Working capital represents a company's liquidity and is calculated as current assets minus current liabilities. It reflects a company's ability to pay off short-term debt obligations and covers operational expenses. Positive working capital is needed to ensure companies can continue operating without issues. The management of working capital involves managing inventory levels, accounts receivable, accounts payable, and cash to optimize current assets and liabilities and free up cash flow. Companies aim to reduce their working capital cycle by collecting from customers quicker or stretching out payments to suppliers in order to free up more cash.
