I'm pretty basic- online calendar with duplicate due dates written on paper calendar and Excel for tracking work out and income in. I also have a contact database for clients that includes info on projects, the writing styles each client usually likes, the websites they own, stuff like that. I've been considering switching to Quickbooks, but I want to do some more info. I love ACT! and may buy that for myself.
I use basecamphq.com for projects, it's free and it's enough for project management. Thanks to this thread I've discovered Vista's calendar, which rocks!
Why not use the old fashioned way. Ledgers, folders, and a few organizational FREE bookkeeping skills? Your wife will help you figure it out
