eBay is a global online marketplace for individuals and businesses, positioned in the C2C/B2C cross-border e-commerce market and comparable to Amazon Marketplace, AliExpress, and similar platforms. Its core capabilities include product listing, search and discovery, auctions and fixed-price purchases, buyer and seller feedback, and connections with payment and logistics processes.

It is not self-hosted software. The deployment requirements mainly involve registration, store setup, and operational compliance, with no need to prepare server resources. Users in China should pay attention to interface and customer-service localization, WeChat ecosystem integration, connections with domestic payment, logistics, and ERP service providers, and cross-border settlement policies.
