‘E-invoicing’ or ‘electronic invoicing’ is a system in which B2B invoices are authenticated electronically by GSTN for further use on the common GST portal.

Under the proposed electronic invoicing system, an identification number will be issued against every invoice by the Invoice Registration Portal (IRP) to be managed by the GST Network(GSTN).

All invoice information will be transferred from this portal to both the GST portal and e-way bill portal in real-time.

Therefore, it will eliminate the need for manual data entry while filing ANX-1/GST returns as well as generation of part-A of the e-way bills, as the information is passed directly by the IRP to GST portal.
