This is a build-to-order Magento 2 / Adobe Commerce extension that puts Indian GST e-invoicing inside your own store — not an instant Adobe Commerce Marketplace download. ECOSIRE designs, develops, installs, and supports the module directly on your Magento install, whether you run Magento Open Source or Adobe Commerce.

The extension ships as a versioned module under app/code/Ecosire/IndiaGstEinvoicing, wired through dependency injection (di.xml) and service contracts so it integrates cleanly with Magento\Sales. When an invoice is created, an observer on sales_order_invoice_save_after (or an admin-triggered action) calls a service that authenticates with your chosen IRP / GSP gateway, submits the invoice payload, and returns the IRN, acknowledgement number, and the IRP-signed QR code — persisted against the order and rendered on the PDF and order view.

E-way bill generation is handled by a second service contract that posts transport, vehicle, and consignment details to the IRP/EWB API and stores the EWB number and validity. HSN/SAC codes map from product attributes through a configurable resolver, and GSTR-ready exports (a CSV/JSON aligned to GSTR-1 fields) are produced by an admin grid + cron job so your finance team can reconcile filings.

Security and operability follow Magento conventions: admin ACL gates configuration and manual re-submission, credentials are stored in encrypted config, failed IRP calls are queued and retried via cron, and every request/response is logged for audit. Optional REST and GraphQL endpoints expose IRN/EWB status to headless frontends or your ERP.

Because it's built to order, scope, gateway choice (your GSP), and field mappings are confirmed with you before development. You get the full source under app/code, an install on your environment, and a defined support window — honest delivery, no marketplace black box.
