Temu's no-source model is different from the shipping methods of traditional e-commerce platforms. On the Temu platform, merchants can choose two different modes for shipping: JIT (Just-in-Time) mode and VMI (Vendor Managed Inventory) mode.

1. **JIT mode**: In this mode, merchants deliver the goods to Temu's designated warehouse within two days after receiving the order. This is equivalent to a pre-sale model of "order first, then ship". Merchants can deliver the goods to the warehouse by themselves or ship them through express delivery services.

2. **VMI mode**: This model requires merchants to prepare the goods first and then send the goods to Temu's warehouse. Only when the goods are completed in the warehouse will they appear on the buyer's front page for sale. This model is suitable for merchants who need to prepare inventory in advance. It requires merchants to conduct effective inventory management to avoid out-of-stock situations.

In the no-source model, merchants do not need to own actual inventory or goods. Instead, the Temu platform acts as a bridge between buyers and sellers. Buyers place orders and pay through the platform, and then sellers purchase from suppliers and ship directly to buyers. The advantages of this model are that it reduces costs and risks, improves operational efficiency, and allows merchants to expand product categories and increase business opportunities.

The implementation process of the no-source model includes the following steps:

- Finding partners: Establish a cooperative relationship with suppliers, sign an agreement and determine the purchase price and delivery cycle.

- Register and open a store: Register and open a store on a cross-border e-commerce platform, and complete relevant certification and qualification applications.

- Product selection and listing: According to market demand and competition, select suitable products and list them on your own independent station and cross-border e-commerce platform.

- Order acceptance and payment: After the product is ordered on your own independent station or cross-border e-commerce platform, place an order and pay the supplier in time.

- Logistics and delivery: The supplier delivers according to the order information, and the seller is responsible for tracking the logistics situation and updating the buyer in time.

- After-sales service: The seller is responsible for handling the buyer's returns and complaints to protect the buyer's rights and satisfaction.

In general, Temu's no-source model allows merchants to sell goods without the need for actual inventory, thereby reducing inventory costs and risks, while also improving operational efficiency.
