Responding to a Client’s Note of Appreciation

Does business etiquette require you to send a “thank-you” letter in response to a letter from a client complimenting you on the service that you have provided them?

The key word in the question is “require.” No, business etiquette wouldn’t require you to send a thank-you note. However, I would certainly recommend it. It’s your opportunity to reach out and touch someone who is satisfied with your work. Writing back will help you build a more solid relationship with this client. That’s why you make the effort; not because business etiquette requires it. Something as simple as this: 

Thank you for your kind words about the service we provide. We take great pride in building the best relationships with all our clients. It’s wonderful to know our efforts are paying off. I hope we can be of service again in the future.
