It was helpful, but it only put the payers name on copy A, the other copies had all the information there, except the payers name, address, city,state, zip.......the main header.
Jerry
it has been easy to navigate.. but the price is still abit steep. I am student and I am using this one time for my paperwork. Hopefully you can have student packages.
Frances M
I love this application. I work extensively with government forms for skilled nursing facilities. So far your program is the best for making the forms look professional and for ease of use!
Becke W
in a nutshell: sooooooooooo much better than adobe acrobat. i'm a new user, but this was just infinitely less frustrating (and i'm hoping less expensive) that dealing with adobe.
Julieann P
What do you like best?
As a beginner, I was surprised not only with the fact that PDFfiller was so much easier to learn and use than the Adobe Suite but also at the range of capabilities on offer! From my first use of this online program I found new pleasure in dealing with .pdf files. I now use the program Every Single Day to create, manipulate or convert files that used to sit waiting, sometimes for days at a time, to be done by the one or two people with access to more expensive and less user friendly programs. Now I have a new "can-do" attitude to the workings of .pdf files. I can't recommend this online tool enough and it's so affordable, you can buy a license to use at home. Great product, lots of advantages. You will not look back, you will not regret this purchase.
What do you dislike?
The user Interface could do with being a little less busy. A streamlined interface and a compact "how to..." would take a 9/10 to a 10. It just needs some tweaking and it's perfect!
Recommendations to others considering the product:
In my opinion it is definitely worth spending the small amount to upgrade to the paid version!
What problems are you solving with the product? What benefits have you realized?
Administration issues generally...adding text, file conversion and commenting on documents...are all problems that I had to either pay to have done elsewhere or ask for an expensive subscription that was never in my budget and wouldn't be approved if I had asked.
Samantha Miller (Venezia)
THE BEST support team I have ever had, EVER!!!!!!! Best support team I have ever had. I used the dreaded "CHAT" where I usually end up banging my head against the wall. Today I chatted with Sam and I am dumbfounded how great things went! I can honestly say I have NEVER had the satisfaction that I got today! I can't even think of a chat before where I felt human afterwards. Today, I am gobsmacked how well everything went!Sam took care of what I was there for and did it with professionalism like I have NEVER experienced in a chat with a business!I can not say enough about this company! If Sam is an example of the company, which he is, then this is a 10 star company on a 4 star scale!
