Revised invoices under GST

A revised invoice is issued for supplies made between the date you became liable to register and the date your registration was granted.

Why it exists

During that gap you could not issue GST invoices. Once registered, you issue revised invoices for that period so your customers can claim credit.

Not the same as a credit note

To correct a value or rate on an invoice already issued, you use a credit or debit note, not a revised invoice.
