I just recently started looking at Opencart for an open source ecommerce platform. It has a nice clean MVC codebase, and has support for multiple stores. Having multiple stores offers a great benefit of creating different marketing opportunities by using different themes or product offerings. Opencart has several useful reports that are included by default. Wanting to use Opencart for multiple stores, I saw that the Sales Order report didn’t allow you to view sales by store. I put together this vQmod xml file for Opencart 184.108.40.206 that adds a drop down filter for store names.
