B2B refers to the business relationship established between merchants.

For example, we can only buy Coca-Cola in McDonald's because McDonald's and Coca-Cola are business partners.

Merchants establish business partnerships in the hope of forming a complementary development opportunity through what everyone provides, so that everyone's business can be profitable. Examples: Alibaba, Huicong.

The B2B model is the longest-standing and most well-developed business model in e-commerce, which can quickly bring profits and returns. Its profits come from the cross-industry transaction integration organization brought about by relatively low information costs, and timely online procurement and supply operators.

The B2B e-commerce model mainly has the advantages of reducing procurement costs, reducing inventory costs, saving turnover time, and expanding market opportunities.
