Help/When things go wrong/Void an invoice you haven't sent

Void an invoice you haven't sent

Withdraw a draft invoice that shouldn't have been raised.

What this is for

Voiding says the invoice never happened. It only works before the invoice reaches your accounting software — after that, the invoice exists in your books and a credit note is the right way to undo it.

Tips & gotchas

  • →No Void button means the invoice has already synced. Raise a credit note instead.
  • →Voiding and writing off are different things: a void never happened, a write-off happened and the money never came.
