Duplicate Invoice Number

[Sudhir Chugh]

Due to some software glitch same invoice number issued to two parties. One invoice already uploaded on GST portal .For other the other invoice goods were supplied under Ewaybill and same invoice number mentioned. How should i rectify this error.

Sir, 

"e-Way Bill " can only be amended within 24 hours of its generation. When the time is passed, the only solution is to cancel the same. When the invoice itself is wrong or has a repeated invoice number, the same has to be cancelled duly recording in the books of accounts and a fresh invoice and e-Way Bill have to be issued.

Edit the invoice number for the invoice for which EWB and e invoice not issued by adding any suitable alphabet.

If this cannot be done issue a credit note and then another invoice.

AI Summary

Duplicate invoice numbers: amend identifiers or cancel and reissue invoices and e Way Bills to maintain GST compliance.
Duplicate invoice numbers from a software glitch must be corrected: an e Way Bill may be amended only within 24 hours, after which cancellation and reissuance is required; invoices not issued as e invoice/e Way Bill can have their identifier edited (for example by appending a letter), or if editing is not possible, a credit note should be issued, the incorrect invoice cancelled in the books, and a fresh invoice and e Way Bill issued.
