very difficult to use -and the system does not total the # on each page like turbo tax does -not user friendly -hard to go back to add forms -that you did not originally prepare

PDFfiller seems to do everything I need, thanks. The only negative, and it's hard to pin down, is that the UI (user interface) seems to be overly busy and cluttered. But it works.

I was a bit unsure about whether non alphabet/numbers should be added. I was also unable to add my initial after my surname (just typing it) as the filler kept on opening the initial (as in signature) block.

Mam rada jednoduché a přehledné aplikace nad kterými nemusím zbytečně přemýšlet, neboť to většinou vede k tomu, ze úplně ztratím hlavu a prvotní myšlenku, ktera mě tam zavedla. . Takže v jednoduchosti je krása.

A feature that is critical to my business broke on Friday. I was able to interface and get updates about the fix over the entire weekend and had the problem solved by the dev team before Monday morning. Awesome teamwork from the folks at PDFiller from end to end. Highly recommend.
