Check with your accountant. Some are uncomfortable with Quickbooks, which doesn't really close off year ends, i.e. you can freely enter things into ancient fiscal periods, which is a bit weird once year end should be closed. I know some folks who swear by Simply Accounting, which I've never used but friends say it's great for people who understand bookeeping principles but slower to learn for those who don't. It closes off year ends, has flexible reporting. So I'm told.

Software selection is a challenging thing to do--it takes a lot of work to fully understand your options, but time well spent, very well spent.
