Shopify App Development
When off-the-shelf apps don't fully meet your needs, a Shopify app written specifically around your business steps in.
The thousands of apps in the Shopify ecosystem meet plenty of needs; but every brand operates in its own way. When your pricing logic, dealer structure, production process or loyalty scheme doesn't fit the mould of an off-the-shelf app, you end up paying monthly subscriptions and still wrestling with a system that only half works.
Commerslab builds apps tailored to your store on top of Shopify's official APIs and app framework. Whether it's a custom app that runs only on your own store or a public app you want to turn into a revenue model through the Shopify App Store, we run the entire process from development to launch.
Apps tailored to your store
Custom apps run only on your store and are written entirely around your needs. Dealer-based custom price lists, product configurators, pre-order approval flows, stock logic tied to production planning, campaign engines and cart rules for corporate customers are among the solutions we build most often.
Apps are built using the Shopify Admin API, Storefront API and webhooks; they aren't affected by store updates and don't disappear when you change themes.
Public apps for the App Store
If you have a software idea and want to offer it to Shopify merchants as a product, we develop it end to end. A subscription model via the Billing API, multi-tenant architecture, GDPR webhooks, alignment with the Polaris design system and preparation for the Shopify app review process are all part of this scope.
We also provide ongoing support for version management, bug tracking and new-feature development after launch.
Checkout and theme extensions
With Shopify's new-generation extension framework we can add extra fields to the checkout step, shipping rules, gift-wrap options or custom validation flows. Thanks to theme app extensions, the features we build run independently of updates without being embedded in theme code.

Common questions about Shopify app development
Should I build a custom app or a public app?
If the solution only concerns your own operation, a custom app is faster and more economical. If you believe other merchants share the same need and want to turn it into a revenue model, a public app makes sense. We decide together during discovery.
Will the app be affected by Shopify updates?
Because we use official APIs and the extension framework, theme or platform updates won't break the app. We track API version transitions ourselves as part of maintenance.
Can you take over an existing app of mine?
Yes. We review the code of apps built by other teams, take them over, and continue with bug fixing and new-feature development.
