India and e-Invoice

Updated: Feb 7

A GST (Goods and services tax) invoice is an invoice or document for the products or services that a vendor or service provider offers to a customer. Lists the services and/or products with the total amount to be paid.

From January 2021, taxpayers with a total turnover of more than Rs 100 Cr (approximately US $ 13.7 million) use e-invoices in the last fiscal year and report this to the IRP (Invoice Reference Number ), according to the latest regulation put into effect by the Indian GST Council confirmed that it should. The minimum total turnover amount of 500 Cr was envisaged for the 2019-2020 financial period.

GST e-Invoice System

GST e-Invoice System requires exporters to report e-invoice to the government for verification before delivering it to their customers. To this end, the government has developed many Invoice Registration Portals (IRPs). E-invoice issuers must report their invoices to the IRP. IRP signs the invoice digitally. It then applies a unique QR code along with a unique code called IRN.

Invoice issuers must have a valid GSTIN code. Besides, it must be registered in the GST portal and e-invoicing or e-road invoice portal. At the same time, they need to link their platform to the government platform in the context of all regulations issued by the Indian authorities.

GST invoices must be created in JSON format according to the GST INV-1 scheme. The scheme is based on PEPPOL / Universal Business Language and has been adapted for the Indian market. All invoices must contain the IRN number. The IRN is a numeric, 64-digit code generated by the IRP for each electronic invoice. Only invoices containing IRNs are considered valid.

In addition to PEPPOL / UBL, there are two solution groups developed by SAP.

  • Automated Solution: Direct integration into eInvoicing (IRN) system via GSP. This is a licensed solution developed by SAP that will provide direct integration between SAP ECC or SAP S / 4HANA On-Prem systems or S / 4HANA Cloud and e-Invoicing (IRN) via certified GSPs using the SAP Cloud Integration Platform. This allows taxpayers to upload the payload from the backend SAP system to the eInvoicing (IRN) portal, generate the Invoice Reference Number, and associate the Invoice Reference Number (IRN) with the billing document in the backend system.

  • Manual Solution: The SAP manual process will read the response file and store the IRN, QR code, and digital signature information in the standard table and associate the original invoice with the IRN with the current status in the table. Preparation of a standardized format (JSON request file) needs to be created offline by the customer.
