Application is predictable and user… Application is predictable and user friendly, easy to handle. Most forms available within the website or easily finds them. Now when I need a form or fill one of mine documents I know is a done deal. Highly recommend PDFfiller.

PDFfiller in a medical office Overall, very pleased with the program. Love the east of use, wish the file saving was a little easier. I like being able to upload patient forms that need completed (i.e. FMLA or short term disability) and completing neatly with PDFfiller, instead of handwriting, etc. I love the east of emailing or faxing directly from the program as well. The confirmation of receipt or email being read is nice. Some times the text boxes are difficult to line up or get placed properly but I really feel with more use I will become better with these small tweaks.
