its own; together they decide whether a transition takes a day or a month.

Repo: Source code repository. Your organization, two owners.
Cloud: Hosting accounts. Root user locked away, roles shared.
DNS: Domains and DNS. Registered to your company.
Data: Production data. Copies leave only as agreed.
Keys: Third-party services. Billing and API keys in your name.
Docs: Designs and decisions. In your wiki, not their drive.

Security and compliance in software engineering outsourcing

Outsourcing extends your security perimeter to another company’s laptops and accounts. Ask for evidence that matches your risk, and check which laws follow your data and your code to the vendor.

What does a SOC 2 report show?

A SOC 2 report covers an examination of controls at a service organization relevant to security, availability, processing integrity, confidentiality or privacy, under the framework the AICPA publishes for SOC 2. Ask which systems and services the report covers, because a report on the vendor’s hosting product may say nothing about how its engineers handle your source code.

Secure development practices

NIST’s Secure Software Development Framework (SP 800-218, version 1.1) sets out a core set of practices for reducing vulnerabilities in released software, and NIST notes that buyers can use its common vocabulary when talking to suppliers. For web applications, OWASP’s Application Security Verification Standard, whose latest stable version is 5.0.0, provides a basis for testing web application security controls and a list of requirements you can name in acceptance criteria. Ask a vendor which of these it follows and how it shows it.

Health data and HIPAA business associates

If the software will create, receive, maintain or transmit protected health information for a covered entity, the vendor is likely a business associate, and under the definition in 45 CFR 160.103 so is a subcontractor that does the same on the business associate’s behalf. That means business associate agreements down the chain. Our HIPAA compliant software development page covers the safeguards in detail.

Payment card data and PCI DSS

The PCI Data Security Standard applies to entities that store, process or transmit cardholder data or that could affect the security of the cardholder data environment. A vendor with access to that environment is part of your compliance picture. A design in which card numbers go straight to a payment processor’s hosted payment fields keeps them off your own servers; make that a written requirement.

Export controls when code is shared abroad

If your product contains export-controlled technology, sharing its source code with engineers overseas is an export, and under 15 CFR 734.13 releasing controlled technology or source code to a foreign person inside the United States is a deemed export to that person’s most recent country of citizenship or permanent residency. The Commerce Department’s deemed exports guidance explains the rule. Ask counsel whether your code is controlled before an offshore or mixed-nationality team touches it.

Individual contractors and worker classification

Hiring individual freelancers directly, rather than through a company, raises a tax question. The IRS guidance on independent contractors and employees sorts the evidence into behavioral control, financial control and the type of relationship, and says the whole relationship must be considered. A contractor who works only for you, on your schedule, with your equipment, may look like an employee.

Give the team one decision-maker, a fixed rhythm of demonstrations and reviews, and a handful of delivery measures you look at every month. Oversight, more than talent, is what an outsourcing relationship depends on.

One accountable owner on each side

Name one person in your company who sets priorities and accepts work, and ask the vendor to name one who answers for delivery. Decisions that wait for a committee stall a team that is paid by the hour; decisions made by whoever happens to be on the call contradict each other by the next sprint.

A rhythm of demos, backlog reviews and steering

Every sprint should end with a demonstration of working software in an environment you can use yourself. A short backlog review agrees the next priorities. Once a quarter, a steering meeting looks at budget, risks and whether the model still fits. Write the decisions down; memory is not a project record.

Delivery metrics worth tracking

DORA’s software delivery metrics are a well-documented starting point. DORA now uses five: change lead time, deployment frequency, failed deployment recovery time, change fail rate and deployment rework rate, grouped into throughput and instability. They show whether changes reach production steadily and safely, which is what you are paying for. Track them as trends for the same team, not as targets to compare with other companies.

Quality gates that run without you

Automated tests on every pull request, required code review, dependency and secret scanning, and a staging environment that matches production catch many problems before you see them. Ask the vendor to show these running in your repository during the first month.

