Headless Commerce
Headless commerce is an e-commerce architecture that decouples the frontend presentation layer from the backend commerce engine — product catalog, cart, checkout, inventory — connected via APIs rather than a single tightly-coupled platform. This lets a business build custom or multiple frontends (web, mobile app, in-store kiosk) against the same underlying commerce logic, at the cost of more integration work than a traditional platform requires.
What's actually decoupled
In a traditional e-commerce platform, the storefront (what customers see and interact with) and the commerce engine (product data, pricing logic, cart state, checkout, inventory) are tightly bundled — the platform controls both the frontend templates and the backend logic as one system. Headless commerce separates these: the commerce engine exposes its functionality through APIs, and the frontend is built independently, free to use any framework or design approach, consuming those APIs rather than being constrained by the platform's built-in templating.
When it's worth the added complexity
Headless commerce earns its added engineering complexity when a business needs a highly customized frontend experience a traditional platform's templating genuinely can't deliver, needs to serve multiple channels (web, native mobile app, in-store kiosk) from a single consistent backend, or has frontend design ambitions that outpace what a monolithic platform's constraints allow. For a standard storefront without those specific requirements, a traditional platform is usually faster to launch, cheaper to maintain, and involves meaningfully less integration surface area to manage.
Working with Code Ninety
Code Ninety builds both headless and traditional commerce architectures, matching the choice to actual multi-channel and customization requirements rather than defaulting to the more complex option. See the marketplace platform case study for a multi-tenant commerce build.
