The problem

Your team is rubber-stamping
invoices they can't fully read.

At 200–300 invoices a month, there's no time to cross-reference every line item. So errors — almost always in the carrier's favor — get paid without question.

⚖️

Reweighs & reclassification

Carriers reweigh at their terminal and bill the heavier number. Often wrong. Almost never disputed because nobody has time.

Phantom accessorials

Liftgate, residential delivery, inside delivery — billed for services that never happened or weren't in your contract.

📋

Wrong rate applied

Carriers bill from their public tariff instead of your contracted rate. The billing department doesn't always know what your sales team negotiated.
