Too many systems try to be all things to all people. We'd rather do one thing and do it well; and for us, that thing is ecommerce. FoxyCart is not a CMS. It's not a mailing list manager. It's not CRM or inventory management or affiliate tracking. There are plenty of great applications that do those things excellently. We'd rather put our energy into being the absolute best ecommerce platform there is, and make it easy for you to integrate with whatever other systems you already know and love.
