Custom app development

Custom Shopify app development — built around your business

When no app does exactly what you need, we build it: custom apps, theme app extensions, checkout extensions, Shopify Functions and integrations with the systems you already use.

How we build

Apps that last

We build on Shopify’s current platform — Functions, extensions and the GraphQL Admin API — so your app keeps working as Shopify evolves, and we document it so your team knows how it works.

  • Written scope before any code
  • Shopify’s official APIs and extensions
  • Only the permissions the app needs
  • Tested on a development store first
  • Documentation and handover
  • Support after launch

FAQ

Questions, answered

Ask us anything
Will my app be public on the App Store?

Usually not. Most builds are custom apps installed only on your store, which are quicker to build and launch.

Can you extend an app I already use?

Often, yes — through the app’s API or a small custom app that works alongside it.

How much does a custom app cost?

Integrations start from $500. Larger apps are quoted after a free scoping call.
