Headless builds separate the storefront from Shopify’s back end, often using Hydrogen or another framework. This gives designers and developers full control over the front end. However, it adds complexity and cost. Therefore, ask an agency to explain clearly why headless fits your goals.
Next, check their engineering depth: performance, caching, hosting and how they keep content editable for marketers. In addition, ask how they handle apps that expect a standard theme, since some won’t work out of the box.
Questions to ask on the first call
First, ask for live headless stores they built and test them on mobile. Next, ask which content management system they recommend. Then ask about ongoing maintenance. Finally, ask for references and the total cost after launch. As a result, you can compare every candidate on equal terms.
Pricing models to compare
Headless projects are larger builds with ongoing development retainers. So compare the full first-year cost, including hosting and support, against a theme-based store. Above all, get every fee in writing.
