PolyCommerce is a selling platform plugin that intelligently syncs store listings and orders to marketplaces such as eBay, Amazon, and more. New and existing listings are automatically posted from your selling platform to each marketplace with little intervention required. When a sale is made on a marketplace, PolyCommerce uploads the order to your selling platform and reduces stock across your marketplaces. PolyCommerce currently supports Shopify, BigCommerce and NopCommerce selling platforms.
