overall I like pdffiller, but there are some things I wish I could do, like circle items in word docs. The only circle function I see does not seem to work very well. I would like to be able to draw circles around items more easily. As for signature authentication, is it necessary to include date? It would be easier if the authentication did not include the date. This isn't a big deal, since I can see why the date is necessary... but sometimes I sign a contract on for example, Sept 1st at midnight, but I don't want my clients to know I signed at midnight Sept 1st, particularly if I should have signed the document sooner. Anyway, these are just little issues that I've come across and changes would make my business a bit easier.

PDF Filler Review From forms, to contracts and or agreements I constantly have to fill out documents and then sign them. Your software facilitates these for me in addition to protecting them in a pdf format. I enjoy using your software portal and it solves 99% of my problems. The only issue that comes up from time to time is that when certain large vendors send me a form to fill out and I return it to them they do not recognize it. They want me to use Adobe instead, which I do not care for. I wish there was a way to save the finished document as if it were compatible with Adobe.

I am not the most skilled with modern technology. As a startup NFP we don’t have the financial capacity to either hire, or contract with an accounting professional to prepare our year end 990s. I personally took it upon myself to do the necessary paperwork. I kept losing my work, and did not know how to save it without Word. I stumbled upon pdfFiller and decided to sign up. The retrieval and storage of my docs (either completed or still being worked on) is so simple now that even I can do it! The work has become easier thanks to pdfFiller. Thank you. Matt

PDFfiller I am happy with the software and it helps me to speed up my paperwork and save my time. What I like most about PDFfiller is that it is very easy to fill out the form electronically. It fills out any blank space of the PDF form from the loaded document. No negative review on this software. The software is so easy and simple to use and I use it at work when I need it.
