A positive working capital cycle balances incoming and outgoing payments to minimize net working capital and maximize free cash flow. For example, a company that pays its suppliers in 30 days but takes 60 days to collect its receivables has a working capital cycle of 30 days. This 30-day cycle usually needs to be funded through a bank operating line, and the interest on this financing is a carrying cost that reduces the company's profitability. Growing businesses require cash, and being able to free up cash by shortening the working capital cycle is the most inexpensive way to grow. Sophisticated buyers review closely a target's working capital cycle because it provides them with an idea of the management's effectiveness at managing their balance sheet and generating free cash flows.
