The Statutory e-Invoicing Mandate in India

Under Rule 48(4) of the CGST Rules, the Government of India has phased in mandatory electronic invoicing (e-Invoicing) for B2B supplies, exports, and Credit/Debit notes.

Rather than submitting invoices to tax authorities at the end of the month, eligible taxpayers must report every B2B invoice to an official Invoice Registration Portal (IRP) in real-time. The IRP validates the JSON schema, digitally signs the payload, and returns a unique 64-character Invoice Reference Number (IRN) and a cryptographic signed QR code.

Any B2B invoice issued without an IRN by an eligible business is legally considered null and void, meaning the buyer cannot claim Input Tax Credit and the supplier faces statutory penalties under Section 122.
