JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
If you want your user to directly input their payment directly onto the form, you can try to use Paypal Pro. You can check this article for further information regarding Paypal Pro: Difference Between PayPal and PayPal Pro. It is also possible to do the same on Authorize.net.
Do inform us if you need further assistance,
