As an office administrator, you’ll need to do clerical duties alike to those of an administrative assistant. On the other hand, you will also oversee administrative staff and assist with fundamental business management tasks. Similarly, your everyday office administration duties may include greeting visitors, creating checklists and budgets, managing databases, scheduling meetings and appointments for the team, working with documents and spreadsheets, receiving calls, aiding in managing projects, and cleaning the office. This role also involves assigning work to other staffs and, in some cases, to workers in different departments like sales and production.
However, daily job tasks can vary according to the type of company. For example, in a construction firm, you may need to create customer purchase orders, handle bid packages and create project proposals as an office administrator. In contrast, an office administrator at an accounting corporation may concentrate more on bookkeeping duties.
