The best service ever! As a chiropractor, I am able to fill out my exam and soap notes with pdffiller then save them in the encrypted files for Hipaa compliance. My office is on its way to paperless as we speak. I love this service. Highly recommend it to all.

I needed to fill out a one-off 6 page form and was looking for a free app to do it. When I Googled for this you came up and I did not track it was not free until I completed the form. Then I was "stuck" b/c I needed it asap and the request for payment did not come up until the end. I was not happy and would never have used the program had I tracked what happened. That being said, it was an excellent program and if I had to fill out forms routinely, I would recommend it. But since I don't need this app, please cancel my subscription.

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.

Great Customer Service Great app, but even better customer service. I needed to cancel my membership for financial reasons, but I failed to do so before it renewed and my bank account was drafted. I submitted a request through the website for support and requested a refund. Zoe replied via email within an hour and had already issued the refund. Clearly they care about their customers, provide easy communication options and have fair policies in place.
