Zoey is built on top of Magento (a hosted ecommerce solution) but is sold as software as a service (SAAS), so you don't need to touch any code to get the most out of it. Zoey combines Magento's flexibility with Shopify's user-friendliness and is the go-to solution if you run a wholesale business. It's mainly aimed at B2B stores and as such it's pricing can be a bit discouraging for startups, starting at $299 per month.
Aside from the high-end ecommerce features, Zoey really shines in the design department, with some great templates and lots of ways to tweak them just the way you want.
