Supply chain companies have existed for a long time, and now they are important participants in the domestic import and export market, and their market position plays an important role. The original forms of supply chain companies are customs declaration agents and freight forwarders. To be a customs broker is to be a customs broker. Small and medium-sized enterprises in the market are very import and export. Because there is no import and export business license, they often find customs brokers (companies) with import and export business licenses to declare customs. For example, many small and micro enterprises engaged in electronic components trade import from abroad and import domestic sales through customs declaration banks. Many export-oriented small and micro enterprises also do not have export business licenses, and export customs declaration is carried out through customs declaration companies. The freight forwarding company's business is mainly to act as an agent for domestic logistics and book the export of marine cabins. Many small and medium-sized import and export trading companies entrust domestic logistics and international maritime logistics to freight forwarding companies.

With the development of business and the accumulation of resources, some customs brokers and freight forwarding companies have integrated their business into comprehensive services, and then evolved into supply chain companies. Some supply chain companies have developed well, accumulated a lot of import and export business information and resources, and then integrated upstream and downstream resources of some industries to become middlemen. For example, in the electronic components industry, supply chain companies have obtained a lot of information about foreign manufacturers by acting as agents for a large number of domestic companies. In the later stage, if domestic electronics manufacturers need to import foreign electronic components and materials, they only need to contact the supply chain company directly to obtain foreign sources of goods, without looking for them themselves, thus saving business costs. Because the database of supply chain companies has accumulated a lot of information about foreign electronic component suppliers, it is easy to provide the supply information of domestic manufacturers. Take another example, an industry of national economy and people's livelihood, imported meat products industry. China is a big importer of meat products, and there are a large number of large and small distributors in China. Frozen meat is imported from foreign farms or meat products manufacturers and sold to the domestic market, including supermarkets, hotels, agricultural products markets and so on. At present, there are several large supply chain platforms in this industry, which specialize in serving domestic distributors. These supply chain companies have obtained the resources of foreign exporters (farms or meat producers) by serving a large number of domestic distributors. In the later stage, domestic distributors no longer need to directly connect with foreign exporters, but only need to tell the supply chain platform what meat needs to be imported, and the supply chain company can provide superior goods.

With the expansion of business, many domestic manufacturers are facing the pressure of liquidity shortage, and supply chain companies have found a business opportunity, that is, to provide accounting period for manufacturers. As an import agent, the supply chain company pays the foreign suppliers and gives the manufacturers a credit period (such as 1-3 months). Domestic manufacturers can get the goods first, 1 and then pay them to the supply chain company after 3 months. Through the credit period, the financial pressure of domestic manufacturers was alleviated and the business volume was expanded. Of course, this kind of business is based on the trust of supply chain companies in manufacturers. Through long-term cooperation, supply chain companies evaluate the credit of manufacturers and give them a payment period. In this way, the supply chain company has formed a new business point, that is, charging interest during the credit period.

As we all know, the profit rate of lending business is very high. What's good about a loan business without a loan license? Driven by profits, supply chain companies focus on account lending business and sort out their business model, namely financing supply chain. At present, the main profit source of most supply chain companies is basically supply chain financing business. Many supply chain companies have set up internal financing departments, poached many bank employees, and conducted risk assessment on internal supply chain business.

Now supply chain companies in the market focus on specific industries and become technology platform companies through big data technology. Such as the imported meat industry mentioned above. There are several large imported frozen meat supply chain companies in China, which have developed into a platform service model because of professional and big data blessing. Platform companies set up websites or apps to integrate agent customs declaration, freight logistics, foreign manufacturer information, foreign exchange market prices (import and export companies settle in foreign currency, and foreign exchange fluctuations have a great impact on profits), and even commodity futures information into comprehensive data, and provide real-time information on the websites or apps. Through the professional services provided by big data, we will deepen cooperation with customers and provide supply chain financing business.
