Using the templates is an awesome feature and makes sending all my onboarding documents easier. We use airSlate SignNow exclusively for signing contracts, agreements, and policies. All of our employees and vendors are familiar with it, which makes the process smooth.

I like how easy it is to set up a document, send the document and that the person receiving the document doesn't have to have an account or sign up for anything in order to sign it. I also like the notifications I get each step of the way. In the times we are in today, with everything basically paperless and electronic, this kind of a service is an absolute Must-Have.

airSlate SignNow - Effective and Affordable

Joseph

We were looking for a way to automate our lease signing process that was efficient, reasonably priced and legally binding. airSlate SignNow fulfilled these requirements for us and also lends a bit of credibility and professionalism to this process in the eyes of our clients.

airSlate SignNow is fairly easy to use. What I like most is that this software allows me to automate a process that used to take time and much effort. To get our commercial office leases signed, we either had to meet in person (a half a day's trip) with tenant or PDF documents, email them back and forth, print them out and re-scan for signatures. With airSlate SignNow, we can create documents to sign and store on their website. There is a trail of who has signed and who hasn't signed. No printing out or re-scan necessary. Just save PDF document to folder of choice when fully signed.

So far, airSlate SignNow has been exactly what we were looking for to expedite the signing process and everyone who has signed, has said it's been really easy! We have much more thorough contracts now, because fields are required to complete and we get all the info we need.

I think airSlate SignNow is more aesthetically pleasing and easier to use than other similar programs I have tried. The price is great and I love have lots of different templates I can save and use, and that airSlate SignNow stores all my signed documents as well as giving them to me in PDF
