Very easy system to use and user… Very easy system to use and user friendly. The only suggestion I would make is being able to scan documents and then being able to combine them into 1 pdf file not having it as a zip file.

Honest business practices Like many other online products, they make it VERY easy to sign up, and not so easy to cancel. But once I found the correct place, they did allow me to cancel and refunded my money quickly. While the product did not fit my needs, the company appears to be legitimate and honest.
