SaaS billing without a customer login

An ACH authorization link plus on-page terms. That is the product.

Private invite links

Send one URL per customer. It expires in seven days. They do not create a password.

Agreement on the same page

The terms open as a PDF beside the authorization. Clickwrap stays on the invite.

ACH authorization link

Stripe ACH collects the bank details. The charge matches the amount written on the invite.

You keep the operator seat

Customers pay. You send the next invite. No public self-serve signup and no extra login for them.
