I wish the opt for yearly subscription would let you pay the mo rate instead of the full balance. I'd love to keep this service but couldn't afford the yr fee only the monthly19.99

Wish that the tools were better on the app. Very limited there.
Also that there was a square/box that could be drawn, not just the addition of a circle.

Thank you for this program! It's so much easier than another I have tried and I have more to learn about usage when I have more time. Just trying to get something fleshed out relatively soon for now.

I am able to find everything that I need with running my Bookkeeping Tax Prep business from T4's to GST remittance. The price is a great price as I am a small business, it is affordable to small businesses. I am glad that I found this and look forward to using it for a long time.

What do you like best?
The ease of filling in forms and quickly.
What do you dislike?
Nothing except that when I print a doc, the Print button is at the bottom of window and I can't move it up so I have to click the very tip of the box that says print. - This could be my computer problem too but is weird and that just started about 6 months ago.

Good less expensive alternative to some of the competition
Overall, I have been satisfied with PDFfiller
The software works just like advertised. I love that it is super reliable to work when I need it.
The user interface was slightly challenging to get used to but after that, it has been nice.
