How to enable users to continue the forms to complete later?

Does Jotform allow customers to return to a form to complete at a later date? 

In other words, can a client begin a form and return later and pick up where they left off without losing any data? 

Thank you!

Yes. It is possible to come back later and fill the form later by enabling Auto-Fill option from the Form Preferences.

Please refer to the guide below that can help you in this regard.

Please note that this method works only when the user accesses the form from the same device using the same browser since the data is stored in the browser storage. If you want to enable your users to continue later on different browsers or locations, you may consider using session parameter method as mentioned in the guide below:
