How Does Epicor AP Invoice Matching Work?
The matching process begins when an invoice is entered or imported into the ERP system. Invoice data is then compared with relevant purchasing and receiving records. The objective is to establish that the amount being claimed by the supplier aligns with what the company ordered and received.
- Invoice identification: Verify the supplier account, invoice number, invoice date, currency, and total amount.
- Purchase order comparison: Compare invoice line descriptions, quantities, unit prices, and agreed charges with the purchase order.
- Receipt verification: Check received quantities against invoiced quantities using the available goods receipt records.
- Variance evaluation: Identify differences in quantities, prices, taxes, freight, or other charges and compare them with configured tolerances.
- Workflow progression: Route invoices that satisfy the applicable checks toward approval and posting, while directing exceptions for clarification or authorized resolution.
This structured approach makes invoice processing more consistent by connecting supplier claims to documented purchasing activity and financial records.
Two-Way and Three-Way Invoice Matching
The matching method depends on the information required to verify a transaction. Two-way matching compares the supplier invoice with the purchase order. It is commonly used when the order and agreed pricing provide the necessary evidence for invoice verification.
Three-way matching adds the goods receipt or service receipt record. This allows the AP team to verify not only the agreed price but also whether the billed quantities correspond to goods received or services confirmed.
For example, a business orders 100 units at $25 per unit. The purchase order value is $2,500. If the supplier invoices 100 units at the agreed price and the receipt confirms that all 100 units arrived, the core quantity and price checks agree. If the supplier instead invoices 110 units, the additional 10 units require investigation against the receipt and purchasing records before the invoice proceeds under company policy.
Service invoices may use service entry records, contract milestones, or authorized confirmations instead of physical goods receipts. The appropriate matching method should reflect the nature of the purchase and the evidence needed to support payment.
Matching Tolerances and Exception Handling
Matching tolerances define the differences an organization may accept between invoice values and supporting records. These rules can be expressed as percentages, fixed amounts, or quantity thresholds, depending on the system configuration and business policy.
Suppose a purchase order specifies a unit price of $100 and the company permits a 2% price variance. The permitted difference is $2 per unit, giving an upper comparison value of $102. An invoice price of $101 falls within that illustrative tolerance, while $104 exceeds it and requires the action specified by company policy. This example assumes the tolerance applies directly to the unit price and does not override other approval requirements.
Common matching exceptions include quantity differences, unexpected freight charges, price discrepancies, missing receipt records, and duplicate invoice references. AP teams should record the reason for each exception, identify the responsible buyer or approver, and retain supporting evidence for the final decision.
AP Invoice Matching Approval connects matching results with the authorization required to continue invoice processing. An exception may need an updated receipt, a corrected invoice, a purchase order amendment, or a documented approval under established policy.
Automation, Invoice Capture, and ERP Integration
Automated matching workflows can compare invoice information with purchase orders and receipt records, apply configured rules, and identify discrepancies for review. Invoice capture helps extract supplier names, invoice numbers, quantities, dates, and amounts from submitted documents, while validation checks prepare those values for comparison.
Invoice automation can connect extraction, matching, general ledger coding, approval routing, and posting readiness in a coordinated workflow. The goal is to move invoices with complete and consistent information through the configured process while directing exceptions to the appropriate team.

ERP integration is important because matching depends on reliable purchase order, receipt, supplier, and accounting data. Effective AP Automation Software can coordinate these activities while preserving transaction references and supporting a traceable review history.
Business Impact and Accounts Payable Controls
Consistent matching helps organizations validate supplier liabilities, apply purchasing policies, and maintain accurate accounting records. It also gives procurement and finance teams a shared basis for resolving discrepancies before payment. Strong procurement records support this process by preserving approved order details and receipt evidence.
After matching and the required approvals are complete, the invoice can move through the configured posting process. Accounts Payable Matching Approval describes the relationship between transaction verification and authorization, while Payment Approval governs the separate decision to release funds. Maintaining this distinction supports appropriate controls over both invoice liabilities and cash disbursements.
At month-end, the Accounts Payable balance should be reconciled with supplier statements and the general ledger. Finance teams should also identify received goods or services that have not yet been invoiced and assess whether accruals or goods received not invoiced (GRNI) entries are required. Accurate vendor management and timely payments planning help maintain reliable supplier records and support cash flow decisions.
Summary
Epicor AP Invoice Matching verifies supplier invoices against purchase orders, receipt records, and applicable transaction rules. Two-way and three-way matching support different purchasing scenarios, while tolerances and exception workflows determine how discrepancies are handled. By maintaining accurate source data, consistent approval controls, and effective automation, businesses can strengthen accounts payable accuracy, support financial reporting, and make informed payment decisions.
