If an invoice is received from a supplier and the “Decline” option is selected, that supplier will need to resend the invoice in order for the “Accept” option to become available once again.

The messaging system can be used in an instance like this to communicate that a mistake has occurred. Please ensure that the "External" tab is used to communicate with the supplier.

The supplier will then have to delete the invoice from their end and then resend the invoice.
