How to send an invoice with an attachment for customer to pay and also sign a credit card authorization form?
I currently run a utility/car hauler trailer rental company. I have paper forms and a chip reader for payments now. However I would like to speed up and simplify my processes. I know how to send invoices to customers but how do I go about adding a way to get all of there card information and an authorization form (states I can charge the customer for late fees an damages) into the invoice. Id like to add the rental agreement also.
