Headless E-Commerce

Headless architecture design and implementation — separating the commerce engine (catalogue, cart, checkout, orders) from the frontend presentation layer, connected by API. The frontend can be Next.js, Nuxt, React Native or any framework, while the commerce backend handles the business logic.

• Commerce API design: products, cart, checkout, orders, customers
• Backend commerce engine: custom build or Medusa, Vendure, Commercetools
• Frontend framework: Next.js or Nuxt with API-driven data fetching
• GraphQL or REST API design for efficient data fetching
• Edge caching for product catalogue and category pages
• Webhook events for real-time stock and order updates to frontend
• Multi-frontend strategy: web and mobile app from same API
• Deployment architecture: edge-optimised for performance

Interactive product configurators for businesses selling customisable or configurable products — machinery, furniture, printed products, software licences, bespoke services. The configurator guides the buyer through options, shows a live preview and outputs a correct SKU and price to add to cart.

• Step-by-step option selection with conditional logic
• Live price update as options are selected
• Visual product preview: 2D image swap or 3D model rotation
• Compatibility rules: some options exclude others
• Configuration summary with selected specifications
• Add configured product to cart with option details preserved
• Save configuration for later or share with a colleague
• Configuration-to-quote for sales team follow-up

Bundle and kit product types that let customers build their own bundles from a set of components — selecting items, quantities and variants with a combined price and discount — driving higher average order value and simplifying the purchase of multi-part solutions.

• Fixed bundle: pre-defined combination with bundle pricing
• Configurable bundle: customer selects from defined component set
• Optional add-ons: include or exclude individual components
• Bundle discount: percentage saving vs. buying items individually
• Component stock tracking: bundle blocked if any component out of stock
• Bundle as single line item in cart and on invoice
• Bundle content clearly shown on product and confirmation pages
• Upsell bundle on single product page

Composable commerce approach — selecting best-of-breed services for each capability (PIM, CMS, search, reviews, payments) and connecting them via API to a unified frontend. Each component can be swapped without rebuilding the whole platform.

• PIM integration for product information management
• CMS integration: Contentful, Storyblok or Sanity for content pages
• Search integration: Algolia or Meilisearch for instant search
• Review platform integration: Trustpilot, Yotpo or custom
• Payment provider abstraction: swap providers without checkout rebuild
• Analytics and tracking integration
• API gateway or BFF (Backend for Frontend) layer
• Service versioning and backwards-compatible API evolution

Back-office integration that connects the headless commerce platform to ERP, WMS and logistics systems — synchronising orders, stock levels, customer records and shipment tracking so the commerce platform and back-office always reflect the same data.

• ERP order sync: new orders pushed to SAP, Dynamics or custom ERP
• Stock level sync: ERP or WMS stock pushed to commerce API
• Customer record sync: accounts created in both systems
• Shipment tracking sync: carrier tracking number pulled from WMS
• Return and refund sync between commerce and ERP
• Pricing sync: ERP contract prices reflected in commerce for B2B
• Webhook-based real-time sync for time-sensitive data
• Error handling: failed sync queue and retry with alerting
