Frequently Asked Questions
Everything you need to know about the PO Matching Tool.
What is the difference between 2-way and 3-way invoice matching?
A 2-way match verifies that the invoice lines match the Purchase Order (PO) lines. A 3-way match adds a third layer—the Goods Receipt Note (GRN)—to confirm that the quantities invoiced match the actual quantities received, providing the highest level of procurement security.
How do I handle price variances in PO matching?
Price variances occur when the unit price on an invoice differs from the PO. Our tool highlights these discrepancies side-by-side, allowing AP teams to apply variance thresholds and decide whether to approve, dispute, or hold the invoice for exception handling.
Why is automated PO matching better than manual verification?
Manual matching is prone to 'exception fatigue' and human error. Automated matching instantly reconciles line items across large data sets, flagging discrepancies like price variances and duplicate billings with 100% precision, ensuring your ERP remains the single source of truth.
Does this tool support bulk invoice reconciliation?
While this free tool is designed for individual 3-way match verification, the full PerfectParser platform uses AI agents to automate bulk reconciliation across thousands of POs and invoices simultaneously, syncing matched data directly to your ERP or accounting system.
