Has helped ease a lot of pain of having to have my clients sign documents

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.

What do you like best?

Easy to use and turn around times are great. I can get my client's signatures on documents in a matter of minutes. Previously to using airSlate SignNow, I had to wait for the clients to print out documents to sign and scan back to me. This was an issue because not everyone has a printer at home. airSlate SignNow has eliminated that issue. The time savings and turnaround time are by far the best feature. It's super easy to learn and use airSlate SignNow. I love how I can make templates and just make a copy for quick reference
