We have found an issue in the agency accounting, in cases an agency "Value date" is set to "First service date" or "Last service date", and the PNR includes a discount, the value date of the invoice would go according to the discount date.
This is now fixed and any new invoices which there was anything on a different date besides flights / charters would be labeled correctly in the invoice value and due date.
As this is only for future invoices, you might need to go an update your agents manually if you encounter such a case in their bookings.
This can be updated using the "UPDATE VD" button in the agency settings.
Should you have any questions about this fix, please contact support.
