A full custom headless Shopify build typically starts around $20,000 and takes 6–8 weeks. A performance audit and roadmap — the smart first step if you’re unsure — runs about $1,500–$2,500 over roughly two weeks. Pricing is scope-based, not flat-rate, so the real number depends on your design, integrations, and complexity.
What does a headless Shopify build cost?
Here are honest 2026 ranges:
- Performance audit + roadmap: $1,500–$2,500 (~2 weeks).
- Full custom headless build: from $20,000 (6–8 weeks).
- Build + 90-day growth partnership: from $30,000.
These are starting points. The final number scales with how custom your design is, how many integrations you need, and how complex your catalog and flows are.
What goes into the price
A real headless build isn’t a template — it’s custom software. You’re paying for:
- A custom design system built for your brand.
- All core pages: home, collection, product, cart, account, and content.
- Next.js + the Shopify Storefront API, plus a headless CMS for content.
- Validated analytics, deployment, DNS migration, and post-launch support.
- Any third-party integrations — reviews, subscriptions, ERPs, and the like.
Why so much more than a theme?
A theme costs a few hundred dollars because thousands of stores share the same code. A headless build is engineered for your store alone: the performance, the design freedom, and the lack of a template ceiling are exactly what you’re paying for. It’s the difference between renting a template and owning custom software.
How to avoid over- or underpaying
Two failure modes to watch:
- Underpaying: anyone quoting a serious headless rebuild for a few thousand dollars is cutting corners or about to surprise you with change orders.
- Over-committing: if you’re not sure a rebuild is right, don’t spend $20k on a hunch — start with the audit, which credits toward a build if you move forward.
Is the cost worth it?
It’s worth it when a slow or limited store is costing you enough to justify the investment. The clearest proof is conversion: one store we rebuilt went from a 1.29% to a 2.40% conversion rate on the same traffic — a faster, cleaner storefront simply turned more existing visitors into buyers, which is how a build pays for itself.
