While I understand that you want to get subscriptions for a whole year and renew those subscriptions annually, I would prefer to have an invoice at the end of the year, so that I could decide if I wanted to continue using your service or not. I really resent automatice renewals. Hence I went with the month to month as my need for your program may only be for a short time.
T. Elfers
overall it is fairly easy to use and it is clear, but it is not straight forward if you want to continue on with the next form, ie when finishing one form 1099 and you wish to do anothe

What problems are you solving with the product? What benefits have you realized?
I am able to neatly complete forms and send them electronically. Much better than filling in by hand.

JUST AS GOOD OR BETTER THAN ADOBE PDF AND CHEAPER Used for filling out electronic documents, easier than filling out documents manually and then having to scan them in order to email them. Easier to use than adobe PDF, at a better price. No complaints about this software as the time of me reviewing it, so far very content with it.
