Check Every Invoice Against the Contract Before It's Paid.

Rivvun’s agentic AI invoice audit: contract-aware validation of supplier invoices before or during payment approval. Invoice Steward tests each charge against the governing contract, rate card, cap, milestone, credit, fee rule and delivery evidence to decide whether the line is commercially payable.

No. Match compares invoice, PO and receipt, and none of those documents carries the contracted rate, the cap, the credit or the service level. The match can pass while the charge breaches the contract.

AP automation moves the invoice faster; anomaly detection flags statistical outliers. Neither can say whether a charge is contractually payable. Rivvun answers that line by line and states the action: clear, hold or route.

Yes. Invoice Assurance applies audit-grade commercial checks before payment where the evidence exists. Historical paid transactions are handled by Supplier Overpayment Recovery.

Rivvun links the invoice to the SOW, rate card, milestone, timesheet, acceptance record or other evidence. Where evidence is incomplete, the line is routed with the missing evidence named rather than approved or rejected automatically.

Only within policy. Compliant lines clear inside configured thresholds. Every consequential action, such as holding a payment or contacting a supplier, requires human approval, with segregation of duties enforced.

Identified variance, validated variance, prevented value, recovered value and realized hard savings are recorded separately. Prevented value requires evidence the amount was not paid; recovered value requires a received credit, refund or offset.
