Carrier Upcharge %
The carrier upcharge is applied to the incoming freight value from UPS/FedEx before it is applied to the shipment. It should be entered as a percent value. This field is enabled only if the Bill Transportation To field is Shipper.
This is a flat percentage upcharge with no financial tracking. For example, if the incoming freight value is $100 and you have a carrier upcharge of 10%, the total freight billed is $110; the 10% is not tracked financially.
