I haven't had a chance to play with it yet, but considering how lax I am with paperwork, I think I'll give it a shot. I'll report back once I've had a play with it.
The Freelance Switch blog had a review of Cashboard here.
I also noticed Cashboard offers a free downloadable time tracker widget from their website, cute!
