What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
It worked very well to get the 1099's printed for our wards. I am testing it with other things. Anxious to learn how to edit forms I had created when I had access to Adobe photo shop.

What do you like best?
I love that the physician can dictate the form to me and I can easily load the form and type it up for him. He is extremely busy and needs to fill these forms out on his own time. Now I can do it for him saving him the time to focus on face to face visits with his patients.
What do you dislike?
It is very new to me, so I am uncertain if there is anything at this point I don't like, as I am unfamiliar with a good portion of the program. But what I have used thus far is great!

Are you one that needs to easily sign documents and return by email? this is the software to use None I really liked how the software navigates you through the document so quickly so you don't forget to fill in any information, and it tells you if the recipient receives it. It's supposed to have just about any document you would need or want but I couldn't find any of the ones I needed. It was frustrating trying to look for a document and not be able to figure out where the list was.

Just plain user-friendly Very intuitive UX. Just easy to use that I don't even have to think about it. Normally I can see negatives with a product. Not this time however. Works great.

Subscription Help Review I needed some assistance with my subscription and Kara was wonderful at understanding my needs and offering a suitable solution!

I love not having to print forms, then fill them out and scan them. So much time, ink and paper wasted. Using PdfFiller I just upload the document, fill it out and send. Super easy.

I apparently didn't understand the subscription options either, like other reviewers. But after seeing unexpected charges on my CC statement I contacted them and they immediately reversed the charges. Efficient, professional, no problem. I think the subscription charges/contracts could be clearer, but on the other hand I was moving pretty fast so maybe it was my error solely. Anyway, no harm no foul. The product itself worked fine. I have no comparison so all I can say is it functions and got my job done.
