Accounts payable divisions are heavily prone to administrative error, duplicate supplier billing submissions, and manual reconciliation bottlenecks. Release of vendor payments without verification of goods received leads to direct financial leakage.
What constitutes a Three-Way Match?
Three-way matching is a verification method that checks three critical procurement documents before releasing vendor payment funds:
- The Purchase Order (PO): Reflects the quantities and unit prices originally agreed upon with the supplier.
- The Goods Receipt Note (GRN): Logs the actual quantity of materials checked in by warehouse operators.
- The Supplier Invoice: Represents the payment request compiled by the vendor.
Auditor Validation Guidelines
The table below outlines how Mindron ERP automates match checks across these files, defining strict variance thresholds for each item category:
| Document Type | Primary Key Match | Max Variance Tolerance | Action on Discrepancy |
|---|---|---|---|
| Purchase Order | PO_Number | 0.00% | Auto Hold Voucher |
| Goods Receipt Note | SKU / Qty | 0.50% | Flag for Verification |
| Vendor Invoice | Tax Rate / Price | 1.00% | Reject Invoice Document |
Automated Dispute Resolution
By replacing manual audit checks with a dynamic 3-way validator engine, financial divisions slash duplicate invoicing fraud and administrative verification times by over 80%.
When a vendor invoice arrives, the ERP scans and matches its items against the corresponding PO and GRN logs. If the invoice price or quantity differs from the physical counts registered at warehouse loading docks, the system immediately flags the invoice and locks the payment voucher.
This automated block protects the company from paying for broken parts, overcharged shipping rates, or missing item weights. The system automatically routes the invoice back to the procurement officer to trigger dispute negotiations.
