A user accidentally submitted the same B2B invoice twice in January and sought advice on how to rectify the error. The recommended solution is to issue a credit note against one of the duplicate invoices. While the system typically prevents duplicate submissions, it's advised to check GSTR1 for January carefully, as slight variations in invoice details might have allowed the double entry.

my initial thought too was that normally such thing won't happen. could be on account of any number of reasons include slight difference in mentioning the invoice number. regardless, issue credit note against one and let the other one stay.
