🧾 What is GST E-Invoicing?

E-invoicing is a system under GST where invoices are electronically authenticated through the Invoice Registration Portal (IRP). A unique Invoice Reference Number (IRN) and QR code is generated for each invoice, which must be included on all B2B supplies.

As of now, e-invoicing is mandatory for businesses with turnover above ₹5 crore, and it is gradually being made compulsory for smaller enterprises too.
