You know, I see no mention of Quick Books Simple Start. I 'discovered' this software at the end of last year. I started using it for my 2008 fiscal year and I just LOVE it.
It's (dare I say it) a dumbed down (I hate using that phrase, but you get my drift) version of the full blown program, but it has everything a VA needs to keep their books in order in my humble opinion. It's a FREE download too. Can't beat that! Cheers!
