Compare Audit and Automation Software
18 platforms reviewed on SupplyWolf
Freight Audit and Payment platforms automatically verify carrier invoices against contracted rates, identify billing discrepancies, and process payment — recovering overcharges that would otherwise slip through manual review. Industry studies consistently find 2–7% of freight invoices contain billing errors. For organizations spending tens of millions in annual freight, automated audit platforms pay for themselves multiple times over through error recovery and the staff hours they eliminate from manual invoice matching.

Frequently Asked Questions
Common questions about Audit and Automation software
What is freight audit and payment?
Freight audit and payment (FAP) is the process of verifying that carrier invoices match contracted rates and load data before payment is released. FAP platforms automate this matching, dispute resolution, and payment processing — replacing manual invoice review with systematic, data-driven verification.
How much do companies typically recover through freight audit?
Industry benchmarks suggest freight audit programs recover 1–3% of total freight spend annually through billing error correction. For a company spending $50M in freight, that's $500K–$1.5M in annual savings. The actual recovery depends on contract complexity, carrier mix, and the rigor of rate management.
What are the most common freight billing errors?
Common errors include: accessorial charges (fuel surcharges, detention, residential delivery, liftgate) applied when not applicable; rates that don't match contracted rates or rate tables; duplicate invoices; incorrect weight or classification; and distance errors on mileage-based rates. Accessorial errors are typically the largest category.
Do freight audit platforms work for both TL and LTL freight?
Yes, though LTL is typically more complex due to classification (NMFC), density-based rates, and a wider variety of accessorial charges. Both modes benefit from automated audit. Some platforms specialize in LTL due to its complexity; others handle both equally well.
