Electronic Bank statements Italy

Dear experts,

In our Italian entity we have implemented the electronic bank statement, using the CBI format of the Italian bank.

In practice it appears that the matching rate of incoming payments is extremely low. Digging into the details of the bank file, it seems that very little useful information is available. In a few cases, customers mention the invoice number, which provides clearing information.

Does anyone have an idea to improve this reconciliation? Is there a possibility that the file contains IBAN information, based on which a customer could be identified?

Any input would be appreciated.

Regards,

M. Sportel
