Invoiceflow matches each invoice to the PO, receipt and contract pricing, and holds off contract rates. updated: 2026-11-07 --- [Home](https://aavenir.com/) / [Use cases](https://aavenir.com/use-cases/) / Invoice to contract compliance Use case · Invoice to contract compliance # Are we paying what the contract says, or more? Invoiceflow checks every invoice line against the PO, the goods receipt and the signed contract: rates, discounts, tax and payment terms. Lines above the contract rate are held with the clause attached, before anyone pays. Definition ## What is invoice to contract compliance? Invoice to contract compliance means checking each supplier invoice against the signed contract, not only the purchase order: the agreed rates, discounts, price caps, tax and payment terms, before the invoice is approved for payment. A three way match proves the invoice agrees with the PO and the receipt. It cannot tell you that the PO was raised at last year's rate, or that a volume discount should have applied this quarter. [Invoiceflow](https://aavenir.com/solutions/accounts-payable-automation/) reads the contract terms for that supplier and checks them line by line, so AP pays the price procurement negotiated. - Invoices captured from email, the supplier portal and other sources - AI and OCR extraction, with bundled invoices split automatically - Two and three way matching against the PO and goods receipt - Contract pricing, discounts, tax and VAT terms checked against the signed contract - Confidence thresholds route exceptions to the right reviewer Why it leaks ## How invoices get paid above the contract. ### The match ignores the contract PO, receipt and invoice agree with each other, and all three carry the wrong rate. ### Rate cards live in schedules The agreed rates sit in Schedule B of a PDF that AP has never opened. ### Discounts never applied Volume tiers and early payment terms depend on someone remembering them. ### Exceptions cleared to hit a deadline At month end, flagged invoices are approved so the queue empties. How it works ## One staffing invoice, checked before payment. - Email, supplier portal and other sources AI and OCR extract header and line items Bundled invoices are split automatically. - Two way and three way matching PO and non PO invoices, routed by vendor type, spend category or risk Coding and data entry learned from invoice patterns. - Rates, discounts, caps, tax and payment terms from the signed contract Each variance shows the clause it breaks AP and the buyer see the same exception. - Confidence thresholds decide what passes and what goes to a person The reviewer sends back, adjusts or approves with a reason Payment status visible to AP, budget owners and the supplier.

It is the check that each supplier invoice follows the signed contract, not just the purchase order: agreed rates, discounts, price caps, tax and payment terms. Invoiceflow runs that check line by line before approval and holds anything billed above the contract. [See Invoiceflow](https://aavenir.com/solutions/accounts-payable-automation/). ### ### Is three way matching enough to stop overbilling? Not always. A three way match confirms the invoice agrees with the PO and the receipt, but if the PO carries the wrong rate, all three agree and the overcharge is paid. Checking the invoice against the contract pricing closes that gap. [See supplier price increase review](https://aavenir.com/use-cases/supplier-price-increase-review/). ### ### How does Invoiceflow know the contract rate? Invoiceflow works on the same record as Contractflow, so the rates, discounts, tax and payment terms in the signed contract are available when the invoice is checked. Each variance shows the contract and clause it departs from, so the reviewer can act on it. [See Contractflow](https://aavenir.com/solutions/enterprise-contract-management-software/). ### ### Does Invoiceflow require ServiceNow? No. Invoiceflow runs natively on ServiceNow, as it does for the State of Utah and Thrive Networks, and it also deploys standalone for AP teams on other platforms, with the same capture, matching and contract checks.
