What elements does the basic management process of hotel customer service include?

Hello, I'm an analyst at Huaheng Zhixin Human Resources Consulting Company.

Customer service is generally divided into three categories in business practice, namely: pre-sales service, in-sales service and after-sales service. Pre-sales service generally refers to a series of activities provided by enterprises to customers before selling products, such as market research, product design, providing instruction manuals and consulting services. Sales service refers to the services provided by the seller to the buyer in the process of product transaction, such as reception service and commodity packaging service. After-sales service refers to the services related to the products sold and beneficial to the buyer's characteristics, mainly including delivery, installation, product replacement, repair, maintenance, technical training and other services.
