Prestashop is an eCommerce platform with good templates and easy cataloging abilities. However, it depends on a lot of add-on modules that cost a lot to buy and incorporate in the site, making it expensive to add functionality. Further, it requires ample amount of expertise to make it run smoothly from the start, and also to customize and edit the site. So, if you are searching for an alternative that provides a lot of built-in features, easy-to-use interface with excellent customization, then BigCommerce will be a good choice.
