How we build Shopify apps

We follow Shopify's best practices and use the latest tools to deliver apps that are fast, reliable, and easy to use.

Latest Shopify APIs & Polaris UI

Built with Shopify's newest APIs and the Polaris design system for a native look and feel.

Easy Install & Uninstall

Deployed as real Shopify apps. One-click install from your admin, clean uninstall when needed.

Scales With Your Business

Cloud-hosted infrastructure that handles 10 orders or 10,000 orders without breaking a sweat.

No Vendor Lock-in

Your data stays yours. We build on Shopify's standards so you're never locked into our platform.

From idea to a working Shopify app

We take your concept through a proven development pipeline to deliver a polished, production-ready app.

Discovery & Scoping

We learn about your business, map out the requirements, and define exactly what the app needs to do.

Design & Prototyping

We create wireframes and a technical plan. You see what the app will look like before we write a single line of code.

Development & Testing

We build the app using Shopify's latest APIs, test it with your real data, and iterate based on your feedback.

Launch & Support

We deploy the app, help you install it, and provide ongoing monitoring, maintenance, and support.

Apps we've built for merchants like you

Every project starts with a real business problem. Here's how we've solved them.

A 3D printing store needed to auto-create print jobs from Shopify orders
We built SimplyPrintSync — a Shopify app that automatically creates print jobs in SimplyPrint when orders come in. It maps products by EAN, syncs order statuses, and handles yield-per-item configurations. The merchant went from manually entering every order to a fully automated workflow.
A retailer selling on both Shopify and Bol.com needed unified order management
We built BolSync — a complete two-way integration between Bol.com and Shopify. Orders, inventory, shipments, returns, and invoice requests all sync automatically. The merchant manages everything from one Shopify dashboard instead of juggling two platforms.
A growing store needed automatic invoices in Moneybird for every Shopify order
We built MoneybirdSync — an app that creates invoices in Moneybird the moment an order is placed in Shopify. It handles smart contact matching, configurable invoice rules per tag, and even creates credit invoices for returns. The merchant saved hours of bookkeeping every week.
