Frequently Asked Questions

E-Invoicing can be broadly referred to electronically generated bills exchange digitally with/without compliance component. Generating an invoice through a software such as SAP and Oracle doesn’t amount to e-invoicing. It is important that a certain format is pre-agreed between the parties or government mandates the same and the bill is exchanged electronically between AR and AP departments of the vendor and buyer respectively. In case of ‘with compliance’, e-invoices may need to be reported first to the government system to be validated against e-invoicing guidelines before it is passed on to the buyer either by the vendor or the government itself.

Invoice Registration Portal (IRP) is a registry appointed by Government to generate unique Invoice Reference Numbers (IRN), digitally sign e-invoices and generate QR codes for the e-invoice provided by the Taxpayer. The IRP will also send the signed e-invoices to the recipients on the email provided in the e-invoice. NIC has been appointed as the first and only IRP, but more IRPs will be added in the future.

Invoice Reference Number (IRN) is a hash of supplier GSTIN, supplier’s invoice number and financial year. The hash will be calculated using a hash generation algorithm e.g. SHA256. GSTN is yet to prescribe the final algorithm. IRN shall be unique to each invoice and hence be the unique identity for each invoice for the entire financial year in the entire GST System for a taxpayer. GST Systems will create a central registry where IRN/hash sent by all IRPs will be kept to ensure uniqueness of the same.
