I would like an answer to this too.

Thank you Ray! I looked at that post previously and it worked for Authorize.net. Unfortunately for Stripe the button form is different and has nothing to do with the authorize.net configuration. Besides the order and billing information it loads this script, seems to me that this script needs to be modified to allow ACH Payments.

<script
type="text/javascript">

odoo.define(function (require)
{

var ajax =
require('web.ajax');

            ajax.loadJS("/payment_stripe/static/src/js/stripe.js");

       });

 </script>

I'm not sure, but did you see the updates to the Question at https://www.odoo.com/forum/help-1/question/how-to-accept-payments-through-ach-automated-clearing-house-93622

It does mention Authorize.net, but I wonder if the advice about modifying the architecture field applies to Stripe also.
