There have always been two viewpoints about after-sales service. Some think it is critical to the survival of company, while others regard it as an extra burden.
Sales expert Yuan Yiping once pointed out that flattering when selling a product is not better than attentive services after the deal, which can show the importance of after-sales service.
A quote made by Joe Girardi says that,"A real selling activity is mean to be after the deal, rather than before one. Sale is a successive process. The end of tens of deals may become the beginning of the next one." Caring your customer after the deal gains trust from exsiting customers as well as attention from potential ones. And this will result in business expansion and increasing customers.
