INV-01

Definition

INV-01 specifies the e-invoice structure: headers (Version, TranDtls, DocDtls), parties (SellerDtls, BuyerDtls), line items (ItemList) and value details (ValDtls). It draws on the PEPPOL BIS/UBL semantic model adapted to GST. The current version is e-invoice schema 1.1.

Origin

Published by the GSTN/GST Council via the CBIC e-invoicing notifications (starting Notification 68/2019 – Central Tax); format aligned with the PEPPOL standard adopted by India.
