Seemless interaction so far, good online support.
The company does not yet have the CA Residential Purchase Agreement and Escrow Instructions (effective 11/26/14) available, my only knock. May not be released yet to public as a non-draft document. Ralph 12/13/14

There have been a few times I have been frustrated because I can't access my documents. Get an error message but other than those 2 times I am extremely satisfied with it

At first I did have problems figuring out how to use it. I don't see a "copy/paste" button and wish there was one. Overall, as I start to use it more and more I am liking it.
Regards.

Well, I just got it and I am exploring its features... Too early for me to give a feedback. I'll be able to tell you more in a couple of weeks, I guess! Thanks!

Great application for getting forms filled out quickly and efficiently. Love the feature of being able to mail directly from the application and have used that several times.

What do you like best?
PDFfiller actually has lots of online tools that can help with many general document editing tasks. We can convert PDF files to lot of different document formats such as DOC files, which are files I use often at work. For document signing, editing and adding fillable fields is not complicated. The toolbar has tools that are neatly laid out and easy to access. There are lots of click-and-drag features that make using PDFfiller comfortable, even with hours of editing. There are also helpful collaboration options that let internal staff communicate about document edits.
What do you dislike?
From an admin perspective, it's been a delight working with PDFfiller, but some people that receive our digital documents can sometimes have trouble accessing the files and knowing how to sign them.
Recommendations to others considering the product:
PDFfiller can be a valuable solution if you need to make lots of edits to PDF files and don't have a much experience with more advanced software like Adobe Acrobat. It seems to be designed for beginner users, but can also work for more expert document editors.
What problems are you solving with the product? What benefits have you realized?
Even though I know how to use various popular PDF and document editing software, I often turn to PDFfiller to allow for more intuitive editing features and its abilities to work with just about any PDF we load into it. It's a versatile editing solution that lets us quickly format our documents to our specifications.
