Headless Ecommerce Agency London
What is headless commerce?
Headless commerce is the architecture pattern where the storefront (the front end customers see) is separated from the commerce back-office (cart, checkout, inventory, orders) and communicates via API. For a London retailer in 2026 it covers builds on Shopify Hydrogen, Next.js Commerce, Astro and BigCommerce, paired with a headless CMS for content. Faster pages. Cleaner code. More flexible roadmap.
What our headless commerce builds cover
Shopify Hydrogen storefronts
Hydrogen is Shopify's React-based headless framework, deployed on Oxygen or Vercel. We build Hydrogen storefronts with full theme parity to your existing Shopify store, plus the performance gains and design flexibility headless brings. Best fit for Shopify Plus retailers prioritising speed.
- ✓Hydrogen on Oxygen or Vercel deployment
- ✓Server-side rendering for SEO
- ✓Cart and checkout via Shopify Storefront API
- ✓Webhook handling for inventory and orders
Next.js commerce builds
Next.js Commerce is the most flexible headless option. We build Next storefronts against Shopify, BigCommerce, WooCommerce or Saleor back-offices. Edge rendering and ISR keep pages fast. Vercel deployment for global reach.
- ✓Next.js App Router architecture
- ✓Edge rendering and ISR for product pages
- ✓Storefront API integration
- ✓Vercel or self-hosted deployment
Astro and edge-rendered commerce
Astro suits content-heavy commerce where editorial sits alongside products. Edge-rendered, partial hydration, very fast. We use Astro for brands where the storefront is half magazine, half store, and performance has to be exceptional.
- ✓Astro with islands architecture
- ✓Edge rendering on Cloudflare or Vercel
- ✓Headless CMS integration for editorial
- ✓Partial hydration for interactive blocks
BigCommerce headless
BigCommerce is the most headless-friendly traditional commerce platform. We build BigCommerce headless storefronts on Next.js or Astro for B2B and complex catalogue businesses. Strong API. Native multi-currency and B2B features. Plus tier suits brands £5 million+ revenue.
- ✓BigCommerce Stencil to headless migration
- ✓Catalog API integration
- ✓B2B feature configuration
- ✓Multi-currency and tax handling
CMS integration (Sanity, Contentful, Storyblok)
Headless storefronts need a headless CMS for content. We integrate Sanity, Contentful, Storyblok or Hygraph depending on team workflow. Editorial roles, preview environments and content modelling all set up so marketing can publish without engineering.
- ✓Sanity, Contentful, Storyblok or Hygraph integration
- ✓Editorial roles and workflow design
- ✓Preview environments per editor
- ✓Schema validation on content types
Multi-channel commerce
Headless makes multi-channel possible. The same back-office serves the website storefront, a native app, marketplaces and POS without rebuilding the commerce layer. We architect for multi-channel from day one when the roadmap calls for it.
- ✓Single back-office serving multiple storefronts
- ✓App and marketplace integration
- ✓Inventory sync across channels
- ✓Unified analytics and revenue reporting
Our headless commerce process
Architecture decision
We assess whether headless is the right answer. Most retailers under £5 million in revenue do not need it. Once it is the right answer, we pick framework, CMS and deployment together.
Design system and CMS
Component library built in Figma. CMS schemas modelled. Editorial roles defined. Design system feeds the build.
Build and integrate
Storefront built against the chosen API. CMS integrated. Inventory, cart, checkout and order flows tested end to end on staging.
Launch and measure
DNS cutover at low-traffic window. Performance budget verified in production. 30 days of post-launch monitoring included.
"Headless commerce is the right answer when performance is critical, design flexibility matters and multi-channel is on the roadmap. Not before."
