After initially getting the hang of it, this was the best fillable system I have ever used. Customer service was outstanding and I will definitely continue to use your service. Thanks again for making this such an easy process.
PDFfiller tools equip me with ability to provide documents from my home office instead of going into the office to use printers and scanners to complete documents and send.
Its been great. I had an important application to complete and because of this software, I was successfully in completing it and looking professional at the same tim.

after years of hunting I finally found a pdf editor that is powerful, easy to use and reasonably priced.
Our previous subscription was deactivated because no one seem to know the login or password for the account. It was assumed a temp employee had subscribed who is no longer employed. Difficulty accessing and filling online forms prompted us to re-subscribe. This morning's experience has been great and we plan to continue using this application.
It is not very difficult to navigate, but I do have issues with finding some of the documents I need. Plus, I feel that the pricing of basic level is too much. I am a person with a limited income and can not afford much. I need this program to help with my taxes and a few other documents, but I can not afford to pay an entire years worth!
Thank you so much for the super prompt reply!
I had somehow removed the date stamp from my digital signature and I could not figure out how to get it back on. Turns out it was a pretty simple fix (doh!). Kara responded super fast to my cry for help. She provided written instructions as well as a screenshot (very helpful!). My date stamp is back on. :)

Took me a while to figure out how to delete an entire page. My one suggestion would be to leave the previously used tool activated. I get tired of having to click on "eraser" when I'm trying to erase multiple blotches on a scanned article.
