Candice Anderson

What do you like best?

Before using airSlate SignNow, I had worked with one other eSign program, so I am no expert by any means. What I liked best about airSlate SignNow, is it was very easy to jump right into using. We are a small business and primarily use it to have new sales partners sign their agreements, payment schedules, etc. It was easy to add a combined agreement and insert text, date, and signature fields. I also like that it provides a link and an embed code depending on your version you purchase.
