Hi,

The items displayed on the invoice are specified in the report_invoice_document template from the account module: https://github.com/odoo/odoo/blob/17.0/addons/account/views/report_invoice.xml. 

So you would need to extend this template to add your account details.

<template id="invoice_report_view_bank_details" inherit_id="account.report_invoice_document">

<xpath expr="//div[hasclass('clearfix')]" position="after">

<dl id="bank_account" t-foreach="doc.company_id.bank_ids" t-as="ba" class="dl-horizontal text-muted">

<dt>Bank:</dt>

<dd><span t-field="ba.bank_id.name"/></dd>

  </dl>

</xpath>

</template>

Regards
