For paid plans can we use our own domain URL?Asked by taxnetfinancial on August 25, 2014 at 06:11 PM
You can map your custom domain name with your form URL (available for free or paid). Here's a full guidehttp://www.jotform.com/help/144-How-to-use-Custom-Domains-with-Jotform.
Another alternative solution is to take your full source code and upload it to your server.http://www.jotform.com/help/104-How-to-get-the-Full-Source-Code-of-your-Form
