The Indian GST Council approved the implementation of ‘e-Invoicing’ or ‘electronic invoicing’ in a phased manner for reporting of Business to Business (B2B) invoices, starting from 1 January 2020. At this moment that is still on a voluntary basis.
Being the first Invoice Registration Portal (IRP), National Informatics Centre, has made the e-Invoice registration services available through API mode, in addition to other modes. The tax payers and GSPs can integrate their business systems and processes with the e-Invoice system through these APIs for seamless registration of the invoices, generated/prepared on their systems.
