POST-PAYMENT CARRIER BILLING AUDIT
Read-only review.
No workflow changes.
Paid only after recovery.
Your TMS helps process and pay carrier invoices. Gridwork reviews whether the paid charge matched what was agreed.
Detention past agreed free time
Charges that exceed the detention terms on the rate confirmation.
Unauthorized accessorials
Lumper, liftgate, layover, TONU, redelivery, and similar charges not supported by the agreement.
Duplicate invoices
The same load billed more than once, including under different PRO numbers.
Fuel surcharge errors
A surcharge calculated against an outdated schedule or incorrect base.
LTL rating errors
Reclass, reweight, dimensional, and minimum-charge mistakes.
Missed carrier credits
Adjustments or credits that were issued but never reclaimed.
01
Share a sample
Send a 100-load sample. The rate confirmation, carrier invoice, and BOL or POD are usually already attached to each shipment.
02
Audit the documents
We compare each charge to the rate confirmation and supporting load records.
03
Validate and dispute
We separate defensible discrepancies from legitimate charges and handle the carrier recovery process.
04
Recover, then get paid
Recovered funds go to your brokerage first. Gridwork earns a contingency fee only after the money reaches your account.
Industry invoice-audit benchmarks from firms such as Cass Information Systems and AFS Logistics report error and recovery opportunities in the low single-digit range. This is industry context, not a Gridwork result — and the reason historical carrier spend is worth auditing.

The engagement is contingency-based. Terms are agreed before work begins, and Gridwork is paid only after recovered funds reach your account.
Read-only
We work from exports, shared folders, or read-only access; we do not change your TMS or payment workflow.
Limited scope
We review only the records needed for the agreed audit.
Start with what you already have
A CSV export, shared folder, or attachments in the TMS are all workable ways to begin.
What exactly do you review?
We review completed carrier invoices against the rate confirmation and supporting load documents to identify charges that were not owed, including the categories described above.
What documents do you need?
For a 100-load sample, we usually need the rate confirmation, carrier invoice, and BOL or POD. A CSV export, shared folder, or existing TMS attachments can work.
Does this change our AP or TMS workflow?
No. Gridwork works from exports, shared folders, or read-only access. We do not change your TMS or payment workflow.
What if our TMS already matches invoices?
Invoice matching helps process payment. This review asks a separate question: whether the paid charge matched the terms agreed for that completed load.
How are fees calculated?
The engagement is contingency-based. Terms are agreed before work begins, and Gridwork is paid only after recovered funds reach your account.
What happens if a carrier disputes a charge?
We separate defensible discrepancies from legitimate charges. When a discrepancy is defensible, Gridwork handles the carrier recovery process using the supporting shipment records.
How long does a sample audit take?
The sample gives us a practical way to confirm what documents are available and whether the review is a fit. We will agree the scope before any broader audit work begins.
For a 100-load sample, send 100 completed loads with the rate confirmation, carrier invoice, and BOL or POD. A CSV export, shared folder, or read-only TMS access all work.
