See for yourself by reading reviews on the most popular resources:
i thought this was going to cost me 20 or $30. instead my visa showed a $70+ bill. this is not what i signed up for? feel free to contact me and let me know why the extra cost.

I changed my review because of excellent customer service. I had issues with the product that made the program unusable for me and was not happy with the cost. A representative contacted me right away and refunded my money before I could even ask. For that, I am truly appreciative and wish more companies would follow their example.
2015-10-19
PDFfiller is a good value application for PDF file editing, filling and file management. My limited use of the application so far leaves a lot of its functionality to be discovered. However, it is very user friendly and simple to work with.

Very professional, highly recommended.
I needed to create some fillable PDFs for a course I'm running and PDFfiller allowed me to do that with ease. I needed a bit of guidance on how to do it from their person in the chat box (who was very helpful and efficient) and, once they showed me what to do (it was easy), the software was great and pretty intuitive and allowed me to create fillable boxes neatly and easily - it gives you guidelines so you can line them up with each other. It's a pity they don't do a "one-off" fee of $5 or something, rather than a subscription because it's not something I need regularly, so I'd have been happy to just pay a little something toward using it, rather than signing up for the 30 day free trial. Highly recommended. Very professional. Lisa Cherry Beaumont of LisaCherryBeaumont.com

Must Have!
This program is awesome for creating new contracts or clients, you can even email it and have them sign online.
It automatically charges you for a year so make sure you choose monthly billing if you would like to be billed differently than annual.

The number of hours that I was browsing…
The number of hours that I was browsing the site and the features I am more than satisfied and would recommend anyone who wants to have a higher PDF filler easy to use and a professional look is plus.

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.
