    How to allow the user to fill the amount that he/she will pay?

    Asked by Brian on December 12, 2016 at 10:10 AM

    I sell service and not products. I need to set up a payment form that asks for an invoice # and lets the client fill in the dollar amount. Is there a mechanism to allow the client to fill in the amount they are sending?

    You can use a PayPal payment field in your form and you can change the payment type as "User Defined Amount" as you can see the screenshot below:

    So that, the user will be able to pay for the amount that he/she has entered.

    If you need further clarification, let us know.

    Thank you.
