So we had been looking for a online document signing software for our equipment rental company. we had a couple criteria, first was the ability to have the cudtomer upload a picture of their ID and Proof of insurance to verify their Identity. Also we needed it to be legally binding, and for it to be reasonably priced as we are still pretty small and rentals are only a portion of our revenue and wouldn't justify a month subscription some of the other software we looking at had. This fit the bill and more. Glad we switched.

The ability to sign forms even when I am not in the office which is quite often due to all the work I do in the field.

I have been using the system for over a year now. It allows me to conduct business no matter if I am in the office or not. I have to sign medical consent forms for my clients and this allows me to do so no matter where I am. I use both the mobile app and the online desktop version.
