What is the difference between a private Shopify app and a public app?

A private Shopify app is built exclusively for one store — it accesses the Shopify Admin API without going through the Shopify App Store review process. It's faster to build and ideal for custom integrations with internal tools, ERPs, or India-specific services like Razorpay or Shiprocket. A public app is listed on the Shopify App Store and can be installed by any merchant — it requires Shopify's review and approval process and is suitable for SaaS products targeting multiple merchants.

How long does custom Shopify app development take?

A simple private app or theme extension typically takes 2–4 weeks. A mid-complexity app with Admin UI, webhooks, and third-party API integration takes 4–8 weeks. Full public app development for the Shopify App Store takes 8–16 weeks depending on feature scope. All timelines are confirmed in the project proposal after a discovery call.

Can you integrate our ERP or warehouse system with Shopify?

Yes. We build custom private apps that sync Shopify orders, inventory, and customer data with ERPs like SAP, Tally, Unicommerce, and custom warehouse management systems. The integration uses Shopify's REST and GraphQL Admin APIs combined with your ERP's API or webhook endpoints.

Do you build Shopify theme app extensions?

Yes. Shopify theme app extensions allow apps to inject sections, blocks, and UI elements into a merchant's theme without modifying theme code — which means they survive theme updates. We build extensions for loyalty widgets, custom product options, size guides, review displays, and any feature that needs to appear in the storefront.

What technologies do you use to build Shopify apps?

We build Shopify apps using the official Shopify CLI and Remix framework for embedded app UI, Shopify's REST and GraphQL Admin APIs for data access, Polaris for Admin UI components, and theme app extensions for storefront injection. Backend services are built on Node.js or Python depending on integration requirements.
