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 what you wish is to add a field for paying, yes. You can add a form to collect payments on your form. You can make use of either product purchases, subscriptions, or custom payments / donations. One of the payment gateways available at your disposal is Paypal. Simply get the Paypal payment tool element from the left panel and continue filling up your Paypal information and add your products in it.
You may read on further on this user guide to learn more about receiving payments with your forms: https://www.jotform.com/help/47-Order-Form-Basics
