There are several operational models for cross-border e-commerce platforms. Here are some examples:

1. Direct Purchase Model: This model involves selling products directly to consumers through the platform without any intermediary. The seller sets the prices and takes responsibility for fulfilling customer orders.

2. Dropshipping Model: In this model, the seller does not have physical inventory but sells products on the platform. When a customer places an order, the seller ships the product directly from the supplier. The seller is responsible for handling customer inquiries and returns.

3. Fulfillment by Merchant (FBM) Model: In this model, the seller handles all aspects of the business, including product sourcing, packaging, shipping, and customer service. The seller also takes responsibility for handling returns and refunds.

4. Third-Party Logistics (3PL) Model: In this model, the seller contracts with a third-party logistics company to handle shipping and delivery. The seller is responsible for product listing and sales, while the 3PL company takes care of logistics and returns.

5. Private Labeling Model: This model involves creating and selling products under the brand name of a well-known brand. The seller can use the brand's logo and trademarks to increase credibility and attract customers.

6. Marketplace Model: In this model, the seller lists products on a marketplace platform and receives payment from buyers when the products are sold. The seller takes care of product listing, sales, and customer service.

7. Social Media Marketing Model: In this model, sellers use social media platforms such as Facebook, Instagram, and Twitter to promote their products and interact with customers. They may also offer discounts or promotions to increase sales.

8. Content Marketing Model: In this model, sellers create valuable content related to their products, such as blog posts, videos, and images, to attract and retain customers. They may also offer free samples or limited-time offers to encourage purchases.
