Working capital management is a tactical focus on maintaining a sufficient amount of working capital to support a business, while minimizing the investment in this area. The core goal in working capital management is to ensure that there is always sufficient cash on hand to pay for liabilities as they come due for payment. Since there can be a high cost associated with the funding of working capital, there is an offsetting pressure to keep funding levels low. This latter goal is achieved by closely monitoring the turnover levels for accounts receivable, inventory, and accounts payable, and taking action when the turnover levels vary from expectations. An additional tool used to monitor working capital levels is the short-term and medium-term cash forecast, which tells management when unusually high or low cash levels are expected.
