Most 3PLs obsess over the line-haul rate and ignore the place the margin actually leaks: accessorials. The detention, the lumper fee, the layover, the reweigh. Small charges, buried in the paperwork, spread across hundreds of loads. Individually they look like rounding errors. Added up, they are the difference between a healthy quarter and a flat one.
A driver sat for three hours, the detention was real, but nobody captured it before the invoice went out. That charge is gone.
A carrier bills an accessorial that never happened, or bills it twice, and at volume nobody catches it.
Accessorials are a large share of the money, they arrive on a delay, and the rules are tribal.
The timing makes it worse: accessorials are often invoiced weeks after a shipment closes, landing in a different accounting period than the revenue they belong to, so they never get reconciled.
You stop it by capturing the rules once and checking every load against them automatically.
Which accessorials apply to which customers and lanes, and what each is worth. This is the tribal knowledge that currently lives in one person's memory.
Detention, layover, and reweigh have to be caught at the event, not reconstructed at month-end.
Check what you should have billed the customer, and check what the carrier billed you, against the same ruleset.
Surface the misses with the dollar impact attached, so a human acts on real exceptions instead of hunting for them.
That is precisely what an AI agent is good at: reading the documents, applying the rules, and flagging what is off. It is the same engine behind carrier invoice auditing.
The rules are knowable, the charges are real, and there are simply too many of them for a person to catch by hand. Encode the rules, check every load, and the margin you were leaking comes back.
