A: It's not difficult to unlock a posted invoice. However, it can cause issues when integrating with your accounting software! Unlocking an invoice will not allow you to repost it. Once it has been posted, you cannot unpost the invoice.
IMPORTANT! Changes made to the invoice will NOT be reflected in any posting or in your accounting software. You can modify the invoice, but you cannot unpost it. Once an invoice has been posted, the posting date CANNOT be changed or removed.
