An IBAN (International Bank Account Number) is a standard code that identifies one specific bank account. The European Central Bank's glossary describes it as an ISO code that expands the domestic account number and “uniquely identifies an individual account at a specific financial institution in a particular country”. Clients paying by bank transfer need it to send the money to the right account. On an invoice it goes in the payment details, usually below the total, together with the account holder's name exactly as the bank records it and the reference you want the client to quote. Example: “Pay to Studio Example B.V., IBAN NL00 BANK 0123 4567 89, reference INV-0231” (a placeholder, not a real account). Common mistakes: typing the IBAN by hand instead of copying it from your bank, and showing an account name that doesn't match the business name on the invoice, which makes careful clients stop and check. If you change accounts, tell clients directly rather than only printing the new IBAN on the next invoice.
