Step-by-step explanation:
When dealing with long-term customers, the aspect of providing quality service that is of special importance is establishing a good reputation. One critical way to do this is by ensuring that every interaction with the customer reflects a high level of professionalism and resourcefulness. Being professional garners positive feedback and resourcefulness creates solutions to customer needs, both of which lead to a strong reputation. This can result in repeat business and positive word-of-mouth referrals. Furthermore, customers who trust in a company's reputation are less concerned about receiving poor-quality products, which can translate to the ability to charge premium prices and improved customer loyalty.
