I have created a website for accounting applications with loans receivable, general ledger and cashbook; it was done in asp.net 4.0 with mysql 5.0; It can track age of loans receivable, can generate individual loans ledger, can total releases made and collections made during the month; The cashbook monitors the ins and out of the cash, at any given time you can check you cash balance; while the general ledger records your income realized from your loans as well as record your expenditures so you can track your net profitability.
