I had trouble with saving files but I figured it out. The program comes with alot of different features and a webinar to see how it all works would be great.

Very useful service. Trying to create a fillable pdf is made simple. Although when it's downloaded, one or two areas are not fillable anymore so have to do it again.

What do you like best?
I have been using PDFfiler for more than 4 years. It makes my pdf documents look professional. There is no longer a need to print a doc, fill it in with pen, scan, and send. PDFfiler reduces the amount of steps I have to take to get the job done. It helps to also have everything saved on the My Docs page. I can find the same tax documents I need month after month. PDFfiler also reduces the amount of paper needed to generate a document. I probably use PDFfiler every day.
What do you dislike?
I would like to be able to turn off the assisted pop-ups. They can obstruct the box I want to enter text.
Recommendations to others considering the product:
Simple to use. Makes your docs look professional and neat. Easy to manipulate a doc that is incorrect.
What problems are you solving with the product? What benefits have you realized?
I fill out every form on PDFfiler. It's automatic to me. In addition, when I am unable to edit a Word doc or other pdf, I know I can upload it to PDFfiler and get the job done right away.

Few years with pdffiller I am their client for almost 3 years. I did my best to get how it works and was making bad reviews in appstore because complicated ui on the start. I was checking out competiting editors, but I could say that other apps were even more complicated. Many things changed from that time and editor became much more user friendly, got new options for saving money and time. I am less about challenging their customer service but sometimes updates are a bit confusing.

Very user friendly! It is easy to use. Instructions are clear and the forms are easy to fill out accurately. I only use it once a year - at tax time, but using this program to fill out tax forms is quick and easy. I have not had any issues. I'm sure if a person uses it a lot there are bound to be some, but I use it once a year and it works fine for my uses.

A great Program Its a good program, but it takes a few minutes to get use to the actual text placement for your fill in. I did not try the signature feature. I will continue to use this program. I'll use it more often as I get use to it.

Was looking for something more physical… Was looking for something more physical therapy specific with the super bill, had to create my own. But otherwise this was very easy to use.

Just started using it . Too early, but looks Good! 10/2/2020 I have been using PDFfiller and it is great! I am using my own PDF forms, therefore, I would rather browse the files on my computer rather drag and drop. But this is a personal preference. The drag and drop does work. I am using it to prepare and send contracts to customers and it is well accepted. I have attempted to do this with other popular word processing and spreadsheets and they are very complicated and don't work for me. I like PDFfiller very much.
