Headless Shopify: benefits, costs and when to take the plunge

Headless has become one of the most discussed topics in the Shopify ecosystem. Major brands have adopted it, agencies promote it, and many merchants wonder whether they should follow. This article is written for business owners and e-commerce managers: what you gain, what it costs, and how to know whether the time is right. If you are looking for the technical details (Storefront API, cart, orders), read our guide Headless Shopify with Next.js instead.

Headless Shopify in practice

In a traditional Shopify store, the theme displays your products and Shopify handles everything else. In headless mode, Shopify still manages the catalogue, stock, prices, payment, orders and the back office. Only the storefront changes: it becomes a custom website, built with Next.js or with Hydrogen, Shopify’s framework, which queries your store through the Storefront API.

Your teams keep working in the Shopify admin they already know. Your customers, meanwhile, discover a faster, more distinctive store.

What you gain

A much faster store

Over the years, a Shopify theme piles up apps, and each one adds its scripts to every page. A headless store serves pages generated in advance from a global network of servers, with optimised images and very little JavaScript. On mobile, the difference is immediately visible, in Core Web Vitals as well as in the conversion rate.

An experience that reflects your brand

No more limits imposed by the theme and its sections: product configurator, lookbook, guided shopping journey, animations, editorial collection pages. The design is created for your brand, not adapted from a template.

Content and commerce in one place

Combined with a headless CMS, the website freely mixes product pages, guides, blog posts and brand pages. It’s a powerful lever for editorial SEO, as we explain in our article on SEO content strategy.

Several channels, one back office

The same Shopify store can feed your website, a mobile app, an in-store kiosk or a B2B portal for your resellers. Shopify Markets remains available to sell in several countries, with the right currencies and the right languages.

What it requires

• A higher development budget than a theme, since the whole storefront is custom-built.
• Apps to review: those that inject themselves into the theme (customer reviews, upsells, loyalty) don’t work as they are. You need to go through their API or choose compatible alternatives.
• A different editing tool: the Shopify theme editor disappears, and the CMS takes over for editing pages.
• SEO to build: sitemap, tags, product structured data and redirects are no longer provided by the theme. The best practices in our Shopify SEO guide still apply, but it’s up to your agency to implement them.
• Technical maintenance, as with any custom website.

How much does a headless Shopify store cost?

The amounts below are orders of magnitude observed on the market, to help you put a quote in context:

• The Shopify subscription doesn’t change: the Storefront API is available on standard plans. Shopify Plus isn’t required, although it becomes relevant for high volumes or advanced B2B.
• Development: rarely under €15,000 for a polished headless store, and from €25,000 to €60,000 for a complex catalogue, several countries or integrations with an ERP, a PIM or point-of-sale software.
• Hosting: included with Hydrogen (Oxygen hosting), or from zero to a few dozen euros a month on Vercel for a medium-sized Next.js store.
• Maintenance: a monthly package for updates, monitoring and small improvements.

By comparison, a store on a customised theme starts at around €3,000, and a custom theme costs around €10,000 to €15,000. Headless is therefore an investment, which pays off mainly through higher conversion and the freedom it offers. For all price ranges, see our guide to the cost of a website in Marseille.

Signs it’s time to go headless

1. Your store is slow on mobile, despite optimisation, because the theme is overloaded with apps.
2. Every design idea runs into the theme: you keep adding workarounds and custom code.
3. Content matters as much as the catalogue: guides, blog, brand universe, editorial pages.
4. You sell in several countries or across several channels and want a consistent experience.
5. Your store needs to talk to other tools: ERP, PIM, configurator, CRM.
6. Your online revenue is high enough for one extra conversion point to fund the project.

Conversely, a store that is just starting out or a small catalogue doesn’t need headless: a good, well-optimised theme remains more cost-effective. Start with our guide to creating a Shopify store, or with our comparison Shopify or WooCommerce if you are still unsure about the platform.

Hydrogen or Next.js?

Hydrogen, Shopify’s framework, is an excellent choice when the store is the heart of the project: it is designed for commerce and is hosted for free by Shopify. Next.js is better suited when the website mixes a lot of content, other data sources or business features, or when your agency already works with it. In both cases, the store relies on the same Storefront API, and the choice is made case by case.

Going headless without losing your SEO

Moving from a theme to a headless store is a full redesign. Product and collection URLs must be kept or redirected one by one, Product structured data carried over with prices and availability, and the sitemap resubmitted to Google. Our article website redesign without losing your SEO details the method. If you are coming from another platform, also read our guide to migrating to Shopify.
