Headless Commerce

Headless commerce is an architecture where the frontend (what customers see and interact with) is completely separated from the backend commerce engine (inventory, checkout, payments, order management). Instead of the commerce platform rendering your storefront directly, a custom frontend application fetches data via APIs and renders it independently.

In a Shopify Plus context, this means using Shopify as your commerce backend while building a custom React frontend with frameworks like Hydrogen or Next.js. You keep everything Shopify is good at - checkout, payments, inventory - and replace the templating layer with something purpose-built for your brand.

Headless isn't always the right call. It adds cost and complexity. But for brands that need complete design control, sub-second page loads, or content experiences that go beyond product pages, it removes the ceiling that theme-based storefronts hit. Read our guide on when a Shopify Plus store should go headless for a practical framework.

Think: Shopify running the engine, your team designing the car.

Frequently asked questions

What is headless commerce on Shopify?

Headless commerce on Shopify means using Shopify as your commerce backend (checkout, payments, inventory, orders) while building a completely separate custom frontend with frameworks like Hydrogen or Next.js. The frontend fetches data via Shopify's Storefront API instead of using Liquid templates.

When should a Shopify Plus store go headless?

Go headless when you need complete design control beyond what themes allow, sub-second page loads across global markets, or content experiences that go beyond standard product and collection pages. If a well-built OS2.0 theme covers your needs, headless adds unnecessary cost.

How much does a headless Shopify build cost?

A headless Shopify build typically costs $80K-$150K+ and takes 12-20 weeks, depending on storefront complexity and integration requirements. Ongoing maintenance is also higher than theme-based stores because you're managing a custom frontend application.
