Theme developers build or customize the design layer of a Shopify store. The best ones write clean, fast code and build flexible sections, so your team can update pages without help. Therefore, ask to see how they structure sections and blocks.
Next, check performance and accessibility on their past work, especially on mobile. In addition, ask whether they start from a premium theme or build from scratch, since each approach changes cost and maintenance.
Questions to ask on the first call
First, ask how they handle theme updates from the original developer. Next, ask how they test across devices. Then ask what documentation you will receive. Finally, confirm that you will own the finished theme code. As a result, you can compare every candidate on equal terms.
Pricing models to compare
Pricing is usually per project, sometimes with an hourly rate for later changes. So compare what each quote includes, such as the number of templates and revision rounds. Above all, get every fee in writing.
