E-commerce is a business activity centered on the exchange of goods using information network technology as a means; it can also be understood as the activities of conducting transactions and related services in the form of electronic transactions on the Internet, corporate intranets and value-added networks. It is the electronicization, networking and informatization of all aspects of traditional business activities. There are several models:

1. E-commerce between enterprises and consumers (Business to Consumer, i.e. B2C).

2. E-commerce between enterprises (Business to Business, i.e. B2B).

3. E-commerce between consumers (Consumer to Consumer, i.e. C2C). The C2C business platform provides an online trading platform for buyers and sellers, so that sellers can actively provide goods for online auctions, and buyers can choose goods for bidding.

4. E-commerce between offline business and the Internet (Online To Offline, i.e. O2O). In this way, offline services can be used to attract customers online, consumers can use online to select services, and transactions can be settled online, and scale can be reached quickly. The most important features of this model are: the promotion effect can be checked and each transaction can be tracked.

5. The so-called BoB is the abbreviation of Business-To-Business, which means a new e-commerce model in which the supplier (Business) and the purchaser (Business) reach a product or service transaction through an operator (Operator).

6. The B2Q model provides pre-sales factory inspection and product inspection, after-sales installation, commissioning and maintenance services by introducing third-party engineer technical service personnel in the procurement process.

Perhaps when we mention the e-commerce industry, the first thing we think of is Taobao, but with the rapid development of the e-commerce industry, more and more platforms have sprung up like mushrooms after rain. For example, "Shop123 E-commerce" provides B2C or B2B e-commerce systems for all industries. No technical background is required, and it is easy to open and operate.
