A Chief Financial Officer (CFO) is the senior offer responsible for overseeing the financial activities of the entire company. Some of the most important duties of the CFO include implementing and supervising internal controls, monitoring cash flow, planning strategic financial decisions, and serving as a key advisor to company management. Ensuring proper accounting and reporting is essential for a successful CFO, as the penalties for not detecting fraudulent activities can be severe. A CFO should have extensive financial management experience as well as educational credentials in finance and/or accounting.
