See for yourself by reading reviews on the most popular resources:
Impressive features and easy to use. My only gripe is that there appears to be no way of changing the date function to day/month/year, but it's just as easy to enter the date manually

Tree saver
My son has to do virtual school with everything going on at the moment. This is great for filling out worksheets instead of printing and killing trees

Useful form creation and library tools
Makes confirming client changes and work ideas more fluid with notifications of form signing. Wide tool set and excellent selection of preexisting forms.
So many forms and flexibility to edit and create and cross share forms with clients, and the addition of the iOS app makes for a great always on solution and current information.
Price is ok, for single users but for larger firms it may be a consideration. So far no other issues

Bravo!
I was just on the phone and wrote back to congratulate the customer service rep on my call. I was very nervous about making sure my document was sent properly because a 5 year deal is riding on it. She helped calm me and understand things were handled properly. Bravo!

VERY EASY TO USE PLUS ONE SUGGESTION
VERY EASY TO USE. THE ONLY THING I THINK NEEDS TO CHANGE IS THAT WHEN I SAVE THE DOCUMENT, INSTEAD OF SAYING IRS FORM 940 (OR SOMETHING CLOSE TO THAT) I THINK THE YEAR OF THE FORM THAT WAS WORKED ON. FOR EXAMPLE: IRS FORM 940 2019

Great program for the price. I save many documents as PDF's and there ar times when one word or sentence needs to be changed. It is so simple, open the doc, make the correction and save,

Most of our Company Documents are…
Most of our Company Documents are shared in .pdf format so having the ability of edit them without the need to print out and then fill them in is my reason for the 5 star rating. The interface is simple to understand and easy to navigate.
