Following the GST Council's recommendation, GSTN has begun offering e-invoice registration services through a number of private IRPs as another move towards further digitizing the business process flow. For the purpose of offering these e-invoice registration services to all GST taxpayers in the nation, the GSTN appointed four commercial businesses, namely IRIS Business Ltd – IRIS IRP, Cygnet, ClearTax and E&Y.
Earlier businesses and taxpayers had only one portal of NIC, however, they now have a choice of more than one IRP to register their invoices and generate IRN. This adds significant capacity and redundancy to the single e-invoice registration portal which existed earlier.
