Hi
Ues this works on whatever payment method you use. The buyer will get a invoice and its up to him how he pays. If you do not want Paypal, then make sure that you remove it from your "my details " page.
If you want to accept PPPay, then make sure that your account details are again in your "my details".
When you combine the invoice you are given a box for you to add your own comments, which the buyer will see when he gets the invoice.
