Leonardo brings up a good point ... it depends on what you are trying to do / build.
If you want a pre-made solution with a lot of e-commerce specific bells and whistles, you should definitely check out the e-commerce application frameworks that are out there.
Remember that Qcodo is a development framework, so it doesn't pre-define any application-level objects. What Qcodo gives you is the ability to quickly build modular, efficient and maintainable applications, regardless of whether it's an e-commerce website, intranet portal, content management system, etc.
Best of luck!
