Composable Commerce
Building e-commerce systems from interchangeable, best-of-breed components rather than monolithic all-in-one platforms.
Definition
Composable commerce assembles e-commerce infrastructure from modular, specialized services: one vendor for product catalog, another for cart and checkout, another for search, another for personalization. These components connect through APIs and can be swapped independently.
This approach provides flexibility to choose best-in-class solutions for each function and evolve individual components without rebuilding entire systems.
Why It Matters
Monolithic platforms force compromises—you get their checkout even if a competitor's is better. Composable commerce lets organizations optimize each capability independently.
However, composable adds integration complexity and requires technical resources to architect and maintain.
Examples in Practice
An e-commerce company uses Algolia for search, Stripe for payments, Segment for customer data, and a headless CMS for content—composing a custom stack.
A brand outgrows their original checkout solution and swaps in a new provider without touching their catalog or search functionality.
A retailer A/B tests two different personalization engines in parallel, running them against different segments before committing.