Measures for an outsourced software development team
MeasureWhat it tells youWhat to watch for
Working software demonstrated each sprintReal progress, not reported progressSeveral sprints of slides and no demo
Change lead timeHow long a committed change takes to reach productionA steady rise as the codebase grows
Deployment frequencyWhether releases are small and routineBig, rare releases that need a weekend
Change fail rateHow often a release needs immediate repairRepeated hotfixes after releases
Escaped defectsBugs found by users rather than testsThe same defect returning
Budget burn against the backlogWhether spend matches delivered scopeHours rising while finished work stalls

How to choose a software development outsourcing company

Choose on evidence you can inspect: code, release history, the named people who would do the work and how they handled a project that went wrong. Ask every candidate the same questions and compare the answers in writing.

Software development outsourcing companies compared on evidence, not lists

Roundups of top software outsourcing companies are a place to find names, not a way to choose between them. Some are compiled by directories or by vendors themselves, and none can tell you whether a team suits your project. Treat a list as a longlist, then shortlist three software development outsourcing companies whose recent work resembles yours and test them against the requirements below.

Questions to put to every candidate

Ask each shortlisted vendor the same questions, in writing, and compare the answers side by side:

  • Who exactly will work on our project, and can we meet them before signing?
  • Where will our code live, and who will own the organization it sits in?
  • What does your definition of done include?
  • Can we see a pull request with its review comments and a release note from the last month?
  • How many hours of your engineers’ day overlap with ours?
  • Which project went over budget, and what did you change afterward?
  • What will you hand over if we part ways?

Run a paid pilot before the big contract

A paid pilot of a few weeks on a real but contained piece of work tells you more than any proposal. Agree its scope, acceptance tests and price in advance, and judge it on the code, the communication and how the team handled the first disagreement.

What a custom software outsourcing company should refuse to do

A good vendor will refuse to quote a fixed price on a one-line brief, refuse to start without access to your systems in your name, and refuse to promise a deadline that its own estimate does not support. Refusals like these are evidence of a process.

Price: A fixed price with no discovery. Someone is guessing the scope.
Access: No repository access until launch. You cannot see what you pay for.
People: Team names withheld. Subcontracting you cannot check.
Tests: No automated tests in the plan. Every change gets riskier.
Exit: Handover fees in the fine print. Leaving becomes a negotiation.
Rate: A day rate quoted before a brief. The cheapest number, not the cost.

Our software development company page lists the questions to ask a vendor about its own build process; the list above is about the outsourcing relationship itself.

Outsourced software development for small firms, startups and regulated businesses

The same principles apply at every size, but the first risk differs: for small firms it is building too much, for startups it is losing the code’s knowledge, and for regulated businesses it is a vendor outside the compliance boundary.

Small businesses

A business of a few people should usually try to buy, configure or connect existing tools before commissioning anything custom, and should outsource only the piece that is truly its own. Our small business software development guide works through that order.

Startups

Founders without a technical co-founder who outsource the first version later face investors who ask who understands the code. Keep a technical advisor or fractional lead on your side, own the repository, and plan the handover to your first hires. Our page on software development for startups covers funding stages and due diligence.

Healthcare, finance and other regulated sectors

Regulated businesses should write their compliance duties into the vendor contract before access is granted: agreements for health data, payment-card scope, record retention and audit rights. Our healthcare software development and fintech software development pages describe the sector rules.

Enterprises with existing engineering

Large organizations can outsource specific capabilities, such as a modernization program, a data platform or overflow capacity, alongside internal teams. The integration with internal standards, security reviews and release processes is the work. Our enterprise application development page covers that environment.

Plan for questions about how software is built, not only what it does, even on a small project. Four developments make them more likely.

Evidence of secure development

Larger customers’ security reviews can ask how code is written, reviewed and released, not only how servers are protected. A vendor that can map its process to NIST’s framework or to OWASP’s verification standard answers those questions for you when your own customers ask.

Software bills of materials

Component inventories are the subject of active federal guidance: CISA’s page lists 2026 updates to the minimum elements for an SBOM. Asking for one at each release costs a vendor little when its build tooling can generate it.

AI coding assistants inside vendor teams

Engineering teams can now draft code with AI assistants. That changes nothing about ownership or quality obligations, but it is worth asking which tools the vendor uses, whether your code or data is sent to them, and how generated code is reviewed before it merges. Put the answers in the security section of the contract.

Delivery metrics that keep evolving

DORA’s research moved from four metrics to five and replaced mean time to recover with failed deployment recovery time. Agree the definitions you will use at the start of an engagement, so the numbers you review in month twelve mean what they meant in month one.

