Office administration as a job category includes both simple tasks like taking calls and filing paperwork as well as more complex duties like arranging meetings, managing budgets, contacting supply distributors, and liaising with clients. A receptionist greets guests and confirms appointment details. Bookkeepers, or accounts payable personnel, focus on financial aspects of the business by accepting and filing payments. An office manager coordinates schedules of office staff, orders supplies, and coordinates between multiple departments to ensure business objectives are met.
