What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Initially, it was a bit confusing. However, after using the program a few times, I am delighted. I very much like the fact that I can take a printed form, scan it, and then fill it in and print it. The result is very professional looking. Still not sure how to change fonts.

I like that I can erase parts and add text of size and font that I like and move it around so it's where I want it. When I erase part it doesn't cause the rest of the document to move around. It stays put. That is essential when I am editing a document with a puzzle at the bottom.

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!

Easy to use
I couldn't find what I was looking for on the CRA site and this popped up in my search. I have used it before for Real Estate forms. I didn't know I could use it for CRA forms too.
I love how easy it is to use.

Good thing!
Very suitable thing for paperless work with documents. I can do that everything from my tablet and there is no any need in rewriting docs many times!

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.

I've had a good experience with pdfFiller but I'm still having difficulty navigating what exactly or how exactly to get blank forms that would help me in my current job, which is office manager for a plumbing company.
