I'd really like to suggest my recently opened-source ERP project Stockor, but it's not quite there yet accounting wise. While it does have a full double-entry accounting system inside it, it's not fully exposed to the user right now. It currently does purchase orders, invoicing, and writing checks just fine. It's just a bit opaque on creating ad-hoc GL postings and modifying the balance statement. If you're not in a huge hurry, check out stockor.org in 3-6 months :) Contact me if you have further questions or would like to beta test some stuff.
