Updated October 2026 · Written and maintained by the Progression Agency strategy team
A CMS web development company designs the content model, editing screens and integrations behind a website so your team can publish, translate and update pages without filing a ticket, and builds or customizes the platform when an off-the-shelf setup falls short. We build on WordPress, Drupal, Webflow and Shopify, deliver headless builds with Next.js or Astro front ends, connect the CMS to your CRM and other systems, and move sites from one CMS to another with a redirect map so search traffic is protected. Tell us who publishes what, and we will recommend the platform and put the scope in writing before any code is written.

The short answerProgression builds sites on WordPress, Drupal, Webflow and Shopify, plus headless builds with Next.js or Astro, and designs the content model and editor workflow so non-developers can publish. Integrations and migrations are part of the work. Sites on a CMS start from $9,500 for a brochure site, while custom CMS, headless and integration builds are quoted after a written scope. Progression Agency is based in New York City and works with clients across the United States and worldwide.
Prices are Progression’s published fixed-scope website prices and one-off project prices; custom CMS, headless and integration builds are quoted after a written scope. Platform and standards details were read in October 2026. General information, not legal advice.
What does a CMS web development company do?
A CMS web development company sets up the system that lets non-developers manage a website, then builds the templates, rules and connections around it. When people search for a CMS development company, they usually want one team to own the whole chain from content model to launch.
What CMS development means
CMS development, or content management system web development, is the work of shaping a platform to fit how an organization publishes: the content model that defines types and fields, the editor screens, the templates that display content, the integrations that move data in and out, the migration of existing pages and the support after launch.
What is a CMS developer?
A CMS developer, sometimes called a content management system developer, builds and customizes the platform behind a site, not only the pages on it. The role covers content modeling, templates, plugins or modules, editor tools and integrations. Our CMS development services are the same job done as a team.
Do web developers use a CMS?
For most content sites, yes. A CMS saves building login, editing, permissions and publishing from scratch. Developers skip it when the product is an application rather than a content site, or when no platform fits the rules, in which case the build is closer to a web app.
CMS development services
Our CMS development services split into nine pieces, so a project can buy only the ones it needs. CMS web development services run from modeling a handful of page types to a full platform with integrations, and every piece is quoted after a written scope.
| Service | What it covers | When you need it |
|---|---|---|
| Content modeling | Types, fields, relationships, taxonomies and URL rules | Before any design, and whenever content gets more complex |
| Theme or front end | Templates, components and the visual layer | A new site, a redesign or a move to headless |
| Editor roles and workflow | Permissions, drafts, approvals and scheduling | More than a few people publish |
| Integrations | CRM, ERP, commerce, search, analytics and asset libraries | Data must flow between the site and other systems |
| Migration | Inventory, mapping, import, redirects and parity checks | You are leaving a platform |
| Performance and security hardening | Caching, updates, access rules and monitoring | Before launch and as a monthly habit |
| Accessibility | Accessible templates and authoring fields | Public-facing sites with legal or contractual duties |
| Hosting setup | Environments, deploys, backups and domains | A new build, or a move from weak hosting |
| Training and handover | Recorded sessions and a written guide | Every launch |
CMS website development services
CMS website development services produce a working site on a platform you can edit: model, theme, roles, content entry and launch. For marketing sites this is the usual starting point, and our fixed-scope rows, covered below, give a sense of scale.
CMS implementation services
CMS implementation services set up a chosen platform properly: environments, access rules, backups, caching, plugins or modules vetted before install, and editor accounts. Most trouble in later years traces back to a hurried implementation, so this is the step we slow down.
CMS customization services
CMS customization services extend an install you already have: new content types, custom fields, workflow steps, editor tools and small integrations. We read the existing code and configuration first, so changes fit the site instead of fighting it.
Content modeling: the decision that shapes everything else
Content modeling decides what a page is made of before anyone designs how it looks. A good model makes the editor screens obvious and the templates simple. A poor one forces editors into workarounds that no theme can fix.
