Efficient, accurate, and secure, that’s what proper invoice matching delivers. At Documation, we specialise in automating the 3‑Way Matching process, the backbone of sound procure‑to‑pay operations. By aligning the Purchase Order, Goods Received Note, and Invoice, businesses eliminate costly mistakes, reduce fraud, maintain audit readiness, and free up valuable time for strategic work.
Discover how our AP Automation Solution makes this process seamless, transparent, and responsive, helping you keep payments flowing smoothly, suppliers happy, and your bottom line protected.
Eliminates Fraud
Purchase orders are created in line with business rules, and many companies have a No PO No Pay policy. They follow an approval process to ensure the business need, approved supplier, and budget allowance. Matching an approved purchase order with a GRN and invoice prevents paying for undelivered goods/services and minimises unethical employees colluding with suppliers for fraudulent gain.
Accurate Tracking of Supplies
Knowledge of goods ordered, delivery & settlement dates makes it easy to see what has been delivered, and paid for. If there is a dispute over an invoice having this transparency makes it easier if it comes to litigation.
Saving Costs & Increasing Profits
It is easier to keep track of goods ordered, price differences for the same goods from multiple suppliers, late deliveries, part shipments, etc, enabling the procurement team to be more agile with ordering and more effective at cost saving.
Auditing
When auditors require supporting documents for payments, having the GRN and PO available to back up the payments made not only makes the process quicker and provides full visibility of the audit trail, but also shows transparency.

Benefits of AP Automation Solutions
Documation has a full AP Automation Solution that automates 3-way matching to give your team time for more value-added tasks. You can download our datasheet or find out how our solution can help you with your automated invoice processing by getting in touch with our listening team.
Saving Employee Time
No more manual verification of detail, often time-consuming line detail, on GRN/PO/Invoice, leading to human error. Automation means quick, accurate matching with match exceptions routed to the relevant department and flagged for manual matching.
Improving Supplier Relations
Automated 3-way matching can happen within minutes of an invoice arriving at the business, allowing suppliers to get paid on time. Workflows give full visibility of the invoice, match discrepancies and show where the invoice is in the business process.
Protect against fraud
The automated 3-way matching process means all orders must have a PO and a GRN. POs are created within business rules and are authorised outside of the AP team, giving segregation of duties at source and helping to eliminate internal fraud. Invoices for goods that have never been delivered will not slip through for payment, meaning no speculative fraud attempts.
Audit Ready
Automated 3-way matching has all documents available digitally, and therefore will not hold up your AP team when the auditors request supporting documentation for payments made. Full audit trails and visibility of orders, goods received, and invoices are available at any time.
Early payment Discounts
Being able to process invoices for payment within minutes of arrival opens up opportunities to negotiate early payment discounts.
No more duplicate payments
Duplicate invoices are rejected on arrival and never added to the system for payment.
