ITM stores are divided into two parts: one is online ITM merchants, and the other is offline ITM stores. ITM merchants apply for individual sellers and shopping malls that open online stores. They only need to apply for the record and become ITM businessmen after examination. There is no cost of a penny, so they want to be online shop merchants, enjoy Sophia's physical store resources in the country, and establish and improve the after-sales service system of online shopping. Compared with traditional retail stores, the profit point earned by ITM stores is service fees. ITM implements online and offline price synchronization and mutual service, so that online shopping consumers can not only buy satisfactory products, but also enjoy the after-sales service of physical stores, which is more humanized. For example, ITM's stores not only help customers avoid the phenomenon of inconsistent pictures and transaction fraud in online shopping, but also set up a "leisure area" for customers to sit and wait for free coffee. This service is now common in VIP banks. ITM shop assistants inspect, trim and package the goods purchased by customers, and then pay after the customers are satisfied, so that ITM stores will charge the sellers a certain service fee. In case of fraudulent transactions such as the picture does not match the real thing, the ITM store will issue a certificate for the customer and coordinate the seller to exchange goods and refund for the customer without any charge. Therefore, ITM model not only establishes and perfects the after-sales service system for e-commerce, but also promotes the informatization process of traditional retail industry, which is a new management concept in the information age.
