Shopify is an easy to use, scalable, and performance optimized hosted ecommerce shopping cart platform. The platform is oriented for small businesses that want to get to market quickly and keep their project and on-going costs at an affordable level. The platform itself is fairly powerful in comparison to other small business shopping carts and can be customized to create gorgeous store designs. Their app marketplace is extensive and allows for quick and relatively easy integration of new features and functionality. Shopify is a great solution for businesses doing under 1 million in revenue that don't require a high degree of integration or more advance enterprise features.
