Purchase Order Matching Agent
Matches outgoing invoices against customer purchase orders to confirm amounts, line items, and terms align before invoices are sent or payment is expected.
Enterprise and government customers frequently require invoices to reference a valid purchase order, and any mismatch in amount, quantity, or line-item description results in automatic rejection by the customer's accounts payable system, delaying payment for weeks
Sales and delivery teams don't always communicate PO numbers, PO ceilings, or authorized item lists to billing, so invoices go out with missing or incorrect PO references
Tracking PO consumption against a ceiling — so a customer isn't invoiced beyond what their PO authorizes — requires manual spreadsheet tracking that breaks down at volume
Finance ends up firefighting rejected invoices and revising them after the fact, which delays cash collection and strains customer AP relationships
The agent ingests customer purchase orders and their authorized line items, quantities, and value ceilings, then validates every draft invoice against the matching PO before release — checking amounts, item descriptions, and remaining PO balance. Mismatches are held and routed for correction with the specific discrepancy identified, while clean matches are approved for release automatically and PO consumption is tracked in real time.
