Magento 2 India GST Invoicing & E-Invoice (IRN)

Hauptfunktionen

Automatic CGST/SGST vs IGST determination from seller GSTIN state and customer place of supply, computed in a tax total collector plugin and stored per quote_item and order_item

HSN/SAC code mapping via a product attribute, inherited at category level and rendered on every GST invoice line

GSTIN capture at checkout (B2B) with format and check-digit validation, plus optional live verification against the GSTN/GSP API

IRP e-invoice generation: builds the government IRP JSON, submits via your GSP/IRP provider, and stores the returned IRN, signed QR code, and acknowledgement number

GST-compliant invoice PDF with IRN, QR, GSTIN of both parties, place of supply, HSN-wise tax breakup, and reverse-charge flag

Observer-driven workflow on invoice creation so IRN generation never blocks order placement, with a cron-backed retry queue for IRP timeouts

Admin configuration under a dedicated ACL resource: seller GSTINs per source/state, IRP provider credentials, sandbox vs production toggle, and PDF template options

REST and GraphQL endpoints exposing e-invoice status (IRN, QR, ack no., error reason) for headless / PWA storefronts and external accounting sync

Multi-state seller support (multiple GSTINs and source warehouses) with correct place-of-supply logic for stock sold from different states

Credit-note / cancellation handling that generates the IRP cancellation request within the allowed window and updates the customer-facing document

Service contracts (interfaces under Api/) so your accounting/ERP integration consumes a stable API rather than internal models

Configurable rounding and tax display compliant with GST invoice rules, applied consistently across cart, checkout, order, and PDF

Über dieses Produkt

India's GST regime is unforgiving, and Magento's core tax engine was never designed for it. Out of the box, Magento 2 (Open Source) and Adobe Commerce give you flat or rule-based tax rates with no concept of intra-state versus inter-state supply, no CGST/SGST/IGST split, no HSN/SAC mapping, and no path to the government's Invoice Registration Portal (IRP). This extension closes that gap.

ECOSIRE builds this as a custom module under app/code/Ecosire/IndiaGst, wired into Magento via di.xml. We use a custom tax calculation plugin (interceptor) on the tax total collector so CGST/SGST or IGST is selected automatically from the seller GSTIN state and the customer's place of supply, then split and stored on each quote_item and order. HSN/SAC codes attach to products as an attribute and flow through to invoices. GSTIN is captured at checkout and validated for format and check-digit, with optional GSTN API verification.

For e-invoicing, an observer fires on invoice creation, builds the IRP JSON schema, and calls the IRP/GSP API (via your chosen provider — e.g., ClearTax, Masters India, or the NIC sandbox) to obtain the IRN, signed QR, and acknowledgement number. These are persisted and rendered on a GST-compliant invoice PDF. Admin gets ACL-controlled configuration, a cron job for retry/queue handling, and both REST and GraphQL endpoints to read e-invoice status.

This is not an instant Marketplace download. ECOSIRE scopes it to your tax setup, IRP provider, and Magento edition, then builds, installs on your staging, tests against the IRP sandbox, and supports it in production. Honest lead time below.

Post-deployment support window for bug fixes and IRP schema/version updates per the agreed plan

Für wen das ist

Indian D2C / retail merchant on Magento

Sells across multiple states and must issue GST-compliant invoices with the correct CGST/SGST/IGST split and HSN codes, and now crosses the e-invoicing turnover threshold requiring IRN + QR.

B2B wholesaler / manufacturer

Needs GSTIN capture and validation at checkout, place-of-supply tax logic, and IRP e-invoices that their business customers can claim input tax credit against.

Magento agency or in-house developer

Wants a clean, source-available module wired through di.xml, plugins, observers, and service contracts — not an encrypted black box — so they can maintain and extend GST logic alongside their existing customizations.

Häufig gestellte Fragen zu Magento 2 India GST Invoicing & E-Invoice (IRN)

How long does delivery take, since this is build-to-order?

This is custom-built, not an instant download. After a short scoping call we confirm your Magento edition, tax setup, multi-state GSTINs, and IRP/GSP provider. A typical build, staging install, and sandbox testing cycle runs about 2 to 4 weeks depending on complexity (single vs multi-state, headless vs Luma, custom checkout). You get a firm timeline in writing before work starts.

Do I get ongoing support and updates after install?

Yes. Every build includes a post-deployment support window for bug fixes, and we track IRP/GSP schema and version changes (the government updates the IRP JSON schema periodically). Updates within the support window are covered; beyond it, we offer an annual maintenance plan. Because you receive unencrypted source in your own repo, your team can also maintain it independently.

Which IRP / GSP provider do you integrate with?

We integrate with the provider you choose — common options are ClearTax, Masters India, or direct NIC IRP access, and we test against the official NIC sandbox first. If you do not yet have a GSP, we advise on selection. The module is structured so the provider adapter is swappable without rewriting the tax or invoice logic.

Does this work on both Magento Open Source and Adobe Commerce?

Yes. The module is built against Magento 2 service contracts and works on Magento Open Source and Adobe Commerce. On Adobe Commerce we also account for features like B2B company accounts and shared catalogs where relevant to GSTIN and place-of-supply handling. We confirm your exact version during scoping.

Will it handle CGST/SGST vs IGST automatically?

Yes. The tax calculation plugin determines the supply type from your seller GSTIN state versus the customer's place of supply: intra-state supply splits into CGST + SGST, inter-state supply applies IGST. The split is stored per line item and carried consistently through cart, order, invoice, and the GST PDF.

Can my headless / PWA storefront read e-invoice status?

Yes. We expose REST and GraphQL endpoints returning the IRN, signed QR, acknowledgement number, and any IRP error reason, so a PWA Studio, custom React, or external accounting system can read e-invoice status without touching the database directly.
