I thought this would be to costly per mo. for my use. When I went to cancel I was offered a 75% discount to stay for another yr. That will certainly give me time to see its use.

This program has allowed us to reduce the amount of time it was taking to complete our main work task by at least 50%. The only significant improvement that would increase our experience would be the ability to rotate any specific text input by 90 degrees.

Mostly I am thrilled with this service I didn't know I needed... until this week... and I needed it twice!! The form MC 030 was glitchy when it came to cut and pasting and editing the comments section. My only complaint.
Teresa K
I really enjoy how user friendly the program is. If I had any complaints, it would be that I have to change the size of the font if I am updating a previous document that I edit.
Sherri R

I needed Form W-2c and fast. I looked online and this was the first link I checked. I was super happy with what I saw I could do. I'm glad i found pdfFiller for my urgent document needs!
Nicole L
Excellent programme Excellent programme, does exactly what you need it to. I'm very satisfied with it.The only reason I didn't rank it 5 stars, was because it is slightly slow to use, in that there are a lot of buttons and windows.It could be made to be more intuitive, and more straightforward.But nevertheless, it does do what I need! So no complaints.

What do you like best? The tools are easy to find in PDF filler. What do you dislike? It is sometimes difficult to execute certain tasks when the pre-highlighted boxes appear. What problems are you solving with the product? What benefits have you realized? I have learned how to use it better, which has negated some of the issues. It is a helpful tool for a job that requires me to fill out many PDF documents.
