An easy to use program, great features, that allows you to complete and edit PDF forms. I'm no computer expert, but found this program straight forward to follow. Makes completing forms online so much easier than printing onto paper and filling out the long way. Would highly recommend it.

What do you like best?
PDFfiller is easy to use and has widely varied functionality. From the editing of documents to the administrative/management aspects of the program, it is quick and simple
What do you dislike?
Some elements of the interface gets a bit busy. It ends up leaving me with a somewhat small visual operating space. It is worth mentioning, though, that this has improved a bit in the last six months or so.
What problems are you solving with the product? What benefits have you realized?
I'm using the templates to edit and send out letters, which I like. I'm also sometimes using the direct email function.

PDFs made easy
Since using PDFfiller, I haven't seen any PDF I can't tackle
This software allows me to edit any PDF unlike Acrobat Reader. Has other useful functionalities such as sending PDF's to clients for e-signature, merging/extracting/compressing pages as well.
I do not think this software needs any improvements. It helps ease my workload immensely each week.

Tons of great features to streamline and especially for working with client signatures. Just discovered the document password protection, which is *******. Customer service is very efficient thru the chat.
