The BigCommerce AliExpress Dropshipping app allows merchants to import products from AliExpress into their BigCommerce store. This allows merchants to sell products without having to manage inventory themselves. When an order is placed in the BigCommerce store, merchants can place a single-click order on AliExpress to fulfill the order. Merchants can also update product prices and details directly within BigCommerce. The app includes features for importing products, placing AliExpress orders, and viewing orders and products.
