India GST E-Invoicing & E-Way Bill for Shopify is a build-to-order Shopify app that closes the compliance gap Shopify leaves open for GST-registered Indian merchants: Shopify can take the order, but it cannot generate an IRP-cleared IRN, a GST-compliant signed QR invoice, or an e-way bill. We build that engine for your store and install it for you.

This is not an instant App Store download. After purchase, ECOSIRE builds the app against your store, your GSTIN, and your chosen IRP/GSP (e.g., NIC IRP or a registered GSP), then installs it as a custom Shopify app using OAuth and the Admin GraphQL API.

How it works. An orders/create (or orders/paid) webhook fires when a customer checks out. The app reads the order, your multi-location dispatch origin, and line-item HSN/SAC codes mapped from product metafields, builds the IRN payload, submits it to the IRP, and writes the returned IRN, acknowledgement number, and signed QR back onto the order as metafields. Where the consignment crosses the value/movement threshold, it generates the e-way bill (EBN) with transporter and vehicle details.

What you get: correct B2B vs B2C handling, CGST/SGST/IGST logic by place-of-supply, GSTIN validation, cancellation within the IRP window, and GSTR-1-ready exports your accountant can reconcile.

You own the result — a private app on your own Shopify store, scoped to your data, with no per-invoice SaaS lock-in. ECOSIRE delivers it configured, tested against the IRP sandbox, and documented, then supports it. Compliance rules and IRP schemas change; we keep your build current.
