If financing is enabled on a sent estimate, on the Customer’s signing page they see a question, “How will you pay?” The options are “Pay in Full” and “Financing”. I think the "Pay in Full" language is limiting because you may offer 50% down/50% remainder or staggered payments. A better phrasing would be, “Do you want to use financing? Yes or no.” It accomplishes the same thing without confusing or misleading the customer’s payment terms if they don't want financing.
