I have been using MS Money Business. It is cheap enough for a one man operation without any bells and whistles. I would recommend Quicken Business because you can update to QuickBooks in the future if you need too. I tried a software package called "Bookkeeping" which I bought from Staples, it is only for someone who doesn't use any credit cards, so I would say don't bother with it. I returned mine to the mfg and got a refund.
