I've been using Adobe for all my PSF editing needs, but this program is so much easier and faster, I can't believe I wasted my time and $ on Adobe for way too long! so glad I found this program!

Fabulous addition for the office!!… We added this for our company in the office as a tool to try out and make things easier. Honestly I have used it far more than I thought. No more printing out anything to fill out and sign it and then scan it back and send it. You can upload and fill in the spaces, check any boxes and sign it, save it and email it right over, and it looks so much more professional too.

BEST all-in-one Platform for business and personal use!!! I am in LOVE with this app!! This platform provides an all-in-one service for a price you just cant beat. Without a doubt the #1 MUST-HAVE business tool that trumps all the rest. They even offer Monthly or Annually subscriptions giving the user some flexibility pricing to choose what suits them best based on their individual or professional needs. Absolutely worth every penny!!

New to this software but appears to be want I needed working with the many aspects of PDF's for our website. PDF Filler offered an excellent annual rate. I am concerned a little about getting to involved with them. You see it happen often after one year with service providers the rates start increasing. Than you need to find a new service to merge your existing business with. We'll see. Overall though the company has been excellent.

It is a great tool that anybody can use. It does not matter what type of business, school, or type of work you do you will get out of this service if you have to continually deal with PDF documents. Do you need to sign something? Check. Do you need to change a shipping label by a major retailer for a return? check. Tax documents? check. For real, I'm just a regular stay at home dad and I use this AT LEAST twice a month.

There are some minor things I have not figured out how to do. Not sure yet if they are just missing features, or just not readily available in a way that I was expecting.
