Bigcommerce is a service offering software that allows you to build an eCommerce website and manage an eCommerce website. It is similar to Magento except that it is smaller and cheaper than using Magento. What sets it apart from other programs is that it offers you a single place to conduct your sales, such as using Bigcommerce to sell on eBay, Facebook, Amazon and Pinterest. The Bigcommerce selling hub works on mobile and desktop devices, and there are conversion tools you can play with that may help you drive more traffic to your sales adverts.
