Four high-volume spend categories where AI agents reliably surface recoverable overpayments. Pick one to start — typically your largest or most complex vendor.
Carrier invoicing is dense, accessorial-heavy, and changes weekly. Most leakage hides in fuel, detention, and lane mismatches.
Agency timesheets, bill-rate matrices, and overtime multipliers create dozens of small mistakes that compound across pay periods.
Janitorial, security, landscaping, and maintenance contracts are scope-heavy. Out-of-scope work routinely gets absorbed without change orders.
MRO and indirect materials sit across hundreds of suppliers. Tier pricing, freight terms, and obsolete catalogs are the usual culprits.
One vendor. Two weeks. Evidence-first findings before any fee.
