CandyPress Store is an eCommerce software suite for small businesses. The application consists of two components: the Front End component, and the Administration component. The Front End component is the virtual storefront for your online store. In other words, it's the part your customer will use to browse your product catalog, place orders, and check out their orders. The Administration component acts as the command center of your online store. Powerful and versatile, yet easy to use and intuitive, it enables you to easily manage and administrate your orders, product catalog, shipping rates, locations, product reviews, and customers.
