Accessorial
Any charge on top of the line-haul rate for extra work, like detention, a lumper fee, tarping, or an extra stop.
An accessorial is any charge beyond the base rate to move the freight. The base pay covers driving the load from A to B. Accessorials cover the extra work around it: detention for waiting, a lumper fee for unloading, tarping a flatbed, an extra pickup or drop, a liftgate, or a layover.
They add up faster than people expect. A load might pay $1,800 on the line-haul, but two hours of detention, a $150 lumper, and an extra stop can be a few hundred dollars more. That money is only yours if you claim it, with the backup to prove it.
The rate confirmation is where the accessorials are set: which ones apply, how much each pays, and what proof the broker needs. Track them on each load so nothing gets forgotten between delivery and invoicing.
