E-way bill generation requires consignor and transporter to furnish Parts A and B, with portal-issued reference and recipient acceptance. The E-way bill scheme requires Part A consignment details from the person causing movement and Part B transport details from the transporter or registered person; a registered person may obtain an Invoice Reference Number by uploading an invoice to the portal, which will auto-populate Part A for a limited period. The transporter may generate the e-way bill on the portal using Part A information, the portal issues a unique e-way bill number to supplier, recipient and transporter, and the recipient must accept or reject the consignment within the prescribed timeframe, silence being deemed acceptance.
