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.
I understand that your JotForm is having incomplete payments and you want to clear them. You may delete the incomplete payment submission from the pending submissions.
You may be also interested in taking a look at PayPal Incomplete Payment FAQs for more information on this.
Hope this information helps!
