Composable commerce
Composable commerce lets retailers assemble their commerce stack from specialized components, such as shop, order management and payment, instead of relying on one all-in-one suite.
Definition
Composable commerce is an approach in which retailers build their commerce stack from specialized, independent components, such as the online shop, order management, payment and search, instead of relying on one all-in-one suite. Each component is chosen for its strengths, often from different vendors, and connected via APIs. The technical foundation is a composable architecture, typically based on the MACH principles: microservices, API-first, cloud-native and headless.
Composable commerce vs. all-in-one suites
An all-in-one suite covers many functions out of the box but ties every part to the same vendor, release cycle and limits. With composable commerce, retailers can replace or upgrade one component, for example search or checkout, without touching the rest of the stack. The trade-off is more integration work and the need for a clear view of which components fit together.
Benefits for retailers
Best-of-breed functionality: each component is chosen because it’s the best fit for that job. Faster change: new channels, markets or features can be added without a full replatforming project. Less vendor lock-in: components can be swapped as requirements or vendors change.
Where an OMS fits in
In a composable stack, the Order Management System (OMS) is the component that connects everything after checkout: it takes orders from every channel, checks inventory across locations and decides where and how each order is fulfilled. Because it sits between the online shop, the ERP and the stores, it needs open APIs and ready-made connectors. fulfillmenttools is built this way and integrates with existing commerce systems through its technology partners.
