Invoice Audit Agent: Every Freight Invoice Audited Before a Dollar Gets Paid
Audits every freight invoice against contracted rates, shipment records, and purchase orders. Flags overbillings, accessorial errors, and rate mismatches
Carrier Invoices Contain Errors. Most Never Get Caught
Rate discrepancies, accessorial overcharges, zone errors, duplicate billings. At enterprise freight volumes
Most Invoices Go Unaudited
Legacy audit processes sample 15–30% of invoices at best. The rest pass unchecked. Overcharges in the unaudited portion go unrecovered.
Accessorial Charges Go Unvalidated
Fuel surcharges, detention, and liftgate fees use carrier-specific formulas. Without mode-specific logic, accessorial errors pass every audit.
Rate Cards Drift Out of Sync
Contracted rates change with every sourcing cycle. Rate cards stored in spreadsheets or outdated TMS configs mean audit runs on stale data.
Zone and DIM Weight Errors
Dimensional weight miscalculations and incorrect zone assignments generate recurring overbilling. Without shipment-level validation, errors repeat.
Exceptions Pile Up in Manual Queues
Teams that catch discrepancies face manual queues with no structure, no escalation logic, and no carrier-specific workflows.
No Visibility Into Recurring Billing Patterns
One-off error detection misses the bigger problem: carriers that systematically overbill on specific lanes, modes, or charge types.
Match Every Charge. Flag Every Discrepancy.
Audits every invoice line against contracted rates, shipment data, and PO records. Flags overcharges, auto-approves clean invoices, and routes disputes with evidence.
Intelligent 4-Way Matching
Every invoice validated against contracted rates, confirmed shipment data, purchase orders, and carrier history simultaneously.
Rate Card Synchronization
Contracted rates kept current across every carrier. Audit always runs against today's active terms, not a rate card loaded three sourcing cycles ago.
Mode-Native Accessorial Validation
Fuel surcharge tables, dimensional weight calculations, zone matrices, detention rules, and accessorial schedules applied per carrier, per mode.
Zone and Weight Errors Accumulate
Cross-checks every invoice against PRO numbers, BOL references, and prior payment history. Confirmed duplicates blocked before payment.
Auto-Approval of Compliant Invoices
Invoices passing all audit checks are approved and routed to payment automatically. No human review for clean invoices. First-pass rates above 99%.
Exception Routing with Full Documentation
Every discrepancy categorized by type and severity. Dispute packets generated automatically with original invoice, contracted rate, shipment data, and audit trail.
