We have a development department working across complexity levels — from straightforward builds to custom functionality and integrations with the software you already run.
Web development is what happens after design decides how a site should look: building the thing so it works, loads fast, and can be maintained by someone who is not the person who built it. This page covers what that involves and when you need development rather than design.
Development versus design — the distinction that decides your quote
| Web design | Web development | |
|---|---|---|
| Answers | How should it look and flow? | How does it actually work? |
| Typical output | Layout, visual system, content structure | Functioning site, integrations, data handling |
| You need it when | The site is pages and forms | The site has to do something |
| Cost driver | Number of unique layouts | Complexity of behaviour |
Most small business sites are a design job with light development. If someone quotes a large development budget for a brochure site, ask what is being developed. Conversely, if your site needs to calculate, integrate, sync, gate or transact, that is development and pricing it as design produces a quote that will not survive contact with the work.
What we build
- WordPress builds, including custom functionality where the platform stops short
- Integrations between your site and the software you already run — booking systems, CRMs, payment providers, inventory
- Custom forms and calculators that do real work rather than collecting an email
- Performance work: sites that load fast on a phone on mobile data, which is where most of your traffic is
- Fixes and rescue work on sites built by someone who has since disappeared
Built to be maintained
The most expensive websites are the ones nobody can safely change. A site built with clever shortcuts that only its author understands becomes a liability the moment that author is unavailable. Everything gets built so that a competent developer who has never seen it can pick it up — which is also what makes it safe for you to leave.
Speed of delivery
Most small business builds take about two days once decisions and content are in place. Genuine custom development takes longer, and the honest signal is that anyone quoting two days for a complex integration has not understood the requirement.
See our web design services for the design side, website maintenance services for keeping it healthy, and what a website costs for market numbers.
What it costs: Web Development Services
Website work is priced by the number of templates, the content that has to be produced and the systems that must connect, not by page count. For Web Development Services, the ranges below are the planning figures from our marketing agency pricing guide and website cost guide; a quote follows a written scope and a redirect map.
| Project | Small agency range | What drives the number |
|---|---|---|
| Brochure site, 5–12 pages | $8,000–$25,000 | Custom design versus template |
| Site plus content program | $20,000–$45,000 | The content is the half that makes it rank |
| Service business site, 20–60 pages | $18,000–$55,000 | Templates, integrations, content volume |
| Ecommerce, small catalog | $20,000–$70,000 | Integrations and SKU count |
| Redesign of an existing site | $9,000–$40,000 | Redirect map, content migration, platform change |
| Landing page, single | $1,200–$4,000 | Offer strategy more than design |
| Website maintenance | $150–$800 / month | Updates, backups, security, minor edits |
Ranges are US planning figures, not quotes. Every engagement is priced after a written scope, and the planning range tells you which tier the conversation starts in.

Custom web development, platforms and hosting
As a web development agency headquartered in New York City and working nationwide and worldwide, our web development services span custom-coded sites in Next.js and Astro, custom WordPress themes, Webflow builds and Shopify stores, and the hosting, security and maintenance that keep them running. Which route is right depends on who edits the site, what it must do and the budget; these guides explain how we decide.
Start with custom website development services for hand-built sites, web development frameworks for the front-end, back-end and full-stack options, and best CMS platforms or WordPress alternatives for the platform decision.
- React vs Vue vs Angular: the front-end framework comparison.
- Next.js vs React: when a plain React app is not enough.
- Astro vs Next.js: content sites versus web apps.
- Headless CMS vs traditional CMS: when to go headless.
- Webflow vs WordPress: the two platforms most business sites use.
- Web hosting types compared: shared, VPS, cloud, dedicated and managed.
- Vercel vs Netlify: hosting for Next.js and Astro sites.
- WordPress hosting guide: managed vs shared vs VPS.
- Website migration services: moving platform or host without losing rankings.
- Website speed optimization: Core Web Vitals fixes.
- Website security services: hardening, firewall and monitoring.
