I am really happy with pdfFiller and excellent support staff. Really thankful to them for prompt response to my queries and sorting them out quickly

Initially
Initially, it was a bit difficult to insert the text; but after a while I discovered the "T" tool for aligning texts. I also like the fact that I had choices for signatures.

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.

Great application for anyone that constantly has to have documents filled and e-signed! Would recommend it for anyone in an HR or customer service role in a business.

Support team is on point.
I was charged for a one year subscription even though I had cancelled before the 30 day free trial was over. The support team immediately resolved my issue. Within a couple of minutes. Special thanks to John.

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed.
I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature.
I use this all the time in my business and I would recommend it.
