I have this problem also, so I am super detailed in my invoice line items so I can go back to other clients and bill appropriately. I have an hourly rate and bill by the quarter-hour. This month is the first time I've encountered someone who balks at the minimum charge invoice line. I politely explained that I provide services for many clients, and they all expect the same level of detail and professionalism. I am a professional and it has taken my time and money to be good at what I do, it has been my experience that if I have to stop my workflow to accept your phone call, especially if I'm not in your books, I have to refocus on your company, your policies, and procedures, your preferences, frequently open your accounts to answer your question, if this takes more than 7 minutes I charge you the 15 minutes; because when you hang up on minute 8, I have to close everything and refocus on the tasks for the client I was working in, why should the work they receive suffer because of me helping you? Please let me know your thoughts.
