A lot of my customers pay by EFT (direct Deposit), while I have configured my EFT details within the Footer of the Invocie the customer can't mark the invoice as paid within the customer Portal.
This is then requiring my customers to make contact with me outside of the customer portal (email/Phone) and i then need to manually go in and record the payment within the admin portal. This completely negates the benefit of the customer portal, and in fact actually makes my customer not want to use it.
I am not looking for integration to anything, simply an option the customer can select that marks the invoice as paid.
