I would like to be able to make sub-folder with in sub-folders. I am going to have hundreds of documents/year, and that would make it easier to organize them.

I have been very happy with the functionality thus far. I may be interested in a webinar in the future. A survey in a month or two would allow me a better sample to assess how PDFfiller will work to meet my needs.

I have only just started using PDFiller.com and I am very happy with the product. My only compliant is that I was forced to subscribe to it without the option of a free trail etc When I did a search on the web for a free PDF Editor, PDFiller.com was one of the websites that popped up, I edited my document (which was a theory paper that I had already spent hours on !!) and when it went to saving it I could not without paying for service... so not a free PDF editor!!! And you can not subscribe month to month, you had to pay for a full year. I know that is business but very deceiving!

What do you like best?
Allows unlimited potential to edit virtually any document and send it electronically or conventionally. This software is a time saver/life saver.
What do you dislike?
The drawback. The Eraser tool. This tool could use some work as far as the shape of the tool. The option to be circular as well as the normal shape would be of great assistance when editing. A competitor of yours, sorry to mention uses an eraser too that is amazing and I have thought of switching simply for access to the editing qualities of that software. It allows for the one time purchase of their software and I would not pay monthly fees to maintain it either.
Recommendations to others considering the product:
Try out the product and use it!! See what you are missing!!
What problems are you solving with the product? What benefits have you realized?
The editor allows our office to clean up and mark up documents received in our office such as lease agreements or forms attached to a policy which either enhance or negatively impact the clients coverage from year to year. We directly not on those forms in our proposals during renewal negotiations so the client has specifically seen and reviewed how the coverage impacts their insurance needs.

tough start, but Sam saved the day!
SAM/ JULZ WAS WONDERFUL! SUCH A GREAT SUPPORT! After spending hours trying to fix the problem earlier and having no luck with the calling from billing dept. One agent hung up on me! He came to the rescue, worked to TEACH ME how to walk through the issue and solve the problem. I am so grateful! I will always ask for him in the future! perfect 10 for his effort and going out of his way to help really solve the issue and teach me how to handle it in the future!

It is a little difficult to figure out how to load an existing form with the saved name. I also had to Google how to enlarge the font. Most of the help directions are outdated, but I did finally figure it out after a lot of wasted time. I DO like the program in general and love being able to convert and save in a different format.
