Q: Can I change the date of an invoice once it has been saved?
A: Yes. In order to change the date of an AP invoice, open the invoice, hit the "Edit" button on the right side of the screen (second button) and change the invoice date field.
- NOTE* Only AP Invoices which have not been paid can be edited.
