## Product

- [Universal Checkout](https://commercelayer.io/universal-checkout): API-first, stateless

  any payment gateway or tax calculator.

  inventory across multiple stock locations with real-time unified visibility,
  automatic reservation, and intelligent order splitting.

  commerce lets teams assemble best-of-breed tools — CMS, OMS, CRM, PIM, payments — into

  vs. omnichannel selling, and how a unified backend powers consistent experiences across 
  web, mobile, in-store, and AI agents.
