Overall easy to use, however, there are instances where the edits on the pdf become warped, other times its difficult to remove words or characters. There should be a save option versus a Save As, as that navigates you to another screen. Or have an auto save option. Overall good program but still has small defects.

AISYAH MOHAMED
I like having this resource as an option. I like that it offers a clean, crisp look for documents. The forms or finished forms look very neat when they are typed. It seems like a great option for persons to use when their handwriting is not legible. The words do not stay within the lines. I used the software recently and the office manager had to retype the form because the words did not fit.
Dr. Debra K.
First time user First time user. It was fast and easy to learn. I hate doing govt forms and this was so simple to use and completed what takes me hours in mionutes.
Richard J Doulette
What do you like best? I use the pdf merge feature constantly. It's great for compiling packets, assorted documents, expense reports etc. What do you dislike? It's not cheap, limited to uploading 5 docs What problems are you solving with the product? What benefits have you realized? Compiling meeting materials. Digital signatures.

So far, it has been acceptable, but I am having to self teach a lot of items. It would be good to have a one hour presentation on the basics, and then some specific presentations on individual task.
Terry H
I had an issue and emailed the company and not only did 2 different people respond immediately they resolved my issue within a few hours of me sending the email. I’ve never seen that quick of a response before. Very impressive.
Rob K
Completed what I needed done Completed what I needed done. The reason for 4 stars is because you force people to sign up for a monthly subscription versus just charging for the one time use of the feature.