Content types, fields and relationships
A content type is a kind of page with its own fields: a service has a summary, a price note and related locations, while a team member has a photo, a role and a biography. Relationships link them, so a location page can list its services without anyone retyping them.
Reusable components instead of one big text box
One large editing box invites inconsistent headings, stray fonts and broken layouts. Reusable components give each part of a page a defined shape: a callout, a comparison table, a quote, a call to action. Editors choose a component and fill its fields.
Taxonomies, URLs and what each one creates
Categories, tags and other taxonomies do more than sort content; many platforms create listing pages and addresses for each one. We decide which taxonomies deserve public pages and which stay internal, so the site does not generate thin pages by accident.
The editor experience: publishing without a developer
The test of a CMS build is whether your team can publish a page on a Tuesday afternoon with no one from the agency on the line. We design the editing experience around the tasks your people repeat.
Roles, drafts, approvals and scheduled publishing
Writers draft, an editor approves, a publisher schedules. We map those steps to roles in the platform, so each person sees only the actions that belong to them, and nothing reaches the live site without the right sign-off.
Previews that match the live page
A preview that looks different from the live page erodes trust. In a traditional build the preview is the template itself. In a headless build we wire the preview to the real front end, so editors check the page as visitors will see it.
Translation workflow for multilingual sites
Translated content needs its own states: waiting for translation, in review, approved. We model those states and connect translators to the editing screens. Page design across languages is covered on our multilingual websites page.
Which CMS should you use? A decision rule, not a ranking
No platform wins every case, so we use a decision rule and show our reasoning. The table maps common needs to the platform that tends to fit; our guide to CMS platforms compared goes into the options in more depth.
| Need | Platform that fits | Why |
|---|---|---|
| Marketing site with a small team | WordPress | Familiar editing screens, a large plugin and developer market |
| Complex permissions, multisite or many languages | Drupal | Structured content, fine-grained roles and multilingual tools in core |
| Design-led small site | Webflow | Visual design control with a hosted CMS and fewer moving parts |
| Commerce first | Shopify | Checkout, inventory and payments are the product |
| Content shared with apps or other channels | Headless build | One content source, any front end |
| Rules no platform fits | Custom | Built to the workflow, with an owner for upkeep |
WordPress builds with custom fields
A WordPress build with custom fields turns the familiar editor into a structured one. The Advanced Custom Fields plugin adds extra content fields to edit screens and supports custom blocks, while the block editor lets developers create their own blocks. Details of our work are on WordPress development.
Drupal for complex permissions and multisite
Drupal fits organizations with many departments, strict permissions or several sites on one codebase. Its release schedule lists Drupal 10 reaching its final date on December 9, 2026, so new builds start on Drupal 11.
Webflow, Shopify and site builders
Webflow suits a design-led site that a small team manages, and its developer docs describe a CMS API for creating, updating and publishing collection items. Shopify suits commerce, and its headless docs describe a Storefront API for custom front ends. See Webflow development, Shopify agency, Webflow vs WordPress and WordPress alternatives.
Buyers also compare enterprise suites such as Sitecore, Adobe Experience Manager, Kentico and Umbraco, and headless platforms such as Strapi, Contentful, Sanity and Payload, several of which Astro’s CMS guide lists. They suit particular organizations, and the five questions above apply to them as well. Our builds are on WordPress, Drupal, headless WordPress with Next.js or Astro, Webflow and Shopify.
Custom CMS development services
Custom CMS development services build the editing system itself when no platform fits. Custom CMS development is the most flexible route and the most expensive to keep, so we start by proving that WordPress, Drupal or a headless platform cannot do the job. Buyers who ask for a custom CMS development company usually have unusual approval rules or data.
What is custom CMS development?
Custom CMS development means writing the content store, the admin screens, the permissions and the publishing logic for your workflow, instead of configuring an existing platform. The result matches the process exactly and carries every maintenance duty a platform vendor would otherwise carry.
