What is Composable Commerce?

Home > Glossary > Composable Commerce

Composable commerce is an ecommerce architecture where a company builds its commerce stack from modular, best-of-breed services—such as storefront, search, CMS, PIM, OMS, payments, and personalization—connected through APIs. Instead of relying on a single all-in-one platform, teams can “compose” the capabilities they need and evolve them independently.

Composable commerce is often used by growing and enterprise brands that want more flexibility than a monolithic platform can offer. It supports faster iteration, easier upgrades, and the ability to replace one component (for example, search or CMS) without replatforming the entire ecommerce system.

Key points:

• Modular, best-of-breed services assembled into one stack

• API-first integration between components

• Components can be upgraded or replaced independently

• Commonly paired with headless storefronts and modern cloud infrastructure

• Helps reduce vendor lock-in and “big-bang” migrations

Example: A retailer keeps their commerce engine but replaces the CMS and search with best-in-class tools, integrating everything via APIs.
