What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It meets my needs very well. If I could get my own fax number for less than $10/month I would add that. As it is now, I have a fax separate from this but only pay $8/month so will keep and use separately. Disappointed it was so much for the add on. Also, for the edit option. Many things to do but all as add ons. For now, I like what I can do, though.

It's easy and I use it for billing for my private practice. There was a recent change in the function of the program that you have that has caused me extra time. I used to be able to look up my form by name using the little magnifying glass and then when I found it, click on the form, and then click on the copy icon. The copy icon isn't present anymore when I look up the form by name, so I instead have to scroll back through all of my forms and it takes a lot longer. If I could still look up by name and then copy the form once I found it that way it would be great. I used to be able to do that until the recent formatting changes.

It was interesting using the PDFfiller on two different computers. On one I couldn't get the scroll down bar easily, whereas on the other it was simple. Don't know why. I also noticed that there were different options to determine exactly where on a line you could type, however, it was difficult to gauge. FYI: I just started using this application.

I write reports for evaluations. Litigation has mandated that these reports be quite extensive. Handwriting them took hours. Scanning the forms into a pdf and allowing me to edit them is immeasurably helpful to maintaining my sanity.

So far it is good. I use it for work schedules. Im very busy so havent had a lot of time to explore all the features. When i send my work from home to the work place; i find the security code a little annoying. Also when i purchased it i didnt receive a lower price as lead to believe. Although the price to continue useing it at renewal time wasnt bad.
