A modular, API-first headless commerce engine supporting B2B, D2C, multi-vendor marketplaces, subscriptions, and PoS — with zero platform fees and full infrastructure ownership.
CommerceLab is a modular, API-first headless commerce engine designed for the commerce scenarios that Shopify can’t handle: B2B with custom pricing tiers, multi-vendor marketplaces, subscription commerce, and PoS systems that share inventory with online channels. Zero platform fees, full code ownership, and developer-grade control over every commerce workflow.
Shopify and commercetools charge 0.5–2% transaction fees plus $2,000–$40,000/month in platform fees. For high-GMV merchants, that’s millions in annual fees for infrastructure they don’t control and can’t differentiate on. More critically, Shopify’s architecture makes complex commerce scenarios — custom B2B pricing, multi-warehouse fulfillment logic, marketplace splits, subscription renewals — either impossible or dependent on expensive apps that don’t integrate cleanly. Commerce businesses with genuine complexity outgrow consumer-grade platforms faster than they realize.
CommerceLab’s modular architecture means teams use exactly the modules they need — cart, pricing, inventory, fulfillment, customer — and extend or replace individual modules without touching the rest of the platform. The REST and GraphQL APIs serve any frontend: web storefronts, mobile apps, kiosk systems, or voice interfaces. A Next.js storefront starter ships with sensible defaults for teams who want to move fast. The plugin ecosystem covers Stripe, PayPal, Klarna, and 200+ community integrations. For CTOs, the TypeScript/Node.js stack means the same team that builds the frontend builds the commerce backend — no platform expertise silo.
