AnnouncementsBlogE-Invoicing: Benefits & Procedure

April 4, 2019by KNM

E-invoicing or electronic invoicing is a system to generate an electronic document containing transaction information between a buyer and a seller. The Invoice Registration Portal (IRP) gives an identification number to these electronic invoices. The Invoice Reference Number (IRN) generated by IRP will be used to transfer all the invoice information to the GST portal and the e-way bill portal.

The GST e-invoicing system was implemented from October 2020 for those taxpayers whose turnover is Rs 500 crore or more. Earlier, it was planned to implement e-invoicing for businesses with turnover of Rs 100 crore or more in a year
