Quicken or QuickBooks works pretty well
OK, fair disclosure... I wrote both Quicken for Dummies and QuickBooks for Dummies. (But then again I also wrote books on just about every other major accounting software package, too, in my day...)
That disclosure made, here's my thought. I think you can get by with something like Quicken or Microsoft Money. Service businesses are really easy...
P.S. I'm a CPA.
