Put simply, headless commerce is an ecommerce system that decouples the front-end web system from the ecommerce back-end engine. Most digital stores are built on ecommerce engines that provide both the product offering and processing engine, which is directly integrated with the website, and storefront. A headless ecommerce platform has the front end (or “head”), often a template or theme, separated from the backend mechanics of running an effective ecommerce solution.
