The Expense Submittal System (ESS) is a Web-based 'soup to nuts' solution for expense report processing. ESS provides report entry, approval routing, corporate policy checking, credit card statement importation, report payment, and G/L feeds. ESS is highly configurable. Standard feeds include ACH file creation and current SQL supports MySQL, Oracle and ODBC databases. ESS is licensed under the GNU Public License as open source. It has all the bells and whistles found in "closed" corporate expense reporting applications or outsourced solutions at a fraction of the cost.
