# What is days sales outstanding?

Glossary

Days sales outstanding, or DSO, is the average number of days it takes a business to collect payment after a sale is made. A lower number means customers are paying faster and cash is coming in sooner.

Updated September 2026

## How days sales outstanding works

DSO is calculated by dividing accounts receivable by total credit sales for a period, then multiplying by the number of days in that period. It gives a single number that summarizes how efficiently a business turns sales into actual cash, rather than just looking at the outstanding balance in isolation. Some businesses calculate DSO monthly, while others use a rolling three month average to smooth out seasonal swings in sales.

Businesses track DSO over time to spot trends: a rising number can signal weaker collections or more customers paying late, while a falling number usually means collections are improving. DSO is also compared against a company's own payment terms; a business that offers 30 day terms but has a DSO of 55 has a clear collections problem. Comparing DSO against industry benchmarks also helps a business understand whether its collection performance is typical or needs real improvement.

## Example

A business has $90,000 in accounts receivable and $900,000 in credit sales over a 90 day quarter. DSO equals $90,000 divided by $900,000, times 90 days, which equals 9 days. Since the business offers 30 day payment terms, a DSO of 9 days shows customers are paying well ahead of schedule.

## Days sales outstanding in QuickBooks Online vs Xero

Not software-specific: QuickBooks Online and Xero both provide the raw data, accounts receivable balance and sales totals, needed to calculate DSO, but neither displays the DSO metric directly on a standard report. Many businesses calculate it in a spreadsheet or a connected reporting and dashboard tool each month. Because DSO depends on both receivables and sales figures, keeping both accurate in the books is essential for a meaningful number.
