E-commerce platforms are designed to allow you to manage and sell your products online, and for the most part they do this well. However most platforms fall short when it comes to managing non product information, the type of content you would usually create using a Content Management System.
A common solution to this problem is to split your e-commerce store from your main website, either using a subfolder (e.g. www.yoursite.com/store/) or a subdomain (e.g. store.yoursite.com). This will allow you to use a fully featured Content management system for all of your website content, and a fully featured e-commerce platform to allow you to sell online.
