Hi

We added this into the report by overwriting the report.external_layout_footer:

"<t t-foreach="company.partner_id.bank_ids" t-as="bank">

<ul>

<li><span t-field="bank.bank_name"/></li>

<li>BIC/SWIFT: <span t-field="bank.bank_bic"/></li>

<li>IBAN: <span t-field="bank.acc_number"/></li>

</ul>

</t>"

This will output every single bank account created and display name, BIC and IBAN / Account number.

Remember to set the option "show on invoice" in the bank accounts.
