OpenCart is a free open source shopping cart from which you can build an online store. Opencart has the standard functionality of an out-of-the-box web store but can be customized through third-party extensions. While the basic platform is free, extensions may need to be purchased.
Sellercloud integration enables you to connect to your web store for all standard operations, like posting products, updating inventory and price, and managing orders. If you have extensions for additional functionality, Sellercloud may be able to work with those as well. Please be advised that customization rates may apply for integration with OpenCart extensions.
