So far, I really like PDFfiller and have used it to edit several documents that I needed to revised for others but previously could only leave comments for users. Using PDFfiller has made me so much more productive.

I have been having trouble finding forms, and then getting the fill-in fields to work. While I like the end product I'm frustrated that it is not more user friendly.

Time is Money The document import feature, text alignment tools, and being able to directly type into the document has saved me a lot of time hand-writing statements. This is a good product. Thanks!

Fill in the Blanks! As per the 'Pro's' above, when edited could be then be immediately sent by mail to my counter-party sitting across a meeting room table. Crucially important for editing legal documents........... Every had a pdf file or document that you can't collect text sections,OR fill in a form, or add notations or extend a document. I did, and often, and I wanted it to look professional as possible, be online, so access from off office meetings was available, and documents changeable in an instant. One that when edited could be then be immediately sent by mail to my counter-party sitting across a meeting room table. Crucially important for editing legal documents. Then I found PDFfiller, it does that and more and I would highly recommend it, a reasonable cost for an excellent product that continues to update and improve its offering. Keep up the good work! A little bit cumbersome in remembering how to download a finished document, could be just me, but clearer tags or instructions might help

i app works well once you find the form you need. I'm having a problem creating new forms or updating existing ones with new information while saving the old ones.
