Why Build a Shopify App?

Pricing FAQs

What’s the difference between a public and a custom (private) Shopify app?

A public app is listed on the Shopify App Store and available to all merchants, while a custom (private) app is built specifically for your store’s needs and isn’t visible to others. Custom apps are ideal for internal workflows, API integrations, and store-specific features.

Can you integrate my ERP, CRM, or warehouse system with Shopify?

Absolutely. We specialize in API-based integrations with systems like NetSuite, Zoho, QuickBooks, Microsoft Dynamics, and custom tools. Whether it’s REST or GraphQL, we ensure real-time, secure connectivity.

Do you help with the Shopify App Store approval process?

Yes — we guide you through the entire approval process, from app compliance and performance requirements to testing and listing. Our team has successfully launched multiple public apps.

Will my Shopify app work with future Shopify updates?

Yes. We provide ongoing maintenance and versioning, ensuring your app stays compatible with the latest Shopify API changes, security patches, and platform updates.

How long does it take to build a Shopify app?

It depends on the complexity. Most custom apps take 2–6 weeks, while public apps with additional features and approval steps may take 6–10 weeks. We’ll give you a clear timeline after a quick discovery call.

Do I need to host the app myself?

Yes, Shopify requires that custom and public apps be hosted externally. All you need to do is provide us with an SSH-enabled server — this is a mandatory requirement from Shopify. Once that’s in place, we’ll handle the complete setup, including deployment, database configuration, and ongoing support.
