What is a headless CMS & will your team find it easier to use?
A headless CMS keeps your content apart from your website's design. Your team fills in plain forms, previews the page and publishes, and the layout stays intact. Here's how it works in practice, using Payload, the system we build with, as the example.
A CMS, or content management system, is the screen your team logs into to update the website. In WordPress, the editing screen and the website design are one system. A headless CMS splits them. Your content sits in one place, and the website's code decides how it looks. "Headless" just means the editing system doesn't come with a design of its own.
That sounds like a technical detail. For the people who update your site every week, it changes a lot. The examples below use Payload, the system we build with.
Editing and design live in separate places.
On a typical WordPress site with a page builder, the person adding a project is also doing layout. They drag blocks around, pick sizes and hope the page still looks right on a phone.
In a headless CMS, adding a project means filling in a form. For a construction firm, that might be the project name, client sector, location, contract value, a summary, the photos and the team. The website's code takes those fields and lays them out the same way every time, on every screen size.
Your team can't break the layout.
Because editors fill in fields, a long heading can't push a photo off the page and nobody can pick the wrong shade of blue. The design stays the way it was built. New staff pick it up quickly, because each form only asks for what that kind of content needs.
It also makes your content reusable. A project entered once can appear on its own page, in the project library, on the matching service page and in a list of work for one sector. With a page builder, each of those is usually a separate copy to keep in step.
Adding a project takes a few minutes.
Say you've just finished a hospital extension and want it on the site. Your coordinator opens Projects in the editing screen and starts a new entry. They type the name, pick the sector and the state from lists, add the contract value and a short summary and drop in the photos. The images are resized for phones and desktops automatically. They open the preview, check it on their phone and press publish, or schedule it for the morning the press release goes out.
Nobody touched a layout, and nobody had to wait for a developer.
Payload is the system we use.
Payload is open source under the MIT license, so there's no fee per editor and you aren't tied to one vendor to keep it running. It runs inside the same Next.js code as the website, so there's one application to host and look after. In June 2025 the Payload team joined Figma, and the announcement said Payload stays open source.
You see changes before anyone else does.
- Live preview. Payload can show your real page beside the form, updating as you type.
- Drafts and scheduling. You can save a draft, keep working and publish when it's ready, or set a date and time for it to go live.
- Version history. Earlier versions are kept, so you can go back to the published version if an edit goes wrong.
For bigger changes, like a new page design, each change gets a private preview link you can open on your phone and share with a partner before it goes live.
Each person sees only what they need.
Payload's access control decides who can see and change what. Your HR lead can edit job openings and nothing else. A regional office can update its own projects. If someone isn't allowed to edit a section, it doesn't appear on their screen at all.
One entry can hold several languages.
Payload stores translations field by field, so a project's text in each language sits in the same entry. If a translation is missing, the site can fall back to the main language. We rebuilt iknow.us on this stack. It launched in September 2026 with 108 case studies in four languages, and you can see more of our work in our portfolio.
What changes for your team.
It's worth being straight about the trade.
- There's no plugin store. A new feature or a new kind of page is built by a developer. With us, small changes are often live within a day, after you've checked them on a preview.
- The editing screen looks different from WordPress. We walk your team through it at launch, using your own content.
- Someone has to run the site's code. We host and run every site we build, so that part is on us.
Moving your content across.
Moving to a headless CMS means turning your existing pages into structured entries. For a project library, each old project page is split into its fields: name, sector, location, summary and photos. Much of that can be done by script, with AI tools doing the first pass and a person checking the result. Pages built with a page builder take the most care, because their text is tangled up with layout code. The old addresses are then redirected to the new ones so Google follows, as we explain in moving off WordPress without losing your rankings.
Is a headless CMS right for your firm?
It suits firms with a lot of structured content: projects, case studies, people, locations, services and jobs. It suits firms where several people edit, and firms that want the site to keep looking the way it was designed. For a five-page site that changes twice a year, it's more than you need, and we'll say so.
