The tasks I needed to complete I was able to facilitate with PDFiller. I was later informed of a more economical manner. I manage a non-profit org. We always need to be conscious of cost.

What do you like best?
Easy to use but comprehensive options for editing. Quick and efficient which is important with time sensitive docs and a busy life. Some recent new features tells me the company is progressive. I was having technical difficulties one day and support was responsive. I've tried numerous PDF/Editing programs. and this is by far my favorite. It's web based not some ap that you have to download that later crashes your computer. Can access it from any PC so that helps too.
What do you dislike?
The price is substantially more that I'd like to see. Takes a bit to save file to PC once done editing. can be a little slow at times but still a reliable tool I use at least weekly if not daily. Something in the $50 range would be delightful and it's well above that currently. Maybe efax for this price I have not used the esign feature yet so maybe will try that given our member benefit program is lapsing.
What problems are you solving with the product? What benefits have you realized?
Quick way to edit and correct documents. Easy to save and access later. Lots of options for composing sending and revising. I only use basic functions but there are several ways to use this valuable tool beyond the features I use that exceed other competitors.

Works pretty awesome. I edit pdfs on the regular using this software and it's very fast and easy. It's very easy to edit pdfs. I have to edit multiple pdfs and I use this software. It's very beginner friendly and its a simple tutorial to show you exactly how to edit the files. When you edit the text it's never the same font as the original pdf so it's very noticeable. If that's not a problem to you then you'll love this software.

Easy Cancellation I don't usually need to fill a pdf but this one time I did. I was pleased that I got the free trial. I used it the one time and was able to cancel the next day. Thank you, pdfFiller!

used a handful of other pdf programs, and while there have been a decent one here or there, most have been quite irresponsible, irresponsive, and irritable! pdfFiller is by far the most user-friendly, quick, and manageable one there is, notes this observer! am definitely glad i went for the platinum membership - has not only calmed my disdain towards pdfs, but i am actually having fun with them now! ^_^ salamat poh, y arrigato, mi llamato ~

Kara was VERY helpful Kara was very helpful, especially in suggesting we do a Zoom screen share, which made some problems I was having with navigation and document publishing much clearer. She should get a raise.

We have had a service application on line for several years. People have been printing, handwriting the answers to our application and emailing it back. I just received back my first fillable application and I love it. It is legible and all the answers appear where they are supposed to no more writing up the side of the page because of the limited space for answering.
