India's e-invoicing mandate requires registered businesses to obtain an Invoice Reference Number (IRN) from the Invoice Registration Portal (IRP) before an invoice is legally valid — and to raise an e-way bill for goods movement above the prescribed threshold. Standard Dynamics 365 Business Central has no native IRP or NIC e-way bill connector, so most Indian teams re-key invoices into a portal or an external GSP tool. That breaks the audit trail and invites mismatches.

This is a build-to-order extension, not an instant AppSource download. ECOSIRE builds it in AL as a per-tenant extension installed directly on your Business Central environment (cloud SaaS or on-prem), wires it to your chosen GSP/IRP (such as a NIC-authorised GST Suvidha Provider), and supports it after go-live.

The extension adds a GST e-invoicing action to Posted Sales Invoices and credit memos. On submit it assembles the government JSON schema from your posted document, GST registration, HSN/SAC codes and place-of-supply, calls the IRP through your GSP API, and stores the returned IRN, acknowledgement number, signed QR code and status back on the document via table and page extensions. E-way bills are generated and updated (transporter, vehicle, Part-B) from the same record. Cancellation within the statutory window and credit-note-based amendments are handled with reason codes.

Submission runs single-click per document or in bulk through a Business Central job queue. Every IRP/NIC call, response and error is logged for reconciliation. Permission sets, field-level setup and GSP credentials are scoped per your tenant. You own the source. Pricing is a one-time build fee; the IRP mandate, GST schema, HSN catalogue and your GSP subscription remain your responsibility, and ECOSIRE adapts the extension as the schema evolves.
