Accounts receivable turnover ratio is a crucial metric in finance that reflects the efficiency of a company's collection process. It measures the number of times a company collects its average accounts receivable balance during a specific period. A higher DSO (Days Sales Outstanding) signifies that a company's receivables, as a percentage of sales, have increased, which may indicate a potential cash flow problem. As a financial professional, it is important to closely monitor this ratio to ensure timely collection and maintain a healthy cash flow for the company.