Who do AI assistants name when buyers ask for a software partner?

Buyers can ask ChatGPT, Claude, Perplexity, Gemini, Microsoft Copilot or Google’s AI Overviews for a shortlist of software development outsourcing services before they visit a single vendor site. Pages that state plainly what a company builds, where it works and how it engages give those answers something to cite.

How buyers phrase the question

Prompts can be specific: a software outsourcing company in the USA that builds healthcare portals, a nearshore team that works Eastern time, a firm that will take over an existing codebase. Pages that answer those specifics in plain words give an assistant something to quote.

What assistants tend to draw on

Pages that state plainly what a company builds, where it works and how it engages are easier for an assistant to quote. Google says its AI Overviews and AI Mode have no additional requirements beyond being indexed and eligible to show with a snippet, so the basics of being findable still apply.

What a vendor should publish to be named

Clear pages for each service and model, the locations and hours it works, the industries it builds for, the questions it asks before quoting and the terms it offers on ownership and exit. Specific, checkable statements are easier for an assistant to quote than adjectives. Our answer engine optimization work starts from that principle.

Using an AI shortlist sensibly

Treat an assistant’s list as a starting point. Check each name against the vendor’s own site, its recent work and the requirements table above, and ask the assistant for the source of any claim that matters to your decision.

How Progression approaches outsourced software development

We are a US-based partner in New York City, working in our clients’ business hours with code and accounts in the client’s name. One team covers discovery through support, and the scope is written down before we build.

What we commit to in writing

Before any code, you get a written scope and an estimate. During the build, you see working software every two weeks, each time with a brief written note. From the first day, the code, the data and the cloud accounts belong to your company. And we choose mainstream technology, so a future team can be hired to maintain it.

Project teams and dedicated developers

For defined builds we work as a project team across discovery, design, engineering, testing and support. For teams that need capacity inside their own process, our dedicated developers work on monthly engagements with a notice period, start with a two-week paid trial, sign confidentiality agreements before onboarding and work under your security policies with least-privilege access.

Where the onshore model fits best

What we offer is the onshore version: US hours, US contracts and one accountable team in New York City. When shared working hours and one accountable team matter more than the lowest hourly rate, that is the version to choose.

These pages go deeper on each part of an outsourced build, from the service itself to the models and the rules.

