Recently, we've just completed the development of a mini - program for a multi - merchant vertical - industry trading platform. Right after its completion, some merchants were eager to settle in. Moreover, several projects we've been communicating about recently are all such vertical business platforms for specific industries. So, I think there is still a relatively high market demand for this kind of vertical platform. That's why today we're going to talk about what functions such a vertical - industry trading platform has. First of all, it requires a merchant management function: Merchants are allowed to register and verify their identities to ensure that the merchants on the platform are legal and compliant. Merchants can edit and update their own information, such as contact details, store description, logo, etc. Merchants can also view, process, and track orders, including order status, order history, etc. Secondly, the service management function: Merchants can release new services, including information such as service name, description, price, and pictures. Merchants can also manage services by category, which is convenient for consumers to browse and filter. Merchants can set up promotional activities, such as discounts, price concessions, etc. Thirdly, the payment and settlement function: The system needs to support multiple payment methods, such as offline transfer payment, WeChat Pay, etc. The platform provides a settlement management function, which settles the sales amount to merchants according to the specified settlement cycle. Fourthly, the user management function: Consumers are allowed to register accounts and log in, and their personal information and order history are saved. Consumers can edit and update their personal profiles, including contact information, basic information, etc. Consumers can also add services to the shopping cart for convenient unified settlement. Fifthly, the search and filtering function: Ensure that products can be indexed by search engines to increase the platform's exposure. Support users to conduct advanced searches through keywords, price ranges, brands, and other conditions. Allow users to filter and sort products according to different conditions, so as to find the required service items more quickly. Sixthly, the communication and evaluation feedback function: Consumers and merchants need a convenient and fast communication platform. Provide online customer service support to solve the problems and doubts that users encounter during the purchase process. At the same time, users are also allowed to evaluate and rate the purchased services for reference by other users. Seventhly, data analysis and encryption: The system provides reports on merchants' sales data to help merchants understand their sales situation and formulate marketing strategies. And set up an encryption mechanism for user data to ensure that users' personal information and transaction data are encrypted and protected, preventing information leakage. Basically, these seven major functions can meet the basic functions of a vertical - industry trading platform. If you have any special functional requirements, we can communicate and customize them. These functions can be customized and expanded according to the platform's positioning and requirements for the multi - merchant platform.
