This is only my second time but I do like how easy it is to type directly on the file. Just waiting to make sure they received it on the other end. Thanks

So easy to use not being rejected
My bank required my signature not an electronic signature. Maybe if I used my signature on pdf format I will try that next time.

Just what I was looking for. Liked the smart software that figured out what fill-ins of IRS forms were in teh wrong spatial location in a box and which ones needed to be copied to later pages.

PDFfiller is great if you need to edit/change PDFs
This software allows us to fill out and share PDFs, vastly cutting down on our printing/scanning song and dance.
No real negatives other than I wish it were free.

PDF Filler has been a great tool for our business for a professional look with a great price.
Professional Look for a cheap price. The software makes filling out government documents / applications and other PDF documents easy and efficient.
PDF Filler provides and saves time when filling out applications / tax papers / and other business files. It creates a professional look and is quite easy to use. With common files also at hand it makes filling these out quick and easy. The mail tool was even used when we completed our taxes. PDF Filler printed the paper out and mailed it themselves without us ever having to go to the post office.
There isn't too much. If I could say anything sometimes the website moves a little bit slower than some. However this seems to have been improving lately.

Searching for a form that I had…
Searching for a form that I had difficulty finding elsewhere, I found it here upon oa couple tries. Having trouble with the editing, which I always do. This site is superb, I'm just a tech dummie with a capital "D". Gotta go or I'd say more. Thank you for your excellent product and great free trials.

Having to make the check boxes into…
Having to make the check boxes into check marks instead of x takes while when you have twenty on the page. It would be nice if you could decide for the whole page.
