What's included
Everything in our Shopify Headless engagement
Every deliverable is scoped upfront. No surprises, no hidden extras.
Sub-Second Load Times
Next.js static generation and edge caching deliver pages in under 200ms — impossible to achieve with a server-rendered Shopify theme.
Full Frontend Flexibility
Complete control over every pixel, animation, and interaction — no Liquid template constraints. Build exactly what your design requires.
Shopify Storefront API
All commerce logic (cart, checkout, customer accounts, product data) served via Shopify's Storefront API so you keep Shopify's reliable backend.
Incremental Static Regeneration
Thousands of product pages statically generated at build time and automatically revalidated when products update — SEO-friendly and fast at any catalogue size.
CMS Integration
Content managed in Contentful, Sanity, or Prismic with Shopify handling commerce data — perfect for content-heavy brands that need editorial control.
Analytics & A/B Testing
Custom analytics pipeline, feature flags, and A/B testing infrastructure independent of Shopify's built-in tools — full data ownership.

FAQ
Your Shopify Headless questions answered
When does headless Shopify make sense?
Headless makes sense when you need performance beyond what Shopify themes can deliver, require full design freedom, need to integrate a separate CMS, or are building a PWA or app-like experience. For most stores, a well-optimised Shopify theme is sufficient and cheaper to build and maintain.
Does headless Shopify still use Shopify's checkout?
Yes — Shopify's checkout cannot be replaced by third parties. The headless frontend handles browsing and cart; at checkout the customer transfers to Shopify's hosted checkout. Shopify Plus unlocks checkout extensibility within this model.
How does SEO work with a headless Shopify store?
Next.js server-side rendering and static generation produce fully crawlable HTML — no JavaScript rendering required by Googlebot. Headless stores typically outperform Liquid stores on Core Web Vitals, which positively impacts rankings.
How much more expensive is headless vs a standard Shopify theme?
Headless builds typically cost 2–4× more than a theme build and require ongoing Node.js hosting (Vercel, Netlify). They also have higher maintenance complexity. We are honest about this trade-off and only recommend headless when the performance or flexibility gain justifies the cost.
How long does a headless Shopify build take?
Most headless Shopify projects take 8–16 weeks depending on catalogue size, custom features, and CMS integration complexity. We provide a fixed timeline at project kickoff.
