Grisbi is an accounting application with a lot of features and is running under GNU/Linux and Windows . Grisbi manages multiple accounts, currencies and users. It manages third party, expenditure and receipt categories, as well as budgetary lines, financial years, and other information that make it quite adapted for associations (except those that require double entry accounting).
