Makes things easier when it comes to signing

With airSlate SignNow we save time and money. The documents can be signed in a much shorter time and you don't have to pay for sending them. Of course, you pay if you take the package but it is nothing compared to how much you get when you have to send it by post. Plus, in some countries, you have the surprise of not getting the mail at all or getting it too late.

We just started to use this software. I like how easy it is to sign documents! We have coworkers in different countries and this software saves time and money. We are now using the free trial, but for sure we will buy the package.

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

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.
