1. Direct Sellers: In the most common model, businesses sell directly to consumers on their site or through other online marketplaces. Retail titans Nike and Apple operate in this space; eCommerce retail sales alone are expected to reach $4.1 trillion by 2024.
2. B2C Dropshipping: Sellers do not hold inventory but market products shipped straight from the suppliers to the consumers. Because of platforms like AliExpress, the trend has gained a footing for sellers to list and promote products without upfront inventory costs.
3. Online Intermediaries: Portals such as Amazon and eBay connect buyers and sellers while charging a commission for mediating the transaction. Indeed, Amazon has more than 300 million active users worldwide.
