I use the online version of QuickBooks Simple Start Edition. Good enough for a small host like myself, but also good enough to make sure I have everything together tax-time since I am a registered business.
Biz Hosting Networks choose Peachtree. It is more difficult to use; however, after you learn it, it is great! Between the two software programs I would have to go with Quick books. I was trained in Quick Books and I find it very easy to use and money I have my doubts about.
