So far it works great! There's a bit of a learning curve, but I was able to chat with a support rep even though it was late at night. He helped explain how I could achieve my goals for our Robotics team engineering notebook forms.

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.

Easy to use for 1099 filings Use for 1099s and other tax filings. Used this product for 1099 filings.. simple and easy to use except for ability to make edits (address changes etc.) once filed. Once a 1099 is filed, program does not make it easy to go back and edit a document. Also, any updated filings are charged another filing fee, which seems excessive.

Easy to use with all the features we need for a pdf The way you allow to edit document is really great. Adding pages and adding images to pages works really well. Finally some application that has almost all the features we need to create or edit pdf.

Interesting product the pdfFiller. I would like to learn what else I can do with this software. The new look for the PDF is wonderful but I don't know if I would be able to use the old PDF from Microsoft. It seems I just paid my Microsoft subscription. It seems that the PDF is a software of it's own and doesn't come with the Microsoft Tools.

Best In pdf LOVE it! Everything thing in this app is easily navigated, you are able to save documents to revise later. A big pro for me is when you send a PDF, say as soon as you hit send, you are like "oh my goodness I forget a important part" You can go into that sent email and revise or add on. As long as the recipient has not opened it yet. Im not fond of the code to open the PDF you have sent, expires for them. I'm still rather new to this so I plan on leaving another review once I figure out ALL the kinks of the app

Great customer service I didn't use the service, and my payment was refunded so easily! Most companies are not as willing to offer that level of customer service.

There are some minor things I have not figured out... There are some minor things I have not figured out how to do. Not sure yet if they are just missing features, or just not readily available in a way that I was expecting.
