If you've accidentally issued two tax invoices with the same invoice number, you'll encounter issues uploading them to GSTR-1. To resolve this, you must change one of the invoice numbers, as simply altering the date is insufficient and could lead to problems during GST verification. Adding a suffix like 'A' to one of the invoice numbers is a recommended solution, provided the goods have indeed been transported for both. Always exercise caution when generating invoice numbers to prevent future duplicates.
