A software platform that allows e-commerce companies to create, edit and publish content on their website with no coding required. Users can change the look and feel of the online store in several ways, including modifying product page layout, adding new sections to promote specific products or services, or adding promotional banners to the site. E-commerce CMS software can be SaaS or cloud-based — which is hosted and managed by the software vendor without a separate server — or open source, which is often self-hosted and gives users total control over the website’s functionality.
