Catch freight overcharges before payment.
Freight audits can uncover recoverable overcharges equal to 1–5% of transport spend. Duvo checks rates, discounts, fuel and additional fees against the contract and shipment evidence, then submits approved disputes and follows them through to a verified correction or credit. Your team decides which charges to challenge.

Duvo runs the audit work around the systems you already have.
Freight audit breaks down when every carrier, lane, discount, surcharge, and SLA rule needs a manual check before the payment window closes.
- 01Intake
Pick up the invoice.
Duvo reads carrier invoices from email, portal exports, EDI files, AP queues, or TMS records.
- 02Match
Tie it to the shipment.
It matches invoice lines to shipment, lane, carrier, service level, shipment date, and agreed reference data.
- 03Check
Run the contract logic.
Rates, discounts, minimums, fuel surcharge caps, accessorials, detention, and SLA credits are checked line by line.
- 04Approve
Your team decides
Pause where judgement matters.
Overcharges outside policy, ambiguous evidence, and material disputes reach the owner with the case already assembled.
- 05Update
Write it back to SAP.
Approved corrections are applied before the invoice is paid, approved claims go to the carrier and are chased to resolution, and the case status, evidence, and reason codes are written back to SAP.
No freight transformation project required to start.
Systems and control details
Duvo can work through the same systems, files, portals, and inboxes your team already uses, then leave a clear record of the result.

What teams ask about Freight Audit
Which carrier charges does Duvo check against our rate agreements?
Rates, discounts, minimums, fuel surcharge caps, accessorials, detention and SLA credits, line by line. Each invoice line is first matched to its shipment, lane, carrier, service level and shipment date.
Does a disputed freight charge go to the carrier without our sign-off?
No. Overcharges outside policy, ambiguous evidence and material disputes pause for the finance, logistics or transportation owner, with the billed amount, the contract terms and the evidence side by side. Only approved claims are sent to the carrier and chased to resolution.
Where do the carrier invoices need to come from?
Duvo reads them from email, portal exports, EDI files, AP queues or TMS records. Carrier submissions and live system access are scoped separately from the invoice and rate comparison.
Has this pre-payment check been used on real invoices?
The same pre-payment check, run on supplier invoices, protected €2.1M in revenue and €1.4M in margin at Rohlik.
