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.
Nicola C
Great product. Good interface gives you all the options you need in one place. Clear and easy to understand. The only downside is remembering its a browser only interface, remembering the product name and having to navigate to the URL to begin. Not an issue for a daily user, but if you use only intermittently like I do, I have to make myself a reminder. To that end, I think its a little expensive for a casual user; but I do still like the interface so much that it overrides my concern on cost.
Steve C
It was helpful, but it only put the payers name on copy A, the other copies had all the information there, except the payers name, address, city,state, zip.......the main header.

Nothing Particular other than finding out the particular IRS forms I expected to print from the IRS wasn't acceptable to download and print, and I had to purchase them when you advertise free IRS forms.
