Writing a development letter to a customer is a way to actively develop a customer. However, the most important form of cross-border business for most companies is for customers to browse the seller’s product pictures and product information and send inquiries to the seller they are interested in. The composition of the cross-border e-commerce B2B inquiry system has been introduced above. The purpose of studying the cross-border e-commerce B2B inquiry system is to check and reply to customer inquiries. Since the quality of the inquiry reply is directly related to whether the order can be successfully completed, after receiving the inquiry, a reasonable analysis should be conducted on the inquiry to determine the reply strategy to successfully obtain the order.

The basic judgment of the type of cross-border e-commerce B2B inquiry refers to the classification and judgment of the inquiry by the salesperson after receiving the customer’s inquiry based on the content of the inquiry and the source of the inquiry. In this way, the salesperson can be more targeted when replying to the inquiry. The classification criteria for cross-border e-commerce B2B inquiries can be the customer’s possible purchase volume, the type of customer company, the customer’s expected transaction speed, the purpose of the customer sending the inquiry, the customer’s country, the customer’s industry, etc. However, no matter what standard is used for classification, the salesperson needs to have the ability to distinguish true and false inquiries. Cross-border e-commerce B2B inquiries can be divided into three basic types based on whether they are real or not: real customers (inquiries), competitors (inquiries), and junk inquiries.
