e-Invoice Registration on IRP – Who should register, Steps for Registration

Updated on:  

08 min read

Under the new e-invoicing system, a taxpayer will have to generate his invoices on his own accounting/ERP system and then upload the same into the IRP i.e the government’s Invoice Registration Portal. The IRP will then generate a unique Invoice Reference Number, after which, the invoice details are transferred from the IRP to GST portal and e-way bill portal. Therefore, it eliminates the need for manual data entry each time.
