Custom apps solve problems that off-the-shelf apps can’t, such as unique pricing rules, internal tools or integrations with private systems. Therefore, look for developers who know Shopify’s APIs, app extensions and checkout extensibility well.
Next, check engineering basics: secure authentication, rate-limit handling, error logging and tests. In addition, ask whether the app should be private to your store or built for the App Store, because the requirements differ.
Questions to ask on the first call
First, ask whether an existing app already solves your problem. Next, ask how they host the app and monitor it. Then ask who maintains it when Shopify changes its APIs. Finally, confirm you will own the code and the hosting accounts. As a result, you can compare every candidate on equal terms.
Pricing models to compare
Projects are often priced by scope, with a monthly fee for hosting and maintenance. Cheap builds can become expensive when they break. So compare the support terms as closely as the build price. Above all, get every fee in writing.
