The client makes purchase orders from a vendor where shipping costs are already known and to be paid to same vendor. Without adding "shipping cost" in the Purchase Order, the total does not match the actual Purchase Order to be placed with the vendor. How can this "shipping cost" be added in Purchase Order?

One option I am aware is to add "shipping cost" as a non-stock item to the PO. But then, this cost will not get prorated.

Hope there is better way.

Thanks & Regards,
