- Accidental duplicates: You might have accidentally generated the same invoice twice.

If the issue is minor, like a simple typo, the easiest solution is to void the incorrect invoice and create a new one with the correct number. Think of it like this: imagine writing a check with a wrong number – you’d simply void it and write a new one.
