Although I found it quite confusing I eventually understood it better. The Customer care that I was able to contact using the system was very helpful.

It's pretty good, but some repeat items don't load, and a couple times it would not let me add a 3rd line in a box. It would be nice if columns of numbers could add up.

Adobe should take notes from PDFFILLER I like that it's web based which allows me to use it on any computer without having special software installed. Nothing too bad but sometimes the converter feature would hang when I was converting large documents.

Can be a simple way to fill out documents. I can fill out a document pretty fast. Its functions are easy to understand. Overall it is easy and anyone can use it even if they are not tech savvy. I don't like how I can't control the fonts and the font size. It automatically selects the font size and sometimes it can not be changed.

pdFiller worked great for filling out… pdFiller worked great for filling out immigration forms that wouldn't let me fill in blank spaces that my regular pdf editor wouln't let me.

What do you like best? I love the fact that we can collect uploads AND money through filled PDFS What do you dislike? The entire site is very confusing and we have a hard time understanding where our active sheets are located within the site. We see things like "documents" and then we make a new template ... then lose which template is live and which one isn't. I also don't care for the fact that we cannot choose to have ZERO color in the field that the customer sees for filling in and I would love to be able to disable the "lock to grid" feature that is clearly on at all times. Recommendations to others considering the product: I recommend reading through the site, reading through all the tutorials you can and getting very organized about what you are going to do before getting started. What problems are you solving with the product? What benefits have you realized? We no longer have to deal with faxing our documents to customers to fill out, sign and fax back. We just tell them to go to our website . They are also so much more likely to complete the entire process including sending us pictures that we require and we no longer lose the pictures or get confused as to where everything is.
