Audit freight invoices against what actually happened.

Rates tell you what a shipment should cost. Operational milestones tell you whether the charge should exist at all.

What does freight invoice auditing miss when it only checks contracts and rates?

The shipment itself.

Many freight invoice errors can only be identified by validating charges against the operational events that created them: when the container gated out, when it returned, whether free time had expired, and which accessorial conditions actually occurred.

Gnosis Freight connects invoice charges with live container milestones to perform those checks before payment.

$374,693 recovered from charges that looked small in isolation.

One global automotive importer processed 89,000 charges worth $51 million through Gnosis Freight Invoice Auditing.

Only about 2% were incorrect.

Those errors still represented $374,692.96 in overcharges across 1,289 errors. Up to 85% of the corrections required validating invoice dates and accessorial codes against container milestone data, checks unavailable through contract-rate auditing alone.

Why traditional freight audits leave money behind

A rate can be correct and an invoice can still be wrong.

A detention charge may use the right daily rate but begin on the wrong date. A drayage or accessorial charge may comply with the contract while contradicting what actually happened to the container.

That is why auditing freight spend requires more than matching invoices against a rate card. It requires operational evidence.

How milestone-based invoice auditing works

Connect the invoice to the shipment.

Drayage, detention, per diem, line-haul, and related charges are tied back to the underlying container record.

Validate the event.

Out-gate, empty return, free time, and other milestones determine whether the charge is supported by what happened operationally.

Apply the governing rules.

Automated rules identify charges that should be rejected, disputed, or reviewed.

Make the decision quickly.

Users can approve, dispute, and issue remittance communication in under 60 seconds rather than manually researching each invoice.

Turn a cleaner audit into cleaner freight-spend data.

The result is not merely fewer invoice errors. It is a cleaner freight-spend record.

Validated transportation costs can flow into landed-cost analysis with container-level operational context behind them, while AP spends less time investigating individual charges.

Frequently asked questions about freight invoice auditing

What is freight invoice auditing?

Freight invoice auditing verifies whether transportation charges should be paid. Gnosis Freight goes beyond rate validation by comparing charges with live container milestones, including events such as out-gate and empty return, before funds are released.

Why isn’t checking freight rates enough to audit an invoice?

A charge can use the correct contracted rate and still be incorrect if the underlying operational event does not support it. In this case study, up to 85% of corrections required validating invoice dates and accessorial codes against CLM milestone data, checks that contract-rate audits alone could not perform.

What freight invoice errors can milestone data help identify?

Gnosis Freight matches invoice charges against operational milestones such as out-gate, return, and accessorial events. The case study includes errors across bobtail, CFS, drayage, and detention invoices.

How much money can freight invoice auditing recover?

Results depend on freight volume and error rates. In this case study, a global automotive importer identified 1,289 errors and recovered $374,692.96 from 89,000 charges worth $51 million.

How long does it take to review a freight invoice in Gnosis Freight?

The case study reports that users can approve, dispute, and send remittance communication in under 60 seconds once the invoice has been validated.

Can freight invoice auditing improve landed-cost data?

Yes. Gnosis Freight connects drayage, per diem, line-haul, and other freight costs to the underlying container record, creating more complete unit-level cost data for landed-cost analysis.
