I have been using PDFfiller for years introducing the product to companies that I have been employed and in my personal life. I think it is a great product for producing documents, faxing, email, changing forms with ease or having documents signed in a quick and efficient manner. Thank you PDFfiller, you have made my work life a lot easier.

A good all rounder for filling pdfs and signing forms
pdfFiller is a useful tool that lets me fill, sign and send client contracts
I like being able to add text to pdf forms, then email,download or print the completed forms
I have to be honest, it's a bit clunky and takes some getting used to

I am still trying to figure out how this program works. I am doing the basic task. I know there are other things I can do I just don't know yet what I don't know. LOL

A perfect user-friendly PDF Editor
`*I usually don't look forward to doing PDF editing as it is usually a nightmare. Nothing lines up, missing a feature you need, doesn't save correctly, or you can't send it, etc.
This is the first PDF editor that I actually have fun with, super user-friendly, fast learning curve, yet looks professional, is feature rich [in fact it has features the others don't have], and no problems saving and sending or later editing it again down the road. I am just ending a one month free trial offer and will gladly renew it as my permanent PDF editor.

The only problems I have is my limited use of the software. It works great for someone like me who just started a business and need invoice templates, proposal templates and estimate templates

Just a few suggestions
I have used some other comparable products, but pdfFiller offers the online hosting that makes it super convenient for the user to fill out the form without having to download the form first. However, I have a couple of suggestions. I wish the pdfFiller could have the feature to automatically convert the raw entry data (e.g. phone number 1234567890) into the selected format (e.g. (123) 456-7890), instead of asking the user to enter it into the specific format. I also noticed the accident that some fields will be deleted accidentally when saving the edited version in LinkToFill. It happened several times to me when I was editing my file. Not sure if that's an internal bug or an accident from the internet interruption.

I really like the capability of downloading forms, completing them and signing to send off.
I wish I did not have to log in each time. That would be a great plus as I work for several clients and need the quick ability to do a form and send to them.
Thank you Alice

The experience is great because there have been some documents that I needed to change, but for the free trial I wasn't expected to get charged at all. It's free for a reason. That's all apart from that, it's a great tool to have.
