The work behind one invoice
An invoice can arrive by email while the purchase order lives in an ERP and the supporting contract sits in a shared folder. The hard part is connecting those pieces and deciding what to do when they disagree.
A useful first step is to map where the documents come from, who is allowed to see them, and which decisions require an approver.
A controlled flow
An illustrative workflow can collect the invoice, retrieve the purchase order and contract, and prepare a match summary with source references. A policy check then routes a clean match or an exception to the appropriate reviewer.
The reviewer should be able to inspect the evidence, change the recommendation, and understand what would be written back to the business system.
What to validate in a pilot
Start with one invoice type and a small set of authoritative sources. Measure missing information, exception frequency, reviewer effort, and the quality of the resulting audit record.
The exact integrations and automation boundary should be agreed before implementation.
