The Goods and Service Tax Network (GSTN) had issued the updates on e-invoicing.
E-Invoicing is basically a standard format of the invoice suggested by the GSTN for the GST registered suppliers. E-Invoicing includes that the businesses would generate the invoice at their system and report it to e-invoice portal (also recognized as Invoice Registration Portal or IRP) where a few checks shall be carried out and IRN (invoice Reference Number) would be generated.
