Expand your digital storefront by having the ability to sell online. You can sell simple products (water bottle, etc), configurable products, or digital downloads. With the addition of the e-commerce section, your site will function and have all of the capabilities of a regular website. Depending on the nature of your business, e-commerce websites are a fantastic way to grow your business.
WooCommerce, a Wordpress e-commerce plugin, is a great option for a basic ecommerce site or an ecommerce site on a budget or tight deadline. You can quickly set up a store to sell anything from downloads to complex products. WooCommerce's base configuration can handle taxes, shipping, and even inventory management.
If you are looking for a more custom platform or something that is not on Wordpress, there are alternates to WooCommerce such as Ewcid, FoxyCart, and CraftCMS.
