Composable commerce should solve a requirement that is difficult to meet with the current store. It is not a revenue threshold or a guarantee of better conversion.
Name the requirement before choosing the architecture
Write the customer or operational problem: an unusual product configuration, a connected content experience, or a workflow that crosses systems. Prototype it with the existing Shopify theme approach before assuming a separate frontend is necessary.
Hydrogen is Shopify's framework for building a custom storefront, with Oxygen as a deployment option. It gives a team another implementation approach; it does not remove the work of design, integration, testing and ongoing ownership. Shopify's Hydrogen and Oxygen guidance.
Compare the full responsibility
- Who owns content editing and merchandising?
- Which app features depend on the theme and need a separate implementation?
- Who maintains integrations, analytics, accessibility and performance?
- How will the team preview, approve, release and roll back changes?
Build a like-for-like scope for the theme and custom options. Include the operating team, licences, connector support and training. This guide does not present a claimed dataset of Sonder builds, a universal maintenance premium or a revenue level at which headless pays for itself.
Make the business case explicit
Keep confirmed costs separate from assumed benefits. If the case relies on improved conversion, identify the measurement and a scenario without that uplift. Faster publishing or a necessary capability can be a legitimate reason without a revenue promise.
Prove one journey first
Use representative products, real media and the integrations in scope. Test mobile, keyboard use and the handoff to Shopify's supported checkout. A polished demo does not prove the whole operation is ready.
