How Costpoint Three-Way Match Works
The process normally starts with a purchase order that establishes what the organization agreed to buy. When goods or services are received, the receiving transaction provides evidence of what was delivered. The supplier invoice then supplies the amount requested for payment.
Costpoint Three-Way Match compares relevant fields across these records. A successful match generally indicates that the invoiced quantity is supported by receiving activity and that pricing agrees with the authorized purchase order. Exceptions can be routed for review when values fall outside established tolerance rules.
The broader concept is explained by Three Way Match, which applies the same purchase-order, receipt, and invoice comparison principle across finance and business workflows.
Core Matching Components
Each component contributes different evidence to the validation process. The purchase order establishes authorization, the receipt establishes delivery, and the invoice establishes the supplier's billing request.
- Purchase order: Provides ordered items, quantities, prices, supplier information, and purchasing terms.
- Receiving record: Shows the quantities or services recorded as received by the organization.
- Supplier invoice: Provides the billed quantities, prices, taxes, totals, and invoice identification.
- Matching rules: Determine which fields must agree and which differences can be accepted within configured tolerances.
For procurement teams, Three Way Match Procurement highlights how matching connects purchasing controls with invoice validation and payment authorization.
Three-Way Versus Two-Way Matching
Three-way matching introduces receiving information into the validation process, while two-way matching primarily compares the invoice with the purchase order. The appropriate approach depends on the nature of the purchase, receiving requirements, and internal controls.
2 Way Matching can compare invoice and purchase-order data when receipt confirmation is not required for a particular transaction. By contrast, 3 Way Matching uses purchase-order, receipt, and invoice information when delivery evidence is an important part of the control.
The guide Master AP Matching: 2-Way, 3-Way & No-Match Explained provides additional context on how these matching methods differ and when each approach can support invoice-processing controls.
Configuration and Exception Handling
Matching rules should reflect the organization's purchasing policies and the types of transactions being processed. Matching Startegy Configuration supports configuring three-way, two-way, or no-match approaches according to factors such as vendor or expense category.
When a transaction does not satisfy the configured conditions, the exception should be reviewed against the supporting records. Common exceptions include invoice quantities exceeding received quantities, invoice prices differing from purchase-order prices, missing receipts, or invoices associated with an incorrect purchase order.
An Exact Match represents a situation where the relevant comparison values agree exactly according to the matching criteria. Tolerance-based matching can instead accommodate approved differences where organizational policy permits them.
Role in AP and Procurement Controls
Three-way matching is closely connected to the broader procure-to-pay process. Procurement teams establish purchasing requirements, suppliers fulfill orders, receiving teams record deliveries, and AP teams validate invoices before payment. The concept of 3-way match is therefore particularly relevant to procurement controls, purchase-order approvals, receiving, and spend visibility.
Matching can also begin before an invoice reaches the final approval stage. Vendor On Boarding can use two-way or three-way comparisons of W-9 forms, contracts, and system records to establish reliable vendor information, while Vendor Identity Verification can compare vendor documentation and external information to validate supplier identity.
For invoice workflows, accurate source data is essential. Matching can be supported by structured invoice extraction, validation, and coding, including appropriate chart of accounts information before posting to the general ledger.
Automation and Operational Efficiency
Automation can coordinate invoice capture, field extraction, purchase-order comparison, receipt validation, exception routing, and approval. This creates a consistent workflow for organizations processing large volumes of supplier invoices while preserving review points for transactions that require human attention.
When three-way matching is embedded into broader AP workflows, finance teams can connect purchasing evidence with invoice approval and downstream payment processing. This supports stronger transaction accuracy, clearer audit documentation, and more consistent financial reporting.
Summary
Costpoint Three-Way Match compares purchase orders, receiving records, and supplier invoices to validate that billed goods or services were authorized, received, and invoiced according to applicable terms. By combining matching rules, tolerance handling, vendor controls, and AP approval workflows, organizations can strengthen procure-to-pay controls and improve invoice accuracy before posting and payment.
