E-Invoice

‘E-invoicing’ or ‘electronic invoicing’ is a system in which B2B invoices are authenticated electronically by GSTN for further use on the 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. Invoice information will be transferred from this IR Portal to both the GST portal and e-way bill portal in real-time.

 The e-Way bill is an electronically generated document which is required for the movement of goods from one location to another. This document is generated online on the National Informatics Centre (NIC) portal for transportation of goods, both inter and intra state and includes details such as name of consignor, consignee, point of origin of consignment, consignment destination and route. E-way bill is an electronic document generated on the National Informatics Centre (NIC) portal evidencing movement of goods.
