How would you like to consider embedding the form that you will create in JotForm on your website that is on your own domain? You may collect orders and process payment within your form using any of our payment processing apps.

But, if you really need to use your own domain for the direct link to your form, you must have an Enterprise type of account with JotForm as stated in the guide.

Feel free to let us know if you need any further assistance.