- Website development cost: planning ranges by site type.
When do you actually need custom web development?
When the site has to do something rather than say something. Marketing pages rarely justify custom development; portals, calculators, booking and quoting flows, and anything integrating with an internal system almost always do.
This matters commercially because custom code is the most expensive thing on a website and the most expensive thing to keep. Every custom component is something that must be maintained, tested after each dependency update, and understood by whoever inherits it. A site that is eighty percent standard templates and twenty percent custom application is cheap to run; a site that is custom throughout because the original team preferred building to configuring is a liability that grows.
The useful test is whether an off-the-shelf component would embarrass you in front of a customer. If not, use it.
What do custom web development services include?
Discovery and specification, front-end build, back-end and data, integrations, testing, deployment, and handover documentation. The last one is routinely dropped and is the one that determines what the work is worth in two years.
Specification
What it must do, in enough detail to be testable. Vague specifications are the single largest cause of overrun in this category.
Front-end
Templates and components, built to be reused. Building pages rather than templates is how a site becomes unmaintainable.
Back-end and data
Where the business logic lives. Worth more scrutiny than the visual layer, because it is harder to change later.
Integrations
CRM, payments, ERP, and anything internal. Usually the part that slips, because it depends on a system somebody else owns.
Testing and deployment
Including a staging environment. A project without one will have its testing done by customers.
Handover
Documentation, repository access, and a named person who can explain it. Get this in the contract rather than requesting it at the end.
Should you outsource web development, and what about white label?
Outsourcing web development services works when the specification is clear and the relationship is long enough for context to accumulate. It works badly for exploratory work where the requirements are still being discovered through building.
White label web development services — where an agency delivers under your brand — are common and legitimate. The two things to establish are who holds the code and who your client reaches when it breaks at nine on a Friday. Both should be written down before the first project, not after the first incident.
What does custom web development cost, and what drives the number?
Integration count and specification clarity drive cost far more than page count or stack choice. A well-specified project with two integrations is predictable; a vague one with six is not, at any price.
Regulated sectors cost more for reasons that are not technical. Healthcare web development carries privacy obligations that change how data is stored, logged and tracked — including the fact that ordinary analytics and advertising pixels can be a compliance problem on pages handling patient information. That constraint shapes the build and should be priced in at specification rather than discovered at launch.

Frequently asked questions
What are custom web development services?
Building the parts of a site that off-the-shelf themes and page builders cannot: integrations, applications, complex data handling and business logic.
When do I need custom development instead of a template?
When the site has to do something rather than say something. Marketing pages rarely justify it; portals, configurators and internal integrations almost always do.
How much do custom web development services cost?
Cost is driven by integration count and how clearly the requirements are specified, not by page count or stack choice. A vague specification is expensive at any price.
How long does custom web development take?
Weeks for a contained component, months for an application. The specification phase is where time is saved or lost.
What is white label web development?
An agency builds under your brand for your client. Establish who holds the code and who the client reaches when it breaks, in writing, before the first project.
Should I outsource web development?
It works well with a clear specification and a long enough relationship for context to accumulate. It works badly for exploratory work where requirements emerge through building.
What is full stack web development?
Front-end and back-end handled by the same team or person. It suits smaller projects; larger ones usually benefit from specialists on each side.
What do small businesses actually need?
Usually a well-configured standard build with one or two custom pieces. Web development services for small businesses go wrong most often by making too much of the site custom.
What is different about healthcare web development?
Privacy obligations change how data is stored, logged and tracked — including whether ordinary analytics and advertising pixels can run on pages handling patient information. That belongs in the specification, not the launch checklist.
Who owns the code at the end?
You should. Put repository access, documentation and a named contact in the contract rather than requesting them after handover.
Do I need a staging environment?
Yes. Without one, testing is done by your customers, and update failures happen in public.
What is the most common reason projects overrun?
An untestable specification, followed by integrations that depend on a system somebody else controls. Neither is a development problem.
