Excellent!!! If this doesn't help you in today's busy office nothing will. I compare it to driving downtown. You know where you want to go but can't because of all the 1-way streets. It opens up all the roads.

I have extremely low expectations for… I have extremely low expectations for customer service but I was surprised about how fast and helpful pdf filler was. My issue was resolved within minutes!

It got the immediate job done but there were a few hiccups. I don't particularly like their way text is displayed in the larger fill-in fields. The form I was filling out was very complicated and required numerous references to a "Remarks" section at the end of the form because there was insufficient space with the numbered questions to put complete answers without overwriting onto the next numbered question. Consequently, the Remarks section was filled necessitating a separate attachment to contain all the remarks. In the remarks section, I cross-referenced to the numbered question for clarity, e.g. "Question 12(b)..." When I viewed the form on the screen the formatting looked fine but when it printed, the "Q" in the word Question was on one line and everything else "question 12(b) was on the next line. I would like to know how to avoid that issue in the future.

Mostly good; however, movement from one field to the next was very slow. Also, text was not aligned properly when entered; however, it did print properly.

Great Customer Service I signed up for the free trial and ended up not needing to utilize their services. I had thought I had cancelled it, but for some reason it never went through, so I ended up getting charged for the full year. I contacted their live chat and a representative named Anna was very helpful and got the refund processed right away. Thank you for being gracious and so helpful! I very much appreciate this company's customer service. I will definitely use them in the future! :)
