I travel two weeks per month and that is a huge amount of time out of the office. Having the possibility to sign crucial documents while traveling is extremely important. It also provides the possibility to have all of them stored and available at one place provided by the application. You don't need extra storage on tour cloud or PC. Once signed, you share it or send it by email from within the application at the same step.

It is multi-platform, I can use it on my smart phone, tablet and personal computer. It also has storage for your signed documents, and of course, you can create folders to be accessed by co-signers.

Sharon

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.
