Excellent Experience! Only suggestion is that PDFiller should offer free services to individuals and that will prompt businesses to buy your subscription just like many other online tools are offering, for example, FreeConference, GoToMeeting etc.

It's very good the only thing about it is you can't copy and paste because the words will go off the documents also the little box you can type in be off so it makes the documents look odd

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

An excellent program, my only gripe was/is after paying for this program, I began to experience unsolicited X-rated and non-X rated ads. And, interference using Safari on an Apple PC

Good so far; expensive, however, AND when I agreed to your discounted one year offer when I intended to cancel after one month, I didn't realize the sum offered was in addition to the $20 one month fee, so it didn't turn out to be such a great deal after all. I was canceling, because I honestly don't see myself using this much more if even ever again. However, for the discounted rate (WITHOUT the $20 added in), I thought 'why not?' I am going to evaluate over the next couple weeks to see if I really DO want to continue a subscription, discount or otherwise.

PDFfiller is both handy and speedy, having it at my desktop saves so much time. I never had any training so any problems with it would be entirely my own fault: seems a little clogged when done with the project.
