BeansBooks

BeansBooks is a simple cloud-based or local accounting from System76 in Denver. It is open code; the software can be downloaded, installed, and modified for free. However, the cloud-based version can be had for $29.95 per month. For this, the user gets unlimited transactions, users, vendors, and whatever else with all the rudimentary accounting features omnipresent across accounting platforms (a profit and loss balance sheet, GL, basic AP / AR, purchase ordering, expense management and invoicing). It is extendable with addons and has a developer API. As it is open source one can try it for free simply by downloading it, and pay for the cloud service later if desired.
