Headless commerce refers to the breaking down of an all-in-one commerce system by decoupling the frontend and backend layers to operate independently. Composable commerce, however, means that every component of the tech stack is independent, and can therefore be “composed” to create the most optimal, customised solution for your business. Like a set of Lego blocks, every element of the tech stack is modular and pluggable, allowing businesses to completely tailor the customer experience.
