This is easy to use. Since I have only one document to process and a CPA does my taxes, the cost of month-to-month seems high. I do hope it's easy to unsubscribe. I can't stand the way peoplefinders tries to undermine one-time usage. So thanks for your clarity and integrity.

I complete 1099Misc for my office annually. I just discovered your site which is handy as far as anticipated amending and last minute entries. I am having trouble with the How To's of IRS submitting and multiple entries.

The only thing I really had a problem… The only thing I really had a problem with is that I completed what I thought was a "free" form and then had to sign up for a free trial. The actual program is very useful and helpful and relatively easy to navigate through.

It allows us to insert a place for digital signature that is legally binding in the documents. Saves a lot of time and money from both sides. PDFfiller is best tool for pdf editing online. It includes plethora of functionalities for editing pdf. Some of the functionalities I like include add text, note, watermark, redact, draw, add images/videos, textbox, date, checkmark, search and replace text, spellchecker, undo and redo, copy and paste, and pdf toolbar, add branding and Document signing and many more feature. PDFfiller supports integration with major cloud platforms including Dropbox, Google Drive, One Drive and Box. One of the best and easy to use tool for filing and storing all sort of forms electronically. Allows you to convert pdf files into other formats such as Microsoft word, excel and ppt. 'Send to Sign' feature is a boon to corporates and legal industry. Some of the advanced feature require a great learning time from the end user. Sometime you would not get expected results while converting a Pdf to word in terms of change in formatting which is difficult to edit. Sometimes the tools is slow while working on large size files.

PDFiller... Where have you been all my life ? User friendly. Check! Quality of software for your buck. Check! Customer service that actual cares. Check! Seriously. Look no further. PDFiller is the best thing I have ever stumbled upon! This product is SO easy to use! I struggled with other software for my needs of filling in PDF forms. I stumbled across PDFiller one day while on a quest for software in order to do so. I looked NO further and started with a free trial. I instantly paid for the subscription no questions asked. I had found the program for me! If you have any conerns or questions the customer service is top notch and very helpful. Everything is labled for ease of use. I use PDFiller EVERYDAY! Buy the subscription .... you will thank me later. Con: I cant draw lines on surveys with ease! That is something that I wish I was able to do. There are options to draw but no straight edge lines. That is really the only con that I have.
