User: What does IHAC mean?
Assistant: It is short hand for 'I have a customer.'  This phrase is regularly used in companies that sell products or have a professional services and go to market divisions.  The reason it used is because revenue is generated from customer accounts who use the platform the company is selling.  Account Executives and Solution Architects are assigned to an account, and when they need to make reference to a customer questions or need they may start by saying "IHAC who needs help with this product or service."