What owning your own CMS really costs
Security patches become your job. Editors must be trained on a system no one else knows. There is no plugin market to fill gaps, and the knowledge sits with whoever built it, which is a key-person risk. Our guide to custom or off-the-shelf software sets out the broader trade-off.
A middle path: a custom admin on a web framework
When the rules are unusual but the content is simple, a custom admin built on a mainstream web framework can beat both a full custom CMS and a stretched platform. It is closer to application work, covered on our web app development page.
Not sure which CMS your team should be publishing on?Tell us who publishes what, how many languages you run and which systems the site has to talk to. We reply with a free proposal that names the platform, the reasons and a written scope.
Headless CMS development company: when decoupling pays
A headless CMS development company separates the place where content is edited from the place where it is displayed. Headless CMS development services pay off when one content source feeds several front ends or when engineers need full control of the presentation layer.
Headless WordPress with Next.js or Astro
WordPress can act as the editor and content store while another front end draws the pages; its REST API lets outside applications send and receive JSON. Next.js is a React framework for full-stack web applications, and Astro’s guide describes fetching content from a headless CMS and rendering it in Astro. See headless WordPress, Next.js development and Astro vs Next.js.
Previews, caching and rebuilds
Editors need to see a draft before it goes live, while visitors get cached pages. Next.js Draft Mode is built for that: it bypasses cached or pre-rendered content for an editor’s request while other visitors keep the cached version. We plan how content changes trigger rebuilds or cache refreshes, so a published edit appears quickly.
When a traditional CMS beats headless
A headless build adds a second system to deploy, watch and secure. If one site, one team and standard templates cover your needs, a traditional CMS is cheaper and simpler. Compare headless or traditional CMS and headless CMS options before you decide. Google’s guidance on JavaScript search basics notes that server-side or pre-rendering is still a good idea, which headless front ends should plan for.
What is the difference between a CMS and a website builder?
A CMS is software for managing content that you or your developers can extend and host anywhere, while a website builder is a hosted product that bundles design, hosting and editing in one place. Frameworks and web applications sit further toward code.
| Type | Who edits | Who hosts | Limits | Exit cost |
|---|---|---|---|---|
| CMS | Non-developers through admin screens | You or a host you pick | Set by the platform and your developer’s skill | Moderate: content exports, templates rebuilt |
| Website builder | Non-developers in a visual editor | The builder company | Set by the builder’s features | High: content and design often do not transfer |
| Web framework | Developers in code | You or a host you pick | Almost none, but everything is built | Moderate: code is yours, portable |
| Web application | Developers, with admin tools they build | You or a host you pick | Set by what was built | Depends on how the data is stored |
CMS or web application?
Pick a CMS when the main job is publishing pages. Pick a web application when users log in to do things, such as booking, trading or managing accounts. Many products need both, with the CMS running the marketing site and the application behind it.
A CMS without coding: what it can and cannot do
A CMS without coding lets editors change text, images, menus and approved layouts. It cannot create new content types safely, connect systems or fix performance without a developer. The aim of good CMS development is to widen what editors can do alone while keeping risky changes with developers.
CMS integration services
CMS integration services connect the site to the tools your business runs on. We map what moves, in which direction, how often and what happens when a connection fails, before any code is written.
Sending form and content data to the CRM
Form submissions should reach the CRM with source and consent fields intact, and contact records should not create duplicates. Our CRM development work covers the other side of that connection.
Commerce, ERP and product data
Products, prices and stock often live in an ERP or product system, with the CMS holding the surrounding content. We decide which system is the source of truth for each field. See ecommerce development and marketplace development.
Search, digital assets, analytics and APIs
Site search, a digital asset library, tag management and analytics all connect through plugins, modules or APIs. Our API development team builds the interfaces when a ready-made connector does not exist.
CMS migration services: moving platforms without losing traffic
Our CMS migration services move a site from one platform to another while protecting the addresses and content that bring visitors. A CMS migration is mostly planning: what exists, where it goes and how old addresses reach new ones.
Content inventory and field mapping
We list every page, file and field, mark what to keep, merge or retire, and write a mapping sheet from old fields to new ones. Retiring content before the move is cheaper than moving it twice.
