good solid editor-- would like to see other payment choices, like a quarterly option, and even instead of relying on automatic renewal, send a reminder email prior to the renewal to ensure the user is still consistently using product

I like it but wish there was an edit instead of erase and text to change something. There may be but I'm not aware of it so a webinar would be very helpful.

It would be easy and helpful to implement: A tool which allows you to pick the colour you want (and be able to use that colour to erase, paint and write). A auto text-detector and erase

I am so thankful for its many abilities. I am glad that I can skip the conversion to Microsoft Word first before I can fill the form or edit a document. It has saved a lot of time for me.

What do you like best?

What do you dislike?
Sometimes the system will not allow me to download the forms I've edited. Sometimes there are glitches in the system that prevent us from logging in and saving documents. Sometimes system can be a bit slow, I notice it more in the afternoon where people may use the system more.

Great to mark up documents.
I like this software and they have a money back guarantee of 100 days I believe.
I use this product to mark up documents and sign. I like to keep everything that I do 100% electronic, so with products like this, I am able to do so.
I haven't found anything wrong with this software. It is great for any industry who deals with electronic PDF files.

pdfFiller Review
Easy to use and one of the best software to use to sign documents. Also great when you need to edit pdf files.
There were some issues when I tried to fill documents online. Find that I have to download the document.
