India GST E-Invoice (IRN) & E-Way Bill Generator

Key Features

IRP e-invoice registration that returns the IRN, acknowledgement number, and government-signed QR code for each qualifying order

One-click e-way bill generation (Part A consignment details plus Part B transporter ID and vehicle number) from the same order screen

Direct GST portal / IRP and NIC e-way-bill integration via your GSP or direct API credentials

Threshold-based auto e-invoicing — only orders above the configured turnover/value rules are sent to the IRP; B2C low-value orders are skipped

Cancellation handling within the statutory 24-hour IRN window and e-way-bill cancellation with reason codes

Amendment workflow that regenerates documents when an order is edited before dispatch

HSN/SAC code mapping per product and tax-rate validation (CGST/SGST/IGST) based on place of supply

Multi-location aware place-of-supply logic so the correct GSTIN and dispatch address are used

Full audit log of every IRP and e-way-bill request/response, with retry and error surfacing in the Admin

About this Product

If your turnover crosses the GST e-invoicing threshold, every B2B invoice must carry a valid IRN (Invoice Reference Number) and a signed QR code from the Invoice Registration Portal (IRP) before goods move — and a separate e-way bill for consignments above the value limit. Shopify has no native concept of an IRN, an e-way bill, or the GST portal, so most Indian merchants paste order data into the NIC portal by hand and reconcile by spreadsheet.

This is a build-to-order Shopify app: ECOSIRE designs, builds, installs, and supports it for your specific store. It is not a one-click App Store download. After purchase we scope your GSTIN setup, place of supply rules, HSN/SAC mapping, and IRP/e-way-bill API access (via your GSP or direct NIC credentials), then deliver a working integration embedded in your Shopify Admin.

What it does once live: when an order is paid (or marked fulfilled), the app reads it through the Admin GraphQL API, builds a schema-compliant e-invoice payload, calls the IRP to register the invoice and return the IRN + signed QR, and writes the IRN, acknowledgement number, and QR back onto the order as metafields so they appear on your invoice template and stay queryable. From the same order you generate an e-way bill in one click — Part A and Part B, transporter ID, and vehicle number — and cancel or amend within the statutory window when an order changes.

Threshold-based automation means low-value B2C orders are skipped and only the invoices that legally require an IRN are processed. The app runs on Shopify OAuth with webhooks for order events, respects your multi-location dispatch points for place-of-supply, and logs every IRP/e-way-bill response for audit. You own the code and the GST portal relationship; we make Shopify talk to it cleanly.

What you get

IRP e-invoice and NIC e-way-bill integration wired to your GSP or direct GST portal credentials

Frequently Asked Questions about India GST E-Invoice (IRN) & E-Way Bill Generator

Is this an instant app I download from the Shopify App Store?

No. This is built to order. ECOSIRE designs, builds, installs, and configures the app for your specific store, GSTIN, and catalog. There is no one-click App Store listing — it is a custom integration delivered to you.

How long does delivery take after I purchase?

Typical delivery is about 2 to 3 weeks from the point we have your GST portal / GSP API credentials and have agreed your HSN/SAC mapping and place-of-supply rules. Complex catalogs or multi-GSTIN setups can take longer; we confirm a firm timeline during scoping.

Do I need a GSP, or can it talk to the GST portal directly?

Both paths are supported. Most merchants connect through a GSP (GST Suvidha Provider) for IRP and e-way-bill access; if you hold direct NIC API credentials, the app can use those instead. We wire it to whichever access you already have or help you arrange it.

What about ongoing support and updates when GST rules change?

ECOSIRE supports and maintains the app after delivery. GST e-invoice schemas and e-way-bill rules change periodically; we offer a support and maintenance arrangement to keep your integration compliant, fix issues, and adapt to API changes. Terms are agreed at handover.

Does it handle cancellations and amendments?

Yes. The app supports IRN cancellation within the statutory 24-hour window, e-way-bill cancellation with reason codes, and an amendment workflow that regenerates documents when an order is edited before dispatch. Every action is written to the audit log.

Will the IRN and signed QR show up on my invoices?

Yes. The IRN, acknowledgement number, and government-signed QR are written back onto the Shopify order as metafields, so they can render on your invoice/PDF template and remain queryable through the Admin API for reconciliation.
