What should freight audit software catch?

A manufacturer's accounts payable team receives 300 carrier invoices a month. Most match. Some include a liftgate nobody requested, a reclassification or a second copy of an invoice already paid. Without a check against the booking, they get paid.

Freight audit software should catch 4 problems before payment.

Problem	Example
Rate mismatch	Invoice doesn't match the rate confirmation
Duplicate billing	Same load invoiced twice
Unplanned accessorials	Detention, liftgate, inside delivery not on the booking
Reclassification	LTL class changed after pickup

Extra charges are a real cost: ATRI estimated $3.6 billion in direct costs from truck driver detention in 2023.

What are the main categories of freight audit software?

3 categories of software handle freight audit and reconciliation.

Category	What it does	Where work often stays manual
Audit-and-payment providers	Audit invoices and settle carrier payments, often as a service	Booking data has to be sent to them
Reconciliation tools	Match invoices to rates and flag exceptions	Disputes and follow-up with carriers
AI logistics agents	Book, run, audit, reconcile and pay each shipment	Decisions above the approval limit

The key question is whether the software has the booking. If it didn't book the load, it has to get the agreed rate from somewhere else.

How should teams choose freight audit software?

Ask 4 questions before choosing.

Where does the agreed rate come from? The booking, a contract or a file you send.
Who follows up with carriers on disputed charges?
Do you need audit only, or audit and payment?
Who approves exceptions, and at what limit?

See the invoice doesn't match the quote. Who stops the payment?

How does Wilson, by Cartage, audit and reconcile freight invoices?

Wilson audits each invoice against the shipment it booked, reconciles differences with the carrier and pays after approval. Traditional logistics software gives teams information. Wilson executes the work required to move shipments forward.

Step	Trigger	What Wilson does	When a person steps in
1. Book	Carrier accepts	Records the rate and sends the rate confirmation	Above the approval limit
2. Audit	Invoice arrives	Checks it against the booking	Not required
3. Reconcile	Differences are found	Follows up with the carrier	Not required
4. Hold	A charge wasn't planned	Holds it for approval	Approving or disputing
5. Pay	Invoice is approved	Pays the carrier from the preloaded wallet	Payments above the approval limit

Wilson covers the full lifecycle (create, quote, tender, track, audit and pay) for LTL, FTL, ocean, drayage, parcel and cross-border freight. See how AI automates freight invoice audit, reconciliation and carrier payment.

Why does audit work better when it's part of execution?

Audit works better when the same system books, runs and pays the shipment, because the agreed rate, the documents and the changes are already on one record.

No rate lookups: the rate confirmation is on the shipment.
Fewer disputes: accessorials approved during the load are recorded.
Faster payment: clean invoices are paid without manual matching.

See keep the rate confirmation tied to the invoice.
