So far it has been user friendly. I am sure it can do a lot more than what I am doing right now but I am learning more as I go a long. I think a webinar would be very helpful

I was allowed a 2 week free trial following an online chat about the product. I was so impressed with the features that I purchased an annual subscription! Very user friendly! Great customer service via chat.

I just wanted to fill one document but I don't have full adobe on this machine. Then I wanted to print and I had to buy it to print which was okay as I need a system. It works great now that I am learning how it flows.

I was looking for an app that will convert a sensitive file that has security feature that only the user or the owner of the file will only see it after it was being edited.

I am happy with how to fill out the health claim form template. It is user-friendly and reliable. It is a little slow to open documents and I waste some time looking for the right one. I don't like the organization system and I haven't figured out Templates. I am not looking for a practice management system so I like buying only what I need. Overall, I like the app and I paid for a year subscription.

pdfFiller you need this!
I have had nothing but an easy time with this software. It helps me daily with all my forms I need to either add or change something on. It is truly worth the price. Once you get it you will not know how you lived with out it.
I like the ability to edit any PDF document edit it, change it and or recreate it.
I truly have not found any issues with this software it just works.

It would help to have some sort of tutorial outlining the all the functions. Having been offered a webinar during the 30 day free trial would've been helpful.
