In the world of procurement and accounting, accuracy is everything. One powerful method to ensure payments align with what was ordered and delivered is the three-way match. This process compares a purchase order (PO), an invoice, and a receipt to verify consistency before money changes hands. Let’s break it down.
A three-way match is a control process that cross-checks three key documents:
By aligning these, businesses prevent overpayments, fraud, and discrepancies. Here’s how it works and why it matters.
The Purchase Order is the foundation. It’s issued to the vendor and outlines:
This document sets expectations and acts as the first point of reference.
When goods arrive, a receiving report or receipt is generated. It confirms:
This step ensures the vendor met their end of the deal.
The vendor sends an invoice requesting payment. The three-way match verifies:
If all three documents agree, payment is approved. If not, it’s time to investigate.
Prevents Overpayment
Paying for 50 units when only 40 were delivered? A three-way match catches that.
Reduces Fraud
It stops vendors from billing for undelivered goods or inflating prices.
Ensures Accountability
Both buyer and supplier stay honest, with clear documentation to back every transaction.
Simplifies Audits
Regulators or internal reviews love seeing this level of diligence—it’s a compliance win.
Imagine ordering 100 widgets at $10 each (PO total: $1,000). The receipt shows 90 widgets delivered. The vendor invoices for $1,000 (100 widgets). Without a three-way match, you’d overpay $100. With it, you catch the discrepancy, adjust the payment to $900, and resolve the issue with the vendor.
While three-way match ensures payments align with orders and receipts, data analytics takes this control process to the next level. By analyzing trends in mismatches, late deliveries, and invoice variances across suppliers, analytics can highlight recurring issues before they become costly errors. For example, patterns might reveal that certain vendors consistently under-deliver, specific product categories often require adjustments, or particular business units submit POs with frequent discrepancies. This insight allows procurement teams to proactively address root causes, renegotiate terms, or implement targeted training, turning routine compliance checks into strategic operational improvements.
Lasso helps organizations implement these capabilities by building analytics dashboards and models that track three-way match performance in real time. Lasso’s solutions can automatically aggregate PO, invoice, and receipt data, surface patterns of mismatches, and integrate with broader procurement and financial reporting systems. This enables teams to not only enforce accuracy and compliance but also gain actionable insights that reduce operational risk, improve supplier accountability, and optimize cash flow across the organization.
