We have solved the issue of "how do we get contracts to and from clients as easily as possible". Now clients don't have to worry about printing and signing contracts and then either mailing them or scanning/emailing them. This software is simple for them to use. The Guide function allows them to easily fill in the required information and submit it to us.

The airSlate SignNow software is easy to use. From uploading documents to filling in text responses, signatures and specialty form boxes, this software is simple and intuitive. Our clients love the option of online, digital contracts and forms. It is easy for them to fill out and send back to us, complete with an electronic signature.

When I started my business, I needed to find a digital signing solution for a low cost... so even though I had never heard of this program, I decided to give it a try instead of using one of the more well-known digital signing programs. My business is small, and I don't need digital signing on a daily basis. So, the lower price very much attracted me. And ultimately, I'm very glad I gave it a shot. It has definitely met my needs and is affordable. Also, there was one occasion when I needed to contact customer service because I changed my e-mail address, which caused a billing error. I sent an email to customer service, and the issue was resolved very promptly and easily.

The program is quite easy to use and navigate. And it appears my clients find it easy to use as well. I've never had any complaints or questions from them.

In my rental property business, I need to have all tenants for each property complete and sign about 8-10 lease documents. airSlate SignNow allows me to create the documents in Microsoft Word with text tags, create conditional fields, custom routing, and signature expiration dates, automatic reminders, etc. airSlate SignNow allows me to process these documents remotely and without paper.

Ability to create documents in Microsoft Word using text tags to automatically transform them into fillable templates when I upload the documents. I can then create document groups and custom signing order, which works great for signing real estate property leases.
