Americans often converse on a first-name basis in a casual, friendly manner. If an American business person uses a first name in an introduction, it would be considered snobbish and unfriendly not to do the same. If you're unsure of how friendly or formal the situation is (in speech and in writing), use addresses such as Dr., Ms., Miss, Mrs. or Mr., along with the person's last name. If you're unsure of a woman's marital status, use Ms. [miz].

Many Americans are protective of their personal space, so when greeting an American business associate, stand about two feet (60 cm) apart. Avoid close body contact such as hugging and kissing, which Americans consider too personal. Instead, firmly shake hands; the handshake should last approximately one or two seconds. As a friendly gesture, Americans may also pat people on the back while greeting them. While speaking and/or shaking hands, direct eye contact is expected.

Many Americans strongly believe that "time is money." Therefore, it's customary to schedule appointments for any visit to professional offices. Punctuality is essential for both appointments and meetings. If you can't keep an appointment, it's extremely important to call in advance to reschedule the meeting or to notify someone that you'll be late. If you come into a meeting late, you should apologize.

Though the majority of leadership and/or executive positions in American businesses are still held by men, it's becoming more common to meet women in management positions. While conducting business with an American company, expect to interact with women who hold powerful positions.

A guy (singular) is a male person. People use"guys" (plural) here to mean "people" including all members of the team, both male and female. Americans often use this word in informal settings.
