A custom storefront on top of Shopify (or another commerce backend) with the performance budget headless was supposed to deliver. Product, collection, and cart pages render fast on raw HTML; the checkout flow is polished against your highest-friction edge cases; the schema graph carries Product, Offer, AggregateRating, and BreadcrumbList per page so Google merchant surfaces and AI Overviews both pick the right answer. Pulse audits the launch state and the month-3 follow-up against the same rubric.

Foundations
Every headless commerce engagement inherits the four UX Studio foundations.
Schema graph wired at every URL. Core Web Vitals budget agreed at scope. Crawler-access policy across 18 named AI crawlers. Schema-per-page rather than templated copies. The full foundations grid lives on the UX Studio overview.
Two reasons. Performance ceiling: themes ship with vendor scripts that are hard to budget; headless lets the storefront stay below your INP and LCP targets. Schema control: themes emit generic Product schema; a headless build emits exactly the schema graph you need (Product variants modelled correctly, AggregateRating only when you have real review counts, BreadcrumbList tied to your taxonomy). For smaller stores or simple catalogues, a polished theme is usually still the right call.
Both work. Shopify-hosted checkout is the default. it inherits Shop Pay, fraud rules, tax calculation, and Shopify Plus features without replication. Hydrogen Custom Checkout makes sense when there's a specific buyer journey (subscription configurators, B2B quote-to-order, multi-step gifting) that the hosted checkout can't model. The decision lands at scope, not at week 6.
Standard integrations. Klaviyo for transactional and lifecycle email; Recharge for subscriptions; Yotpo or Okendo for reviews; Shogun and Replo go in the bin (the headless build replaces them). Where an existing store has 10+ ecosystem apps, scope includes an audit of which to keep, which to merge into the storefront code, and which to retire.
Work with valUX
Start where it hurts.
If your organic traffic is sliding, start with a Pulse audit. If you want a programme rather than a one-off, ask about a retainer. Either way, every enquiry is read by a senior architect, and you hear back within one working day.
