By Mehdi HassanHow much does headless Shopify cost?
Headless Shopify costs six figures for most full builds through an agency. Quotes we see for complete headless commerce projects commonly start around €100,000–150,000 and go higher with large catalogs, several storefronts or heavy integrations. Smaller, phased projects can cost less, and prices vary a lot between agencies and scopes.
That figure covers the build. It doesn't cover the cost of running a custom storefront afterwards, which adds up every month and can rival the launch quote over a few years. Before spending either, read our hub on when headless Shopify is worth it, because many stores get most of the benefit from a better theme and a few custom pages.
What do headless Shopify projects cost by scope?
Headless Shopify cost scales with scope: how much of the storefront you rebuild, how many apps and systems you integrate, and how many storefronts you run. The table shows the main scope levels, from the cheapest alternative to a full multi-store build. Where we don't have a reliable market figure, we describe the relative cost instead of guessing.
Scope | What's included | Typical cost we see quoted |
|---|---|---|
Theme plus custom landing pages | Better theme, rewritten key pages, campaign pages on a builder or custom build | Lowest; a fraction of headless |
Partial headless | Content or campaign sections on a custom front end, store on the theme | Mid; depends on content volume |
Full headless, one storefront | Every page rebuilt, apps rewired, CMS, SEO migration | Commonly from €100,000–150,000 |
Full headless, several storefronts | Multiple brands, regions or channels from one codebase | Above the full single-store range |
Ongoing running cost | Upgrades, fixes, new features and pages | Monthly, for the life of the storefront |
- Typical agency quotes we see for a full headless Shopify build
- €100k–150k+
- Designify's monthly retainer for ongoing design and development
- $6,000/mo
- Designify's trial week, to test the fit before committing
- $1,000
If you're comparing headless with themes in more detail, our DTC website cost guide puts a Shopify theme, a custom theme and headless side by side.
What drives the cost of a headless Shopify build?
The biggest cost drivers are app integrations, content modeling and the SEO migration, not the framework. Hydrogen and Next.js cost roughly the same to build with; our comparison of Shopify Hydrogen vs Next.js explains why the choice is about team fit.
- App integrations. Every theme app that touches the storefront, such as reviews, bundles, loyalty and subscriptions, needs an API integration or a custom rebuild.
- Content model and CMS. Designing the CMS so marketers can build pages without developers is real work, and it decides whether the storefront stays useful.
- Design. A custom design system across product, collection, content and account pages. Our design system cost guide covers this part on its own.
- SEO migration. Sitemaps, canonicals, structured data, hreflang, URL mapping and redirects all have to be rebuilt and tested.
- Tracking and analytics. Pixels and events the theme handled are wired up again and checked against checkout.
- Markets and storefronts. Each extra region, language or brand adds templates, content and QA.
- Catalog complexity. Large catalogs, many variants and custom product logic add data work and testing.
What does headless Shopify cost to run each year?
A headless Shopify storefront costs developer time every month to run, plus hosting, CMS and tool fees. Shopify absorbs much of that work for theme stores. In headless, it lands on your team or your agency.
Running cost | Theme store | Headless store |
|---|---|---|
Hosting | Included in Shopify | Oxygen for Hydrogen on most plans, or a separate host for Next.js |
Content management | Theme editor, included | CMS plan or metaobjects, plus setup |
App updates | Mostly handled by app vendors | Integration fixes when APIs change |
Framework upgrades | Theme updates, often simple | Developer work on a regular cycle |
New pages and campaigns | Marketers in the theme editor | CMS sections, or developer time |
Bug fixes and monitoring | Rare front-end issues | Ongoing, especially after releases |
The general principles in our guide to website maintenance cost apply here too, with one difference: a headless storefront is closer to a software product than a website, so maintenance is continuous rather than occasional.
Hypothetical example: comparing three-year totals
For example, suppose a brand is choosing between a custom theme and a full headless build. The theme route costs a design and theme project up front, then a modest amount of developer time a year, because apps and the theme editor cover most changes.
The headless route costs the six-figure build, then continuous developer time for upgrades, integrations and new pages, plus hosting and a CMS plan. Over three years, the gap between them is often wider than the gap between the launch quotes. The right answer depends on whether headless earns that difference through content, integrations or multiple storefronts.
How long does a headless Shopify migration take?
A headless Shopify migration is a multi-month project for most stores, and the timeline depends on the same drivers as the cost: apps, content, markets and catalog size. Treat any very short timeline for a full build with caution, especially if it skips integration and SEO testing.
Phasing helps. Launching content sections or one market first, as our guide to migrating a Shopify theme store to headless describes, spreads the cost and catches problems on lower-stakes traffic. For our own projects, timelines are scoped on the intro call once we've seen the store.
How can you reduce headless Shopify cost?
You reduce cost by building less custom code: fewer custom features, fewer bespoke integrations and a CMS designed so marketers don't need developers for routine work. The cheapest headless storefront is the one that only rebuilds what a theme can't do.
Prove the need first
List the specific limits a theme can't solve. If the list is short, try a better theme and custom landing pages before going headless.
Cut the app list
Remove apps you don't use, and replace the rest with ones that offer headless APIs.
Phase the build
Start with the section or market where headless earns the most, and expand once it's proven.
Design the CMS for marketers
Reusable sections and live preview reduce developer requests for years.
Keep URLs stable
Keeping Shopify's URL patterns shrinks the redirect and SEO work.
Some brands find, after a year or two, that the running cost outweighs the benefit. If that's you, our piece on moving headless Shopify back to a theme covers that route, and our landing page cost guide prices the lighter alternative.
Is a retainer or a fixed project better for headless Shopify?
A retainer is better for headless Shopify when you'll ship storefront changes every month; a fixed project is better for a defined build with a capable in-house team to take over. Headless storefronts rarely stay finished, so most brands need some form of ongoing support.
If you're comparing paths for a different stack, the same logic runs through our guide to Webflow to Next.js migration cost. The retainer isn't for everyone: if your storefront needs only occasional changes, paying monthly for a team is more than you need.
