Today I published a new extension for the OpenCart open source shop. This extension enhances the sales report in the OpenCart administration. It adds a new column presenting the sub total of the orders. The sub totals represent the prices without taxes, discounts, shipping costs, etc.
The extension can be found at http://www.opencart.com/index.php?route=extension/extension/info&extension_id=2503
