I love it, it's more user friendly and reasonable than Adobe filler and keeps changes, doesn't always work that way with Adobe. The only thing is it needs alignment buttons, like center, left or right justified. Setting up new forms requires much counting spaces to center. Other than that am happy thus far with the program.

Found it difficult to navigate through at first but after using it a few times I figured out what I needed to get done but I'm sure there are easier ways to do things in there....

Outstanding Online Support I have used Pdffiller for the past 4 years to file tax returns for an investment group with over 40 members. I made an error when creating my template and when I went to print the 40 documents an erroneous number was appearing, the result of my error in creating the document. Fortunately Pdffiller has an online support staff. So many online companies require you to submit a ticket and then promise a 24 to 48 hour response time. Pdffiller offers that option but they have an outstanding online chat support. I had the benefit of working with Ryan and got access to him immediately upon opening up the online chat support. This was in the evening but Ryan thoroughly researched and tested my issue. Sadly the only option that appeared to be the answer was to create a new set of 40 documents which Ryan was willing to teach me how to create the docs in way that would avoid this error. When I expressed my issue with not having another 6 hours to re-create my work, Ryan persisted in finding a work around that was very creative and saved me from over six hours of new work!!! Needless to say I was ecstatic!!! Thank you Pdffiller for not only a great product but an online support staff that truly cares about helping customers get the results they require!!

Subscription and refund I Had £91 taken out my account for a subscription that i didnt know i had and could not afford, I went on the live chat and spoke with Maria, i told her my issues, she went above and beyond to help me. She managed to cancel my subscription and issued a full refund she was an amazing agent

No Scanning! I'm just PDF Filling It makes capturing my customer's signature hassle-free as my business is online. No do-overs! Thank you! Because I make it mandatory for them to sign after placing an order. If they decide to change the order, within the specified time, they can sign to that too. What I like least about this software is that when actually filling in the blanks, the words do not align with the original text. This is an area that needs improvement.

Great service and software Great service and software. I used PDF filler to edit and sign a couple of PDFs and the tool is easy to use. I've also made use of their customer service and they responded fast and adequately! Great tool, great service! Thanks for being awesome!
