E-Invoice Eligibility Checker

GST e-invoicing requires B2B invoices, debit notes and credit notes to be reported to the Invoice Registration Portal (IRP) to obtain an IRN and QR code before they are issued. It applies once a business crosses the turnover threshold. Enter your aggregate annual turnover to check whether e-invoicing is mandatory for you.

This website provides GST calculators and document generation tools for informational purposes only. Some entities (banks, insurers, passenger transport, cinema tickets, SEZ units, etc.) are exempt from e-invoicing regardless of turnover. Please verify with the official e-invoice portal or a qualified tax professional.

How e-invoicing works

Once mandatory, you prepare the invoice in your billing software, send its JSON to the IRP, and receive a unique Invoice Reference Number (IRN) plus a digitally signed QR code. You must print that QR code on the invoice. Missing this can lead to the document being treated as not a valid invoice, affecting your buyer's input tax credit.
