Getting paid

Payment reference

A payment reference is the identifier or message a customer includes with a bank transfer or other payment so the seller can match the money to the correct invoice or account. It may reuse the invoice number or follow a banking scheme. The required format should be copied exactly because some references include validation digits.

Why this matters when you invoice

A reliable payment reference reduces manual matching and helps prevent a received payment from remaining unidentified or being applied to the wrong invoice.

Where it appears on an invoice

Place it beside the bank account or payment instructions. Tell the customer exactly what to enter and distinguish it from the invoice number when the values differ.

Worked example

Payment reference example

Invoice IC-1042 asks the customer to enter RF18 5390 0754 7034 as the transfer reference. When the payment arrives, the seller uses that reference to match it to the invoice.

Common mistakes

  • Confusing the reference with the IBAN or account number.
  • Changing a reference that contains check digits.
  • Providing several possible references without saying which one to use.

Put it into practice

Frequently asked questions

Can the invoice number be the payment reference?

Yes, when the payment method accepts free text and the seller's process uses invoice numbers for matching.

Is a payment reference the same as an IBAN?

No. The IBAN identifies the bank account; the payment reference helps identify the invoice or purpose of the transfer.
