See for yourself by reading reviews on the most popular resources:
I did not know there was a charge for using this until I got to the very end. I had spent too much time filling out the form to end and start over. I want to cancel at the end of one month.

Great product. Made tax time for my small business EASY and COST EFFECTIVE. I did my own tax documents and saved HUNDREDS of dollars the first time I used it because I didn't have to pay an attorney to do these simple forms.

I was a little confused when I first began using the app, but did an online chat with their agent who walked me through what I needed to know. Therefore; I would recommend this subscription to any Commercial Insurance Agent who issues multiple Acord forms.

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.

I only needed it for one purpose, to make my client's insurance claim sheets a fillable form so I wouldn't have to freehand it. After the initial struggle to get it structured right it works wonderfully

Easy process and good program with a nice free trial, just not able to fit in my budget.
Easy process, user-friendly, quick and efficient. I like that it let me trial it for a few days. I just don't have the money for a subscription right now and only needed to use it this one time.
