    When using Authorize.net, how do Is et it up to let the customer enter the amount that they want to pay and then add on a 5% service fee or tax? I'd like to use my authorize.net account to collect invoice payments and absolutely love the ease of use of your program. Thanks in advance for any help, Damon

    You can let users enter their own amounts using "Donation" option on the payment wizard.

    However, JotForm cannot calculate service fee or tax.
