Hello Stephane Kolijn,

You need to inherit odoo's standard qweb report of invoice i.e report_invoice_document. You also need to configure Online Bank for Invoice Journal.
Once you set-up Account number in journal(Customer Invoices) you will be able to print in invoice report. Please find syntax to print it.

<template id="report_invoice_document_inherit" inherit_id="account.report_invoice_document">
<xpath expr="//div[@name='invoice_date']" position="after">
<div class="col-auto col-3 mw-100 mb-2" t-if="o.journal_id.bank_acc_number" name="bank_acc_number">
<strong>Invoice Date:</strong>
<p class="m-0" t-field="o.journal_id.bank_acc_number"/>
</div>
</xpath
</template>

Thanks & Regards,