Redirect map and parity checks
Google tells site owners to map old URLs to new ones and to use server-side permanent redirects where they can, as its site move guidance and redirect guidance explain. It also suggests keeping redirects for as long as possible, generally at least a year, and warns that rankings may fluctuate while pages are recrawled. A parity crawl then compares old and new pages one by one.
Cut-over and rollback
Cut-over day runs from a checklist, with a tested rollback if a critical check fails. The general process is on website migration. One-off migration support with redirect mapping starts from $3,200 on our one-off SEO projects list. We make no zero-downtime promise.
Enterprise CMS development: many sites, editors and languages
Enterprise CMS development is less about a bigger platform than about more people: many editors, many departments and many markets sharing rules that must hold.
Multisite estates and shared components
Sites that share a design system, components and some content can run on one platform with shared code. The saving is real, and so is the coupling: a change to a shared component reaches every site, so we plan releases with each site’s owner.
Governance for many editors and departments
A written sheet names who owns each section, who may publish, which templates are locked and how a new component gets approved. Without it, an estate drifts into a dozen styles within a year.
Revisions, audit trails and approvals
Larger organizations need to know who changed what and when, and to roll back a bad edit. We turn on revision history, log publishing actions and set approval steps for pages with legal or financial weight.
CMS security and maintenance
A CMS site stays safe through habits: updates applied, access limited, backups tested and plugins chosen carefully.
OWASP Top 10 and plugin supply-chain risk
The OWASP Top 10 for 2025 lists Broken Access Control first, Security Misconfiguration second and Software Supply Chain Failures third. For a CMS, that third item is the plugin or module you add and the libraries it pulls in, so we vet each one for upkeep and avoid unnecessary ones.
Updates, backups with a tested restore and uptime monitoring
Updates run on a staging copy first, backups are restored at least once as a rehearsal, and uptime is monitored. Maintenance is optional, at $50 to $250 a month for a small site; see website maintenance and WordPress maintenance.
How often does a CMS need updating?
Follow each platform’s security releases and apply them promptly, staging first. Minor releases and plugin updates are checked regularly. Because WordPress lists PHP 8.3 or greater among its recommendations, hosting needs reviewing too. Our website security page covers the wider approach.
Accessible templates and accessible authoring
Accessibility has two halves in a CMS: what the templates output, and what the editing tools help authors produce. A theme can be flawless and still publish inaccessible pages if editors are never prompted.
WCAG 2.2 AA in the templates
We build templates to WCAG 2.2 Level AA, including the Level AA criteria Contrast (Minimum), Headings and Labels, Focus Not Obscured (Minimum) and Target Size (Minimum). Non-text Content, which covers text alternatives for images, is a Level A requirement.
Fields that help editors publish accessibly
The W3C’s Authoring Tool Accessibility Guidelines 2.0 include prompting authors for accessibility information, offering accessible template options and helping check and repair problems. In practice that means required alt text fields, heading-level rules in the editor and link-text hints.
Our accessible website design page covers the legal and design side in detail.
Search and AI readiness of what the CMS publishes
The CMS decides what search engines and AI assistants can read: titles, headings, structured data, canonicals and page weight all come from templates and fields.
Structured data generated from fields
Structured data should come from the same fields editors fill in, so it always matches the visible page. Google’s structured data introduction recommends JSON-LD, says the markup must describe content users can see, and notes that it does not guarantee a rich result.
Canonicals, pagination and archive pages
Templates should print a canonical address on every page, handle paginated lists sensibly and avoid creating near-duplicate archive pages for every tag. We set those rules once in the template instead of relying on editors.
Template weight and Core Web Vitals
Heavy templates slow every page. Google’s Core Web Vitals guidance treats a Largest Contentful Paint within 2.5 seconds, an Interaction to Next Paint of 200 milliseconds or less and a Cumulative Layout Shift of 0.1 or less as good, as the Core Web Vitals article explains. See speed optimization and SEO services.

