Problems We Solve Every Day

If you're experiencing any of these challenges, you're not alone—and we can help.

No existing app meets your needs
Too many apps with overlapping functionality
Need integration with proprietary systems
Manual processes that should be automated
High app subscription costs

The Challenge You Face

The Shopify App Store has thousands of apps, but sometimes none of them do exactly what you need. Or they do too much, are too expensive, or don't integrate with your existing systems.

Custom app development gives you exactly the functionality you need—nothing more, nothing less. Whether it's a private app that automates your unique workflow, an integration with your ERP or PIM system, or a customer-facing feature that doesn't exist anywhere else.

We build custom Shopify apps using modern technologies and Shopify's latest APIs. Our apps are fast, reliable, and built to scale with your business. And because we build them, you own them—no monthly fees to third-party vendors.

From simple automation scripts to complex multi-system integrations, we've built custom solutions for inventory management, order processing, customer experiences, and everything in between.

Frequently Asked Questions

Got questions? We've got answers.

Yes, you own full rights to the code. It's your app—you can modify it, have others maintain it, or do whatever you want with it.

We quote based on complexity and scope. Simple automations might be $10-15K; complex integrations can be $50-100K+. We provide detailed estimates after discovery.

We offer maintenance retainers to handle updates, bug fixes, and enhancements. Shopify occasionally changes APIs, and we'll keep your app working smoothly.

If your system has an API, we can integrate it. We've connected Shopify with ERPs (NetSuite, SAP), PIMs, CRMs (Salesforce, HubSpot), 3PLs, and dozens of custom systems.