Frequently asked questions

In plain terms, what does software development outsourcing mean?
It means hiring an outside company to design, build, test or maintain software your business will own. The vendor supplies engineers, process and tools under a contract; you keep the goals, the decisions, the accounts where code and data live, and the right to take the work elsewhere.
What kinds of work does outsourced software development cover?
Customer portals, internal tools, subscription software products, integrations between business systems, automated testing, cloud and DevOps work, and maintenance of systems already in production. A vendor can take a single module or a whole product from discovery to support.
Why do companies outsource software development instead of hiring?
To get a full range of skills quickly without building an engineering department for bounded work. The BLS median wage for a software developer was $135,980 in 2025 before benefits, and a small product also needs design, testing, security and cloud skills that one hire rarely covers.
What are the strongest reasons not to outsource software development?
Slower communication across companies, knowledge that can leave when the contract ends, uneven quality between engineers and more accounts with access to your systems. Each needs a control: an internal owner, documentation in your tools, code review rules and access you can revoke.
Can a company outsource software development and keep control of the product?
Yes, if it keeps three things: decision rights over scope, ownership of the repository and cloud accounts, and written acceptance tests. With those in place a vendor can do the engineering while the company decides what gets built and when it is done.
How do you outsource software development effectively?
Write a one-page brief, name one internal owner, shortlist vendors on inspectable evidence, buy a short paid discovery phase, choose the model from what discovery finds, sign IP and exit terms, then ship a first release in small increments with a demo every sprint.
What does outsourcing software development typically cost?
As published US price bands, an integration runs about $15,000 to $50,000, an internal tool $25,000 to $75,000, a client portal $75,000 to $250,000 and a SaaS first release $60,000 to $150,000. Hourly bands range from $20-$60 offshore to $100-$250 for a US agency. These are market figures; a quote follows a written scope.
At what point does outsourcing software development make sense?
When the work has a clear end, needs skills you will use rarely, or must start before you could recruit. Integrations, migrations, internal tools, first releases and maintenance of stable systems fit well. Keep work in-house when the software is your core product and changes every week.
Why are some organizations moving software development back in house?
Usually because software has become central to how they compete, because vendor coordination costs have grown, or because they realize the vendor holds knowledge they need. The move goes smoothly only when repositories, accounts and documentation were in the company’s name from the start.
How do you outsource custom software development safely?
Keep decision rights, accounts and acceptance tests inside, and hand the vendor the engineering. Start with paid discovery so the estimate rests on named assumptions, require an assignment of IP in a signed writing, and review working software at the end of every sprint.
How many companies outsource software development?
The closest federal measure is employment at the firms that do the work: BLS estimates about 2.36 million people in US computer systems design and related services in September 2026, about 1.06 million of them in custom computer programming services in August 2026.
How do onshore, nearshore and offshore software development outsourcing differ?
By rate, shared hours and legal reach. A US team shares your business day and courts. Bogotá or Mexico City shares six to eight hours of a New York day; Bengaluru and Manila share none without a shifted schedule. Published hourly bands fall as overlap falls.
Which outsourcing model suits a product whose scope keeps changing?
Time and materials with a capped monthly budget, or a dedicated team, both with a product owner on your side who reprioritizes every sprint. A fixed price fits only when the requirements are stable enough to test against; otherwise every change becomes a priced dispute.
Who owns the code that a software development outsourcing company writes?
Whoever the contract says, so get it in writing. Under 17 U.S.C. 204 a transfer of copyright ownership must be in a writing signed by the owner of the rights. Ask for assignment of all code, designs and documents on payment, including work by subcontractors, and have counsel review the clause.
Does a work made for hire clause give us the source code?
Not reliably. The statute defines a work made for hire as an employee’s work within the scope of employment or a commissioned work in nine listed categories with a signed agreement, and software is not named among them. An express written assignment is the commonly used route; have counsel review it.
What belongs in a software development outsourcing agreement?
IP assignment, accounts in your name, open-source rules with a component list, acceptance tests and a warranty period, a change control process, security and incident terms, approval of subcontractors, data location and deletion, and an exit clause with a handover list and transition hours.
Do we need source code escrow if the repository is ours?
Rarely. Escrow protects you when a vendor hosts and owns software you depend on. When the repository sits in your own organization and you control the cloud accounts, you already hold the code; spend the effort on documentation and build scripts instead.
What security evidence should an outsourced development team provide?
Its secure development practices, such as alignment with NIST’s SSDF or OWASP’s ASVS, its code review and dependency scanning rules, any controls report such as SOC 2 with a scope that covers engineering, and incident notification terms you can put in the contract.
Can a HIPAA covered entity outsource software development?
Yes. A vendor that creates, receives, maintains or transmits protected health information on your behalf is generally a business associate, and its subcontractors that do the same are too under 45 CFR 160.103. Business associate agreements are typically signed before access; counsel can confirm what applies.
How many hours of overlap do we need with an outsourced team?
For discovery-heavy work, aim for at least three or four shared hours a day so questions are answered the same day. Well-specified maintenance and testing can run on written handoffs with little overlap. Get the team’s committed overlap in writing, not the sales team’s.
Which delivery metrics show an outsourced team is performing?
Working software demonstrated every sprint, then DORA’s five measures: change lead time, deployment frequency, failed deployment recovery time, change fail rate and deployment rework rate. Track them as trends for the same team, alongside escaped defects and budget burn against the backlog.
How do we switch software outsourcing vendors without losing work?
Hold the repository, cloud accounts and documentation yourself, then invoke the exit clause: source code, build scripts, infrastructure definitions, credentials and open tickets handed over, with transition hours at agreed rates. Remove the old vendor’s access the day the new team takes over.
Are rankings of top software outsourcing companies reliable?
Treat them as longlists. Some are compiled by directories or vendors and cannot judge whether a team suits your project. Shortlist three firms whose recent work resembles yours, then compare code, named people, release history and exit terms.
Does Progression Agency offer software development outsourcing services?
Yes, as a US-based team in New York City working your business hours: project teams for defined builds and dedicated developers on monthly terms. Scopes and estimates are written before code, working software arrives every two weeks, and you own the code, data and cloud accounts from day one.
