Freight audit and payment

Freight audit and payment connects invoice accuracy to the moment money leaves AP.

Freight audit and payment, often shortened to FAP, combines transportation-invoice validation with the approval, allocation, remittance, and payment controls that follow. The audit asks whether the carrier bill is supported. The payment process decides what happens to a valid invoice after that review.

01

What is freight audit and payment?

A freight audit checks whether a transportation invoice agrees with the shipment and the commercial terms that should control the charge. Freight payment is the downstream process that approves, allocates, remits, and records payment to the carrier.

When those functions are combined, invoice validation becomes a control in front of payment instead of a separate spreadsheet exercise. The organization can resolve unsupported charges before money leaves, preserve exception evidence, and keep payment status linked to the audited invoice.

Audit and payment are related, but they are not the same service.

A provider can offer audit without processing payments, payment without deep contract-aware audit, or an integrated service that does both. Buyers should ask which functions are actually in scope.

02

How a freight audit and payment workflow works

  1. Invoice intake. Carrier invoices enter through EDI, API, portal export, PDF, spreadsheet, or another agreed source.
  2. Invoice identity. The bill is matched to the correct shipment, load, PRO, tracking number, BOL, business unit, and carrier account.
  3. Commercial authority. The process identifies the contract, tariff, rate confirmation, customer-specific rate schedule, spot quote, fuel rule, or amendment that applied at the relevant date.
  4. Expected-charge calculation. Linehaul, minimums, discounts, fuel, weight, class, service level, and applicable accessorial rules are recalculated.
  5. Exception review. Differences are reviewed rather than automatically promoted into savings. Corrected invoices, credit/rebill chains, missing authority, and ambiguous shipment facts need special handling.
  6. Approval and coding. Valid invoices move through the organization's approval policy, GL/cost-center allocation, and any tolerance or segregation-of-duties controls.
  7. Payment and remittance. Approved amounts are paid and remittance status is preserved.
  8. Reconciliation. Credits, corrections, short-pays, later adjustments, and reversals are matched back to the original economic obligation.
03

What freight-audit controls should test

The exact rules depend on the carrier, mode, contracts, and records available, but common controls include:

  • duplicate invoices and duplicate economic charges;
  • incorrect linehaul, discount, minimum, lane, or spot-rate application;
  • wrong contract or rate version for the shipment date;
  • fuel surcharge discrepancies;
  • unsupported detention, liftgate, residential, limited-access, appointment, redelivery, reweigh, reclassification, and other accessorials;
  • LTL weight, class, FAK, reweigh, reclassification, and minimum-charge issues;
  • parcel service, dimensional-weight, surcharge, correction, and credit issues;
  • currency, tax, business-unit, or allocation inconsistencies when relevant;
  • credits or approved corrections that never post;
  • settlement and reversal mismatches.

The point is not to maximize exception volume. A useful control should distinguish a true supported discrepancy from missing data, tolerance, a valid correction, or an already-known credit.

04

Pre-pay audit and post-payment audit solve different problems

ControlPrimary objective
Pre-pay freight auditFind unsupported charges before AP approves and pays the invoice.
Post-payment freight auditReview historical paid invoices for supportable overpayments, missed credits, or settlement errors.
Second-Look post auditTest whether supportable residual value remains after an existing TMS, provider, or internal audit gets credit for its own findings.

Strong organizations can use all three at different points. Pre-pay controls reduce leakage. Post-payment recovery tests what still escaped. A Second-Look review challenges the residual without pretending the first control environment contributed nothing.

Read the post-payment freight audit guide or see the Second-Look Recovery Audit.

05

What data does freight audit and payment require?

A basic invoice file may be enough to find suspicious patterns, but it is usually not enough to prove every charge. Depending on the environment, a defensible process can require:

  • carrier invoice headers and line items;
  • shipment, BOL, tracking, PRO, load, delivery, weight, and class information;
  • contracts, tariffs, rate sheets, rate confirmations, spot quotes, amendments, and surcharge schedules;
  • carrier account and business-unit mappings;
  • approval, coding, payment, remittance, and credit records;
  • claim correspondence and settlement evidence for post-payment recovery.

Historical authority matters. Applying today's rate to yesterday's shipment can create a neat spreadsheet and a false conclusion.

Common freight audit and payment operating models

Outsourced freight audit and payment

A provider receives invoices, performs the agreed audit, manages exceptions, supports allocation, and administers some or all payment/remittance functions. This can reduce AP workload but creates a larger operational and data relationship.

Software-led audit with internal AP payment

The organization uses audit software or TMS logic to validate invoices while its own ERP/AP process remains the payment authority. This can preserve internal control but requires the team to operate exceptions and integrations.

Internal freight audit

Finance and transportation teams maintain the matching, rating, review, approval, and payment controls themselves. This gives maximum control but requires rate maintenance, exception expertise, and enough staff time to sustain it.

Independent post-payment recovery

A specialist reviews historical paid freight without becoming the payment processor. This is the current RETALLY launch model: bounded audit and, when separately authorized, recovery. RETALLY does not currently present itself as an outsourced freight-payment processor.

07

Payment accuracy and recovery reporting should reconcile

One of the easiest ways to overstate audit value is to collapse every stage into a single savings number. A disciplined process keeps the states separate:

  1. candidate difference;
  2. validated finding;
  3. customer-authorized claim;
  4. submitted/pending/approved/denied claim state;
  5. gross credit, refund, remittance, or other realized benefit;
  6. later reversal or clawback;
  7. net actual recovered funds;
  8. fee-eligible recovery under the signed terms.

The RETALLY Evidence Standard formalizes this boundary. A payment event does not make an unsupported finding valid, and an approved claim does not become recovered money until the applicable realized benefit actually posts.

08

Questions to ask a freight audit and payment provider

  • Which modes, carriers, currencies, and invoice formats are supported?
  • How are effective-dated contracts and rate versions maintained?
  • What happens when rate authority or shipment identity is missing?
  • Which exceptions require a human reviewer?
  • Who approves payment and who can change payment instructions?
  • How are duplicate invoices, corrected invoices, and credit/rebill chains handled?
  • How are GL allocation and business-unit rules controlled?
  • How are credits, short-pays, refunds, remittances, and reversals reconciled?
  • What integrations and data access are required?
  • What is included in pricing: implementation, software, per-invoice fees, payment fees, or contingency recovery?
  • Can the provider prove its headline savings metric from invoice finding through settlement?

Where RETALLY fits

RETALLY is currently positioned for evidence-first historical audit and recovery rather than full outsourced payment processing. The first audit is $0 upfront. If supportable findings exist, the customer decides whether to authorize recovery work under separately confirmed terms.

For companies that already use a freight-payment provider, TMS, or internal audit, the Second-Look model is designed to preserve existing findings and credits before measuring any residual opportunity.

Freight audit and payment FAQ

What does FAP mean in logistics?

FAP commonly means freight audit and payment: validating transportation invoices and then managing the approval, allocation, remittance, and payment workflow for valid charges.

Is freight audit the same as freight payment?

No. Audit tests whether the billed charge is supported. Payment controls the downstream financial settlement. They can be combined operationally but remain distinct control functions.

Can freight audit happen after payment?

Yes. A post-payment freight audit reviews historical paid invoices for supportable discrepancies, missed credits, and settlement issues. Recoverability depends on the evidence, governing terms, deadlines, and engagement scope.

Does RETALLY process carrier payments?

Not as part of the current launch service. RETALLY focuses on bounded historical freight audit and separately authorized recovery. It does not currently present itself as an outsourced freight-payment processor.
