Just started to use this product and found it easy to start up and complete forms that were down loaded. I would recommend this product to others needing a simple but very capable pdf manager.

The log in process is a little clunky. I have not been able to copy paste a field in the template creator. I have 30 fields or so that will each have the same sized field, I should be able to duplicate the specific field a number of times and paste. No?

What do you like best?
I enjoy very much that I can scan in documents and then fill in and add things to them easily.
What do you dislike?
Very little. But sometimes I find I accidentally click on the up/down bar instead of the buttons. Also, some of the buttons are not intuitive, but trial and error works well, and mistakes are easily deleted.
What problems are you solving with the product? What benefits have you realized?
I used to need a type writer (or hand write) sometimes still to comply with using the forms given to me by the government. Now, I can upload them and use the computer. Much better.

Paul was fantastic Paul was fantastic. I have been chatting with several other people since April 3 and no one could figure this problem out. I was emailed that this issue had been referred to technical support and they could not provide adequate assistance. As I am not computer friendly, Paul was very helpful. He was very patient with me. I am extremely grateful to him for resolving this issue.

Very easy and intuitive, the learning curve is very small. Tiny differences in the drawing between what you see on the screen and in the printed document.

Go to Tool for pdf Editing Overall experience has been great ! This tool helps to merge, convert to pdf as well as edit pdfs as needed on the fly. The software has came in handy to sign documents electronically, quickly edit portions of pdf. Great tool for editing pdfs. I mean you could edit very little detail in the pdf and you wouldn't even know if it was changed. All in one package that gives tremendous flexibility with converting word documents to pdf, editing scanned images by converting them to pdfs as well as getting and authorizing with ability to get electronic signatures. With this software you don't need Docu Sign !! Cant erase back ground color for edited text. Edited text should appear seamless and not show signs of editing. Cursor movements and moving of text boxes needs alignment and calibration for more accuracy. There needs to be a way to revert back the changes done. Payment processing and charges need to be clear and upfront without any disguise.
