This program is excellent, there is a form for just about anything you need! The features included are awesome how you fan sign, fax, email, etc. I love how you are notified when your document is viewed, and how records are kept!

Works well, but not sure why you create a page that cannot be scanned and sent to the IRS on the first part of the form. If this is not legal or usable why have it?

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.

I am brand new to the software. I know some things it can do because I have friends that use it. However, I would love to know more about what all I can do with it.

Easily Add and Delete Pages From PDFs PDFfiller has saved me a lot of time combining PDFs and adding/deleting pages. Definitely a must have software. I like that I can easily add and delete pages from PDFs. They also make it super easy to combine PDFs together. Overall, very happy with the platform. Might be nice if there was an option to upload and download to Google Drive.
