Ask a disputes desk where their threshold is — the invoice amount below which they just pay — and most will say somewhere between USD 200 and 500. Ask why, and the answer is always the same: an hour of a clerk's time costs more than the invoice, and the clerk does not have the hour.
What the hour is spent on
Not on arguing. On finding things. The invoice is in the carrier's portal. The discharge date is in the terminal's system, which may not export history. The empty-return proof is a photo of an EIR on a trucker's phone. The free-time terms are in a contract that procurement negotiated and operations has never seen. The clerk opens five windows, writes the dates on paper, counts on fingers, and decides it is not worth it.
Carriers' billing systems, meanwhile, are not optimised for your contract. They are optimised for the tariff. A container that should have had seven days free under your service contract gets three under the tariff, and nobody on the carrier side will notice unless you do.
The economics flip
If the file builds itself — the invoice is read, the shipment's documents are already in the workspace from when the booking was made, the contract is indexed, the timeline assembles and the clause check says "tariff-rated, 4 days over, USD 440" — then the clerk's hour becomes three minutes, and the threshold drops to zero. A USD 300 invoice that is wrong gets disputed because looking costs nothing.
Across a branch handling 200 import containers a month, with perhaps a third generating some D&D charge and perhaps a third of those over-billed, that is twenty-odd disputes a month that used to be paid. At a few hundred dollars each, it is the margin on a lot of freight.
What it does not change
The decision to send still belongs to a person, and so does the relationship with the carrier's billing team. A desk that sends every weak dispute burns its credibility; the file is explicit about which disputes are strong (contract clause, EDI evidence) and which are goodwill requests (contract silent, screenshot evidence). D&D Pilot is built to lower the cost of looking, not the standard for sending.
