You need t tell people that if they enter numbers with commas, the IRS filing process does not work. After lots of time and trial/error, I stumbled across that as the cause of my problems.

Had similar capability on work computer(s)> I was fine with filling out PDF files and saving them. Ths allows signatures and other features that may get me to keep it.

By far, one of the best programs out there. You guys did a great job on this. I will certainly renew every year. Well worth every penny. There hasn't been one document where i was left unhappy with the outcome. Thank you again! JG Houston, TX

I like it....I didn't appreciate the automatic payment/sign up. I would have rather been notified that my trial was ending with the OPTION to renew or not renew rather than automatically being signed up.

There should not be an option for…
There should not be an option for alteration on the PDF document. For example, when I tried to type my name, I made a mistake and I back space the mistake but I ended up deleting the line on the original PDF document. A program like this should not give me the option to do that. Other than that, I felt like PDF Filer got the job done for me.

Fill in the Blanks!
As per the 'Pro's' above, when edited could be then be immediately sent by mail to my counter-party sitting across a meeting room table. Crucially important for editing legal documents...........
Every had a pdf file or document that you can't collect text sections,OR fill in a form, or add notations or extend a document. I did, and often, and I wanted it to look professional as possible, be online, so access from off office meetings was available, and documents changeable in an instant. One that when edited could be then be immediately sent by mail to my counter-party sitting across a meeting room table. Crucially important for editing legal documents. Then I found PDFfiller, it does that and more and I would highly recommend it, a reasonable cost for an excellent product that continues to update and improve its offering. Keep up the good work!
A little bit cumbersome in remembering how to download a finished document, could be just me, but clearer tags or instructions might help

Payment issue dealt with swiftly
After both my cards being declined to register my subscription, I went onto the online support chat. Kara was super helpful and quick to deal with my issue - very professional and friendly. Kara was very generous in giving me three free days and advised within that time to try my payment again after 24 hours. Thank you Kara for taking the stress away and resolving my issue fast. Morven
