顾客服务是向消费者提供服务前后所采取的一种措施，是销前服务和销后服务之一。 它的重要程度依据产品、种类及顾客群而不同。例如，一个老练的顾客与新顾客相比较可能需要较少 的售前服务（如提供建议等）。在很多情况下，如果所消费的是服务而非产品，那幺顾客服务就显得 更加重要了。

顾客服务可以由人来提供（如：销售员或客户代表）；同时也可以由自助服务来完成，如：网上服务、官方网页网上留言。顾客服务通常是一个企业客户价值体系不可或缺的一部分。

顾客服务的概念是工商业作为竞争优势的增值工具，创建一个顾客服务管理的环境包括战略、过程、组织、动力，并且举办研究去发现顾客事实的需要。

Customer service is the provision of service to customers before, during and after a purchase. The pe****tion of success of such interactions is dependent on employees "who can adjust themselves to the personality of the guest". Customer service is also often referred to when describing the culture of the organization. It concerns the priority an organization assigns to customer service relative to components such as product innovation and pricing. In this sense, an organization that values good customer service may spend more money in training employees than the average organization, or may proactively interview customers for feedback.
