E-invoicing under GST

GSTN electronically validates each invoice for further use on a common GST portal. Invoice Registration Portal (IRP) issues a unique IRN number for each invoice and validates the invoice.

E-invoicing is mandatory for all registered persons with an aggregate turnover above 100 Cr in an FY as per the 35th GST Council meeting.

This is a seamless updation of invoice information from IRP to both the GST portal and e-way bill portal consecutively. Thus eliminating the process of manual data entry during GST return filing as well as e-way bill generation.
E-invoicing under GST is mandatory from April 2020.
