You will assign an unique IBAN code to every partner or to each payment obligation, which will be indicated on the payment documents (invoice, payment notice etc) as the IBAN in which the customer has to pay.

The unique IBAN will contain useful information for reconciling collections, such as a customer code in your accounting system.

Once the amounts have been collected, the bank will provide you with the beneficiary IBAN, allowing you to assign the funds with 100% accuracy.

This solution is applicable both to collections made through payment order, as well as to those made in cash.
