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.

SignNow Customer

All things considered, airSlate SignNow is very much worth it for the value it provides for the price.

airSlate SignNow has been an invaluable tool for me in my efforts of making my work time more efficient by focusing on actual work. It has been a great tool for my team and I, as we now have a centralized platform to take care of our signature needs when working on things that require a client's or a coworker's signature. It saves us a lot of time this way. The interface itself is intuitive and is easy to use. Another great thing about airSlate SignNow is that it offers various pre-built templates, which we don't often use, but they are still there for us when we need them.
