C stands for customer, that is, individual consumers. Based on whether the starting point and end point of e-commerce are enterprises or individuals, the e-commerce model can be divided into several types, such as BtoB, BtoC, and CtoC.

In the BtoB field, Ciso has become an Internet upstart by engaging in trade between enterprises, and the domestic site Alibaba is also a leader in this regard; at present, the most common model is still the BtoC model, and the famous online bookstore Amazon and the domestic e-commerce company 8848 we mentioned earlier all adopt this model; eBay, which is engaged in online auctions, has built a sales model between consumers, that is, the CtoC model, and domestic Yabuy and Eachnet also follow this model.
