Shopify App Development

From $3,0002–6 weeks

The Shopify App Store has thousands of apps — but the more complex your business, the more likely you'll hit a wall. We build private Shopify apps using Node.js and Remix (Shopify's official framework) that extend the platform exactly how you need it. Whether it's a custom discount engine, a supplier feed importer, an automated fulfilment workflow, or a bespoke admin panel — if it can be built on Shopify's API, we'll build it cleanly and maintain it.

Questions about this service

What kinds of apps do you build?

Private apps for a single store — discount logic, custom checkout behaviour via Shopify Functions, supplier feed importers, admin dashboards, fulfilment automation, and API connections to systems that don't have a Shopify integration.

Do you publish apps to the Shopify App Store?

We can build public apps but our focus is private apps custom-built for individual businesses. Public app development involves Shopify's review process and ongoing maintenance that's a separate engagement.

What's the difference between this and App Integrations?

App Integrations is about connecting existing third-party apps (Klaviyo, Recharge, Judge.me) to your store. App Development is building something entirely new that doesn't exist in the App Store.
