Days Sales Outstanding (DSO) is a measure of the average number of days it takes a company to collect its accounts receivable. It is a commonly used metric for evaluating the effectiveness of a company's accounts receivable management.

To calculate DSO, the following formula is used:

DSO = (Accounts Receivable / Total Credit Sales) x Number of Days in Period

Where:

• Accounts Receivable = Total amount of accounts receivable outstanding at the end of the period
• Total Credit Sales = Total amount of credit sales made during the period
• Number of Days in Period = Number of days in the period being measured (usually a quarter or a year)

The resulting number represents the average number of days it takes for a company to collect payment on its accounts receivable. A lower DSO indicates that a company is collecting payment more quickly, while a higher DSO indicates that a company is taking longer to collect payment.

DSO is an important metric for evaluating the effectiveness of a company's accounts receivable management, as it provides insights into how quickly a company is able to convert its outstanding invoices into cash. A high DSO can indicate problems with billing or collection processes, as well as a higher risk of bad debts. A low DSO, on the other hand, can indicate efficient billing and collection processes, as well as a lower risk of bad debts.

Overall, DSO is a useful tool for evaluating the effectiveness of accounts receivable management and identifying areas for improvement. By tracking DSO over time and comparing it to industry benchmarks, companies can improve their cash flow, reduce the risk of bad debts, and maintain positive relationships with their customers.
