Can I create an approval workflow using JotForm?

I know there is a signature tool in the form creator, but is there a way to be able to send an approval form to someone to sign?

This would be an individual client and would be many different people and not a set list.

I'm sorry, but I don't fully understand your question.

From what I see in your form, I think that you're referring to an approval workflow. If this is the case, you can check the steps provided by my colleague here: http://www.jotform.com/answers/401633#401648 to see how can this be done.

Please check it out and let us know if this could be a viable solution for you.
Thanks.
