What do you like best?

You can use it on the go with the app and it works great to sign contracts and get a quick response. Very easy to use for unfamiliar users. Simple step by step instructions that are easy to follow for anyone. Ability to add text to the document along with your own signature is very helpful and gives you the ability to edit the document as needed with starting over. I like the fact that it emails you the document when finished and also every time a signature has been collected so that you are up to date at all time. You have the ability to download or upload to Google Drive as well. Template abilities and options help save time and allows you to send documents right after another to numerous signers.
