Amazing value! I just purchased a subscription to PDFFiller due to being unhappy with a recent upgrade to Adobe's Document Cloud, and I'm absolutely thrilled with it so far, although I have been having some minor challenges. I suspect this is just part of the learning curve, but twice I contacted the online chat support and I am happy to say I was working with actual humans who were clearly native English speakers - a huge time saver when there isn't a language barrier! The challenges pertain to sharing documents. I was not signed up for the E-Sign upgrade, and shouldn't need to be in order to obtain client signatures, as far as I can tell. However, I don't mind signing up for E-Sign, and because the price is very reasonable, I went ahead and upgraded. I'm not certain what level of security is necessary for my line of work, and there are numerous choices available. Also, I had a problem when asking for phone number authentication, something that apparently can't be used when a document is emailed vs. sending a link. I'm still learning, but this is easily the most user-friendly .pdf system that allows for client signatures AND .pdf creations and edits, all while retaining security measures. The ease of editing .pdf files and forms. Challenges with sending files for signature and security options.
