After sales service is the most important part of after-sales service. After sales service has become an important element for enterprises to maintain or expand market share (such as Shuda, tmall, JD, etc.). The quality of after-sales service can affect consumers' satisfaction. At the time of purchase, the warranty, after-sales service and other relevant provisions of the goods can enable customers to get rid of their doubts and vacillations and make up their minds to purchase the goods. High quality after-sales service can be regarded as the product of brand economy. In a society with fierce market competition, with the improvement of consumers' awareness of safeguarding their rights and the change of their consumption concept, consumers no longer only pay attention to the product itself. When the quality and performance of similar products are similar, they are more willing to choose these companies with high-quality after-sales service.
Objectively speaking, high-quality after-sales service is the product of brand economy, and the after-sales service of famous brand products is often better than that of non brand products. The price of famous brand products is generally higher than that of other brands. On the one hand, it is based on the product cost and quality, and on the other hand, the after-sales service cost has been taken into account in the sales strategy of famous brand products.
