What is Exlcart and how does it function? Exlcart is a software that is open source and can be customized to meet specific requirements. It allows for an unlimited number of vendors to be managed on a single platform and vendors can upload an unlimited number of products. The software provides built-in themes for branding purposes, and users can share their products on social media platforms such as Facebook, Twitter, and Google Plus to boost sales. The use of multi-level categories makes it easier for customers to search for products, and both admins and vendors can keep track of transaction records for future use.
