Finance function is the most important function of a business. It is connected to all business activities like production and marketing. There are four major finance functions: (1) Investment decisions about long-term assets. (2) Finance decisions about capital structure and sources of funds. (3) Liquidity decisions about managing current assets and working capital. (4) Dividend decisions about how much profit to distribute to shareholders versus retain. The finance manager plays a vital role in all financial decision making.
