AliExpress is a cross-border e-commerce platform under Alibaba. It mainly provides the following two supply models:

1. Self-supply model: Merchants can purchase goods and store them in their own warehouses, and then sell them to global buyers through the AliExpress platform. In this model, merchants need to handle the purchase, storage, and delivery of goods by themselves, and bear the corresponding risks and responsibilities.

2. Consignment supply model: Merchants can choose to sign a consignment agreement with suppliers and add the supplier's product list to their own AliExpress store for sale. When a buyer places an order, the merchant will confirm the order and ship it with the supplier. In this model, the supplier is responsible for the purchase, storage and delivery of goods, while the merchant is responsible for promotion and after-sales service. The two share the sales profit in a certain proportion. Different supply models are suitable for different merchant needs and resource conditions. The self-supply model allows merchants to have more control and flexibility, but they need to bear more operational and management responsibilities; the consignment supply model allows merchants to focus more on promotion and after-sales service, reducing inventory risks and logistics costs.
