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.

I like it but wish there was an edit instead of erase and text to change something. There may be but I'm not aware of it so a webinar would be very helpful.

I use PDFfiller on an iMac which does not have Flash installed. The main problem I have is that some of the text I deleted in a PDF file using PDFfiller appears to remain in the file. After I save the file, exit PDFfiller, and reopen the file with PDFFiller, the text I deleted was actually deleted and no longer in the file. So these steps serve as my workaround to this bug in PDFFiller on computers without Flash. I greatly appreciate the PDFfiller Help Team explains the reasons why the bug remains in the current version of PDFfiller, transitting from requiring Flash to not requiring it. Furthermore, as a software engineer myself, I fully accept the reasons for this bug to remain in the current, transitional version of PDFFiller. Thank you very much, the PDFfiller team. Wan Chan

So far it is working very well, i needed something straight forward that would allow me to fill in forms. I'm hoping to automate some of this in the future but right now it is I am just doing one here and there.
