First up, head over to the purchase tab.
Then find the invoice that you would like to delete and open it up.
Scroll to the bottom of this invoice and click delete.
Please note, you are unable to delete an invoice that is associated with a bank transaction. If you have an associated transaction, remove this first and then delete the invoice. If the associated transaction is locked and you are unable to unlink from the invoice, please liaise with your accountant who will advise how to best proceed.
