I love that I am able to correct and hold prior to sending out my file for signature. I wish I could however have a authorization statement from the Calyx Point file to use more of there forms.

This program is very useful for filling out tax forms. Although my returns are not complicated, getting the credit that I am due for foreign taxes is too much for tax programs like HR Block and too much for most accountants. I have returned to my old habit of doing my returns manually. This PDFfiller program makes it feasible.

I'm a noob when it comes to computers, but this app helps me and I have been able to complete the court doc's I need to get $ back from my Ex. That's something I would not have been able to do without PDFfiller. Awesome app. David B Roseville Ca

Simple and powerful to use to edit, sign and reorganise pages quickly thanks to its web interface.
For me, it is a must-have and is reasonably priced compared to its competitors.

What do you like best?
What I like best is that I can upload my documents. I then edit them as needed. I can print, save, and fax all from within the application. The system is user-friendly and easy to navigate.
What do you dislike?
I cannot pinpoint one thing that I dislike. I use this application regularly. It fits all my day-to-day needs, whether that is business or personal. The fee for business users could have a certain percentage off.
What problems is the product solving and how is that benefiting you?
There is a lot of signing documents in the business I work in. With this application, instead of printing the paper, singing it, scanning it back into the computer, then exporting it where it needs to go. I can sign via text and, from there, can ship where it needs to go.

THIS THING IS A DREAM (although I did have some kind of issue opening up a file.) I used the MERGE function and it merged some files I didn't need. That was weird. So I'm editing one page at a time instead. That seems to be working.
