When is it appropriate to use a person's first name in a business setting?

In a business setting, it is generally appropriate to use a person's first name when they invite you to do so. This practice demonstrates a respect for personal boundaries and acknowledges the formality that often exists in professional relationships. By waiting for an invitation to use a first name, you allow the other person to dictate the level of familiarity they are comfortable with, which can vary based on company culture, industry standards, and individual preferences.

Using a first name prematurely can come across as overly familiar or even disrespectful, especially in hierarchical or formal business environments. Maintaining professionalism by addressing individuals by their last names or titles until you are invited to use their first name reflects an understanding of etiquette and respect for the professional relationship.
