Buyer Reference

What is a buyer reference?

A buyer reference (often called "Buyer's Reference" or "Person Reference") is a unique identification code added to an invoice to ensure it can be automatically routed to the correct approver in the recipient's organization. In complex companies with many departments, the reference acts as the "name tag" that tells the accounting system who is responsible for approving the expense.

How it works

When an employee makes a purchase, they provide their personal reference (e.g., initials, an employee ID, or a specific project code) to the supplier. When sending an e-invoice, this code is placed in a specific field in the XML file (in Peppol/UBL, this is typically the cbc:BuyerReference field). When the recipient's system imports the invoice, it reads the reference and automatically sends the invoice directly into that employee's digital approval workflow.

The need for precision

For automation to work, the reference must be 100% accurate. If the supplier mistypes the reference or places it in the wrong field (e.g., in a free-text comment field rather than the dedicated reference field), the recipient's system will fail to recognize it. This results in "manual exception handling," where a bookkeeper must manually track down the right person, significantly delaying the process.

Integration and validation

Modern invoicing platforms can be configured to validate buyer references before they are sent. By matching the reference against a list of approved codes provided by the buyer, the system can reject the invoice at the source if the reference is missing or incorrect. This ensures a very high degree of Straight-Through Processing (STP), where invoices flow through the system without any human touch.
