Is there a way for the person completing the form to save it and submit later?

Hello kristilee1226,

Yes it is possible to achieve your requirement. There are multiple options available:

1. Auto Fill feature:  You can enable the "Auto Fill" feature of your form which will save the input data every few seconds. Please be noted that auto fill feature saves the input data in browser cookie. That means if the user access the form again from other browser, other system or clear the browser cache, the saved data will not be accessible. The following guide should help you:  http://www.jotform.com/help/227-How-to-Enable-Auto-Fill-Feature-Save-Form-Entries-to-Continue-Later 

2. Save input data in session: User can save the input data in session that is stored in our server. Please be noted that this feature requires two forms and the main form should have the "Page Break" field. The data is saved only on the click of the next button. The following guide should help you:  http://www.jotform.com/features/save-and-continue/ 

3. Edit Link: You can add the {edit-link} tag in the autoresponder email alert of your form. When the user submit the form, they will receive the email which will have a clickable link. Click on this link will allow the users to edit the submission data again.
