So far I have only used it to print the current W2 forms for my employees but it has been really convient. I like the numerous ways you can fill our forms and love the signature features. So far, so good.
Jennifer
Great, just unfamiliar with how to align the form instead of having to align each individual letter. Cannot believe this is correct. Otherwise love the look and professional appearance.
Sandi G
It is impossible of find the document I am seeking and all I am getting is a WASTE OF MY TIME!!! The website is incredibly difficult to navigate!!!!! I don't think I am getting much value for the money I spent to print just one document!!! After this horrible experience SUPPORT STAFF was able to assist me in accessing the necessary document and getting it filled out to me the deadline. SUPPORT STAFF is very knowledgeable and were able to resolve the problem quickly!!! Count me a happy customer!!!

The application i sy to use and functions very well. I have had no issues with the app. Would like to know what "Host a Fillable Form"s. Opens an "Employment Agreement" when I click on it.
J C McColman
The software if very intuitive. No wasted time trying to figure out how to use the software. Not having to update the software periodically or pay high Adobe license costs. Drag & drop features and drop down menus work flawlessly. I can have a colleague use the software and not have to explain how to use it. May be thatI haven't had time to really look at this, but I find that I have a lot of information in my main folder. Intuitive or simple organization structure would be nice. I'm usually in and out of there to get what I need done, but I did have to search a few times and thought I needed to clean up that home screen.
