composable commerce

[devetn3]

A lot of teams seem to use “headless” and “composable” almost interchangeably, but they solve slightly different problems.

Headless usually starts with separating the frontend from the commerce backend. Composable architecture goes further by allowing teams to choose and replace individual capabilities — search, checkout, CMS, promotions, product data, payments — without rebuilding the entire platform.

This comparison of composable commerce vs headless gives a useful breakdown of where the two approaches overlap and where they differ.

For teams already running a headless setup, I’m curious: what usually becomes the trigger to move toward a more composable architecture — scaling issues, vendor limitations, release speed, or something else?
