What is on a freight quote?
The linehaul for the move, the class and the weight it is rated at, an absolute minimum charge acting as a floor, a fuel surcharge applied as a percentage, and accessorials for whatever the driver and terminal are asked to do at each end.
What is an absolute minimum charge?
It is the least a carrier will charge for a shipment however small it is. Old Dominion publishes it as item 180, with separate intrastate and interstate figures and mileage bands starting at 699 miles or fewer.
Why does the invoice differ from the quote?
Because the quote is built from what you told the carrier. The terminal weighs and measures the load, and anything the driver needed at either end is added afterwards, so a quote is an estimate with a tariff standing behind it.
Which accessorial catches people most often?
The ones that describe an address rather than a service: limited access locations such as residences, schools, construction sites and military facilities, and a lift gate at an end with no dock. Both are known in advance and both are cheaper declared than discovered.
