Headless commerce

Headless commerce separates the customer-facing presentation from underlying commerce logic, connecting them through APIs. A custom storefront can consume pricing, cart and order functions without containing all the business logic itself.[1]

Separation provides design choices but does not eliminate integration work. Define which system owns prices, inventory and order state and how updates reach the storefront. A polished frontend is insufficient when checkout applies a different price from the product page. Headless architecture does not establish consistency automatically.
