When I first signed up, I only wanted a personal account. They system did not provide me with an option to choose, that I could see, between accounts. It automatically signed me up for professional and now I have to jump through a few hoops to cancel the pro and sign up for personal.

great except when i want to email something sometimes the other party can't view it as a pdf. i dont get why. I want an option to save my new document in my own hard drive but can't figure out how to other than emailing it to myself. add that option or help me find it.

Filling out form was fine. I felt like I should have been told there was a cost associated with use before I filled out form, not when I finished. At that point I didn't feel like handwriting everything, so I paid for subscription. I can't justify spending $72.00 a year for something I will seldom use. Wish I would have known up front this was not free.

It was easy enough to use the first time I tried. I was able to fill out my 1099's within a couple hours and file them with the IRS. It was so simple! I appreciate your service.

For the most part, it is a helpful tool. However, I will need to cancel my initial free subscription because one of the documents I would be using on a bi-weekly basis would be for payroll purposes. Unfortunately, when I scanned the document, I was not able to enter numbers in the fields. After several attempts, I checked the hardcopy document and it has a feature, which requires an applicant to fill in the document with a blue pen, something I was not aware of ahead of time. Evidently, the company had the documented protected to only read "handwritten", blue pen entries. I would be using the document as mentioned above for other candidates on a weekly basis and since this product, through no fault of its own, won't allow me to do that, it doesn't serve my business purposes.

Great product...relatively easy to use Great product...relatively easy to use, especially if one is familiar with this type of document editing app. I am please with how much of a time-saver it is. I couldn't give 5-stars because the cost of the "Full Version" is really too expensive for me, but other than that, it's a very handy tool.
