What is purchase invoice matching (PO matching)?
Purchase invoice matching, also known as PO matching (Purchase Order matching), is the automated linking of incoming invoices to the corresponding purchase orders and goods receipts. This process ensures that you only pay for what you actually ordered and received, and prevents errors, duplicate payments and fraud. Three-way matching is the gold standard for physical goods.
The challenge in accounts payable
Finance departments spend a significant number of hours each week manually checking purchase invoices. Every invoice must be compared against the original purchase order and the delivery note. For organizations processing hundreds of invoices per day, this is a time-consuming and error-prone task.
The manual process starts at the mailbox or the shared inbox, where invoices arrive in a variety of formats: PDF, scan, e-invoicing or even paper. An employee opens the invoice, looks up the associated order number in the ERP system, compares prices and quantities line by line, and verifies that the delivery actually took place. When discrepancies arise, calls must be made to the supplier or issues escalated internally to the purchasing department. This entire process easily takes twenty minutes per invoice, and for complex orders with multiple lines or partial deliveries, it can take even longer.
Manual matching leads to payment delays, missed early payment discounts, and frustration for both the finance team and suppliers. It also makes the organization vulnerable to errors: an incorrectly typed amount, an overlooked price change or a duplicated invoice are everyday risks. With automated PO matching and smart validation, these problems become a thing of the past.

Manual vs. automated matching
| Feature | Manual | EasyData PO Matching |
|---|---|---|
| Processing time per invoice Time from invoice receipt to approval. Automation reduces this significantly. | 15-30 minutes | ✓ Minutes |
| Error rate Human errors during manual entry and verification. Automated matching reduces typing mistakes. | Variable | ✓ Low |
| Straight-through processing Percentage of invoices processed without human intervention. | 0% | ✓ High |
| Duplicate payment detection Automatic recognition of duplicate invoices prevents costly duplicate payments. | Limited | ✓ Built-in standard |
| Audit trail Full logging of all actions for compliance and audit purposes. | Manual record-keeping | ✓ Automatic |
| Scalability The ability to handle growing volumes without proportional increase in FTE. | Linear with FTE | ✓ Flexibly scalable |
Results vary per organization, invoice volumes and ERP complexity.

How we approach PO matching differently
Smart tolerance settings
Not every discrepancy is a problem. An invoice for €99.50 when the purchase order states €100.00 may not require manual action. Yet many organizations routinely route such an invoice to an employee for manual review, causing unnecessary delays. Our matching engine uses configurable tolerances at multiple levels, so you decide which variances are automatically approved and which require attention:
Amount tolerance: Accept variances up to a fixed amount or percentage. For example, configure invoices with a variance under €10 or 2% to be automatically approved, regardless of supplier.
Quantity tolerance: Flexibility for over- or under-deliveries within agreed margins. With bulk goods, a variance of 3-5% is common, and your system accounts for this automatically.
Supplier-specific: Different tolerances per supplier based on reliability and track record. A supplier with years of flawless deliveries can be granted wider margins than a new partner.
Fuzzy matching for complex situations
In practice, invoices are rarely perfect. Our AI-driven fuzzy matching with machine learning automatically recognizes and corrects deviations:
Order number variations: “PO-2026-001234” is matched with “PO2026001234” or “2026/1234”.
Item descriptions: “Copy paper A4 80gsm” matches with “A4 paper 80gr” from your ERP.
Partial deliveries: Automatic aggregation of partial deliveries for matching against the complete invoice.
