I needed some legal forms quickly in a divorce case. The forms were exactly what I wanted and needed. PDFiller allowed me to do it quickly and easily. The option to color filled in text would be great.
I had issues at first as connections failed and I lost my documents that I had updated which took me a long time to do. I have had another go and it has worked a lot better.

That i was able to fix and remove unwanted documents to send just what i needed. The fact that I can fax without having a big machine to do, matter of fact that is one of the reasons that I decided to use pdfFiller. You make filling out important documents easy and able to sign by uploading just a picture of the signature needed. However you could make it easier to be able to create a fax sheet more personal. The one on the website is okay but not personal enough. Maybe I will think about doing the annual thing let's just see what more I can learn to do with your program. thank you for making it so easy to send important documents from the comfort of my home office without having to pay someone else to fax for me

I always enjoy how I can find any document I need and the site is uber easy to navigate and that is the plus, plus!
Good overall experience
pdfFiller does have a robust feature set for all document needs and the user interface was pleasant to use and mostly intuitive.
I believe that a market for single users is far less likely since a normal user would not require most of the features that pdfFiller has to offer and they would probably not use the paid version.
I would give 5-stars but you have to sign up in order to download your PDFS/Docs, i would recommend that you allow at least 2 Docs to be edited and downloaded before requiring sign-up.
