India GST E-Invoicing (IRP) Connector for Magento 2

Key Features

IRN generation by submitting the e-invoice JSON to the GSTN Invoice Registration Portal (IRP) and persisting the returned IRN + acknowledgement number against the Magento invoice

Signed GST QR code rendered on the invoice PDF and order/invoice view, decoded straight from the IRP-signed response

HSN/SAC code mapping per product or product attribute, with category-level defaults and validation before submission

E-way bill generation support — Part-A/Part-B payload assembly and transporter/vehicle fields driven from shipment data

GSTR-1 export and reconciliation helpers (B2B, CDNR sections) to cross-check registered IRNs against your filing

Built as a clean module under app/code/Ecosire/GstEInvoicing with service contracts, repositories and an IRP gateway client wired via di.xml

Observer on sales_order_invoice_save_after for automatic IRN generation, plus a manual admin action and cron retry for failed/queued submissions

IRN cancellation within the statutory 24-hour window from a custom admin grid, with reason codes logged to an audit table

Admin ACL resources so only authorized roles can generate, retry, or cancel IRNs (Adobe Commerce role scoping respected)

REST and GraphQL endpoints exposing IRN, QR and e-way bill status for headless/PWA storefronts and ERP/middleware integrations

Sandbox-first configuration: toggle between GSTN sandbox and production IRP endpoints with environment-specific GSP/ASP credentials stored encrypted in core_config_data

Multi-GSTIN / multi-source support for merchants billing from more than one registered place of business

Structured logging, retry with backoff, and graceful handling of IRP duplicate-IRN and timeout responses so a portal outage never blocks order processing

About this Product

India's GST e-invoicing mandate requires every covered B2B invoice to carry a government-registered Invoice Reference Number (IRN) and a signed QR code issued by the Invoice Registration Portal (IRP) before it is legally valid. Out of the box, neither Magento Open Source nor Adobe Commerce speaks to the GSTN IRP — so Indian merchants either re-key invoices into a portal/ASP by hand or stitch together brittle scripts. This extension closes that gap natively inside Magento.

ECOSIRE builds this as a proper Magento 2 module under app/code/Ecosire/GstEInvoicing — service contracts for IRP request/response, an IRP gateway client wired through di.xml, and an observer on sales_order_invoice_save_after (or an admin/cron trigger you choose) that assembles the e-invoice JSON, calls the IRP via your registered GSP/ASP or direct API credentials, and persists the returned IRN, acknowledgement number, and signed QR against the invoice. The signed QR is rendered on the PDF and the customer-facing invoice; a custom admin grid with ACL-scoped permissions lets your team view, retry, and cancel IRNs within the statutory window.

Because this is build-to-order, it is not an instant Adobe Commerce Marketplace download. We scope it against your store — your Magento version (Open Source or Adobe Commerce), tax classes, HSN/SAC structure, multi-GSTIN setup and theme — then build, install on your environment, and support it. The connector ships with HSN/SAC code mapping, e-way bill generation support, GSTR-1 export/reconciliation helpers, and both REST and GraphQL endpoints so headless/PWA storefronts and ERP middleware can read IRN status. We handle GSTN schema changes as the IRP spec evolves, under a support agreement. Honest, sandbox-tested, and yours.

What you get

Custom Magento 2 module (Ecosire_GstEInvoicing) installed under app/code on your environment, version-pinned to your Magento/Adobe Commerce release

IRP gateway integration configured against your GSP/ASP or direct API credentials, tested first in the GSTN sandbox

Admin configuration section, custom IRN management grid, and ACL resources, plus invoice PDF templates updated with the signed QR

REST and GraphQL endpoint documentation for IRN, QR and e-way bill status

HSN/SAC mapping configured for your catalog and a GSTR-1 export aligned to your filing workflow

Deployment notes, a short admin runbook, and a sandbox-to-production go-live checklist; source code is yours

Who this is for

Indian B2B Magento merchant under the e-invoicing mandate

Sells on Magento Open Source or Adobe Commerce above the GST e-invoicing turnover threshold and must attach a valid IRN and signed QR to every covered B2B invoice without manual portal re-keying.

Finance / GST compliance lead

Owns GSTR-1 filing and audit readiness. Needs IRNs generated reliably, cancellations tracked within the 24-hour window, and a reconciliation export that ties registered invoices back to the return.

Magento technical lead or integration partner

Maintains the store and any ERP/middleware. Wants a clean app/code module using service contracts, di.xml and REST/GraphQL — not theme hacks or core edits — so it survives upgrades and plugs into existing systems.

Frequently Asked Questions about India GST E-Invoicing (IRP) Connector for Magento 2

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

Typical delivery is about 2 to 4 weeks from when we receive your Magento details and GSP/ASP (or direct IRP) sandbox credentials. We scope your version, tax and HSN/SAC setup first, build and test against the GSTN sandbox, then install and validate on your environment before flipping to the production IRP. Complex multi-GSTIN or headless/PWA setups can extend the timeline — we confirm a firm date during scoping. This is not an instant Adobe Commerce Marketplace download.

Do you provide ongoing support and updates after go-live?

Yes. The GSTN IRP schema and e-invoicing/e-way bill rules change over time, so we offer a support agreement covering schema/spec updates, bug fixes, and compatibility with Magento and Adobe Commerce upgrades. The one-time build price covers the initial delivery; ongoing support is arranged separately so your IRN generation keeps working as the mandate evolves.

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

Yes. It is a standard module under app/code using service contracts, di.xml, observers and admin ACL, so it runs on both. On Adobe Commerce we respect the finer-grained admin roles and can align with Commerce-specific features in your store; we confirm your exact edition and version during scoping and pin the build to it.

How does the IRP connection actually work — do I need a GSP or ASP?

E-invoices are registered with the GSTN Invoice Registration Portal, which is reached either directly with API access or through a GST Suvidha Provider (GSP) / ASP. We integrate with whatever access you hold: the module assembles the e-invoice JSON, authenticates, submits it, and stores the returned IRN, acknowledgement number and signed QR. We always test against the GSTN sandbox before any production submission. We do not resell IRP/GSP access — you provide the credentials, we wire them in securely.

What happens if the IRP is down or rejects an invoice?

The connector logs every request and response, retries with backoff on timeouts, and handles IRP error cases like duplicate-IRN gracefully. A failed submission is queued and surfaced in the admin grid for manual or cron-driven retry, so an IRP outage never blocks your order or invoice workflow. Cancellations are supported within the statutory 24-hour window with reason codes recorded to an audit table.
