Jun 13, 2025
What is Days Sales Outstanding (DSO)?
In the fast-paced business world, liquidity is everything. One of the most important financial metrics that reflects a company's ability to turn sales into cash is Days Sales Outstanding (DSO). Whether you're the Head of Collections, a CFO, or a Collection Agent, understanding DSO is crucial for making informed decisions regarding credit policies and cash flow management.
DSO is the average number of days it takes a company to collect payment after making a credit sale. A lower DSO means quicker collection, which enhances liquidity, while a high DSO could indicate potential problems with the collections process or issues with customer payment behaviors.

Why DSO Matters for Your Business
Understanding and tracking DSO is essential for the financial health of any business. Here’s why:
Cash Flow Health: A higher DSO can lead to liquidity issues, making it difficult for businesses to pay their suppliers, employees, or reinvest in growth opportunities.
Customer Credit Risk: DSO helps identify customers who may be struggling financially or taking longer to pay, giving you insight into potential risk.
Operational Efficiency: DSO measures the effectiveness of your collections process. A high DSO could be a sign that your collection efforts or credit policies need revisiting.
Industry Insight: According to Investopedia, a DSO under 45 days is considered healthy for most businesses. As of Q3 2022, the average DSO across industries was 37.3 days. However, the ideal DSO varies by sector and business model. For example, industries like SaaS and retail often see faster collection cycles, while manufacturing or wholesale companies may face longer DSO times.
How to Calculate DSO
Calculating DSO is straightforward, but it requires accurate data. Use the formula:

Accounts Receivable is the total amount owed by customers at the end of the period.
Total Credit Sales is the amount of sales made on credit (not cash).
Number of Days typically refers to 365 for annual calculations, or you can use 90 or 30 depending on the period you're measuring.
Example Calculation: Suppose your company made $1,500,000 in credit sales over 92 days and has $1,050,000 in accounts receivable.

Interpretation: It takes your company an average of 64.4 days to collect payment after credit sale.
What DSO Numbers Tell You
Low DSO (Under 30 Days): This indicates fast collections, healthy cash flow, and efficient operations.
Moderate DSO (30–70 Days): Common in B2B services, manufacturing, and wholesale. May indicate room for improvement in the collections process.
High DSO (Above 70 Days): A warning sign. High DSO suggests inefficiencies, potential cash flow issues, or lenient credit terms. If your DSO is rising, it may signal a decline in customer satisfaction or ineffective credit policies.
Industry Benchmark: A 2024 Allianz Trade report indicated that the global average DSO is 59 days, but benchmarks vary significantly by industry.
How to Improve Your DSO
Improving your DSO is essential for maintaining healthy cash flow. Here are a few strategies:
Tighten Credit Policies: Screen customers more thoroughly before extending credit, and set clear terms and limits.
Automate Invoicing and Reminders: Use FinanceOps to automate invoicing and follow-ups to ensure timely payments.
Offer Early Payment Discounts: Provide incentives for early payments to encourage quicker cash flow.
Regular Monitoring: Track your DSO monthly and act on upward trends immediately.
Limitations of DSO
While DSO is a valuable metric, it has its limitations:
Not Useful for Cash Sales: DSO only measures credit sales, so businesses with mostly cash transactions will naturally have a lower DSO.
Sensitive to Sales Fluctuations: A sudden spike in sales can temporarily lower DSO, even if collections haven’t improved.
Use in Conjunction with Other Metrics: To get a complete picture of financial health, DSO should be used alongside other metrics like the aging report, delinquent DSO (DDSO), and the cash conversion cycle.
