The most popular eCommerce platform options are Open-Source, SaaS (Software As Services) and Headless Commerce.  Open-Source eCommerce Platforms Open-source eCommerce platforms are solutions in which you can modify all aspects of the code.  This type of platform is popular among development organizations seeking to have control over their environment for developing and running an online store, as well as IT teams who want access from anywhere with internet connection. SaaS eCommerce Platforms SaaS eCommerce solutions provide a simpler way to run your online business. With these platforms, you don’t have the hassle of building and developing custom software or an open-source system – they rent their functionality instead! SaaS eCommerce solutions are a cost-effective and practical alternative to open source when you need an online store of your own.  With SaaS platforms, it’s easy for marketers in charge of going market with the company’s products or services quickly because they can affordably set up their own software without having any development costs on top of what already comes out of its monthly fee (which is typically much lower than other options).  Plus updates will be done regularly so there’s no worry about security holes!” Headless Commerce Platforms Headless commerce is a type of CaaS eCommerce in which the shopping cart isn’t connected to your content management system.  This enables brands who use design experience platforms like Adobe Experience Manager or Bloomreach, as well as CMSs such WordPress and Drupal (or any other), plug-in decoupled carts for their online stores with these headless solutions. SaaS technologies are often used in place of decoupled carts due to their low total cost for ownership and high API flexibility. In the past, with on-premise hosting or proprietary platforms builds IT departments at large brands were controllers over business decisions; however as we see more SaaS companies emerge that offer cheaper alternatives.
