It suits brands that need fast, custom experiences, rich content, or multiple channels, and have the engineering capacity to maintain a decoupled architecture.

It can, through server-side rendering, better Core Web Vitals, and structured data. Results depend on correct implementation and a careful migration plan.

We move in phases, such as catalogue, content, and checkout, behind a routing layer so risk stays contained and each stage is validated.

Headless separates the front end from the commerce back end. Composable commerce goes further by assembling the back end from independent, API-connected components, so each part can be swapped or upgraded on its own.

Timelines vary with catalogue size, content volume, integrations and storefront scope. Moving in phases lets teams release value early and gives a clearer estimate once discovery is complete.
