In the daily research and consultation work, it is often found that many business leaders are often very concerned about how many scales, how much technical equipment, how much capacity, and how much sales, but when they understand the core issue of profit, they shake their heads again and again. However, there are some enterprises in China that hold the infinite pursuit of sales and slam the advertising investment. As a result, the capital chain has been interrupted and it has died down. This kind of sales that only look at the rising sales, not paying attention to profits, often do a lot, but in the end it crashes down. The service is not perfect. The customer is losing a lot. The quality service of many enterprises is just a scorpion. Once they call to find the service personnel, they immediately reply unclear and don't know. This matter has nothing to do with me. This is especially serious in the industry. Some employees may lack corresponding training and supervision. Some employees even think that doing service work is a low-level job. This kind of mentality and concept leads to a large number of customers losing service due to poor service, and the decline in turnover and profits. It becomes inevitable.
