Taylor Soltau

What do you like best?

I like that we have the option to either e-mail or text over a link for the customer to click on and allow them to sign documents on the go. I also like that we can put a multitude of documents up and combine them into one. It makes it easy to send over one document for the client instead of having to send a lot of different ones and wasting their time.