Hire CMS developers: project team or dedicated developer
When you hire CMS developers, the engagement model matters as much as the skills. Teams that need to hire a CMS developer for steady work choose differently from teams with one defined project.
| Model | Best for | What you get | Trade-off |
|---|---|---|---|
| Project team | A defined build or migration | Strategist, designer, developers and QA under a written scope | Changes after sign-off are re-scoped |
| Dedicated developer | A steady stream of changes | One developer on your backlog | Depends on one person |
| Support retainer | A live site needing care | Updates, fixes and small requests each month | Hours must be defined up front |
| White label | Agencies that need a build partner | Work delivered under your brand | Handover rules must be clear |
Details are on dedicated developers and white label web development.
What a CMS web developer should show you
A CMS web developer should be able to show content models, editor screens and migration plans from past work, not only polished homepages. Ask to see how an editor adds a new page type and what happens when a plugin update fails.
UX for editors and visitors
The editing screens deserve the same design care as the public pages, because editors are daily users. Our UI and UX design team designs both sides, and a custom CMS developer should be able to explain choices on each.
What AI assistants say when buyers ask about CMS development
Assistants answer “which CMS” questions from platform documentation and comparison pages. They name a CMS web development company when its page states services, process, prices and limits in plain sentences.
Questions buyers put to assistants
Four questions recur: what CMS development costs, which platform to pick, whether to go headless, and who maintains the site afterward. Each has a direct answer on this page.
Facts we publish so the answer is accurate
Prices, ownership terms and exit terms, stated plainly, with the cases where we advise against a build. For WordPress sites, our AEO for WordPress page explains how to make pages quotable.
How to choose a CMS development company
Compare CMS development companies, including any CMS website development company on your shortlist, on how they answer specific questions. A good CMS web development company shows its working, names who owns what and explains the exit.
Questions to ask a CMS development company before signing
Ask for a sample content model, a staging environment, a plan for training your editors, a statement of who owns the code, and an exit plan. A firm that answers in specifics is easier to trust than one that answers in adjectives.
Red flags: proprietary lock-in and no way out
Walk away from a platform only the vendor can host, a contract that withholds the code, or a build with no content export. Any of them makes leaving expensive.
What you must own
The repository, the hosting account, the CMS admin, any licenses, the domain and a full export of your content. Progression is based in New York City and works remotely with clients in all 50 states and worldwide, and you hold each of those items from day one. If you need a CMS development company in USA coverage, our remote model reaches every state.
How much does CMS development cost?
CMS development cost depends on the platform, the number of content types, the integrations and the migration load. A CMS web development company should quote after a scope, and CMS website development cost for a standard marketing site is the easiest to price.
A website built on a CMS: our fixed-scope rows
These are our published starting prices for sites on a CMS, written as from prices. Full tiers are on fixed-scope website pricing, and broader context is in website development cost.
| Site | From | Notes |
|---|---|---|
| Restyle in place | From $4,800 | New design on the existing structure |
| Brochure site, 5 to 8 pages | From $9,500 | 2 to 3 templates, content plan, redirect map |
| Business site, 10 to 16 pages | From $18,000 | 4 to 6 templates and service pages |
| Bilingual site, 12 to 20 pages | From $26,000 | Two languages written natively |
| Site plus content program | From $36,000 | 30 to 60 pages with internal linking |
| Ecommerce, under 200 SKUs | From $34,000 | Catalog, checkout, product data |
| Ecommerce with ERP, PIM or fulfillment integration | From $78,000 | Integration and data migration |
| Maintenance, optional | $50 to $250 a month | Small site; updates, backups, monitoring |
Custom CMS, headless and integration builds
Custom CMS, headless and integration builds are quoted after a written scope, because the content model, the number of systems and the migration volume change the work more than anything else.
What a CMS costs to run each year
Plan for hosting, any SaaS CMS subscription, domain and licenses, and optional maintenance. A hosted platform often rolls several of those into one bill; a self-hosted one separates them but lets you move.
