Frequently Asked Questions
Common questions about DSO and accounts receivable management
What is Days Sales Outstanding (DSO)?
Days Sales Outstanding (DSO) measures the average number of days it takes a company to collect payment after making a sale. It indicates how efficiently a business manages its accounts receivable and cash flow.
How do I calculate DSO?
DSO is calculated as: (Accounts Receivable ÷ Total Credit Sales) × Number of Days. For example, (Accounts Receivable ÷ Annual Credit Sales) × 365 gives you the annual DSO.
What is a good DSO ratio?
A good DSO varies by industry. Generally, 30-45 days is considered good for most businesses. Lower DSO indicates faster collections and better cash flow. Compare against industry benchmarks.
How can I improve my DSO?
Improve DSO by: offering early payment discounts, implementing stricter credit policies, sending invoices promptly, following up on overdue accounts, and automating collection processes.
What's the difference between DSO and collection period?
DSO and collection period are essentially the same metric. Both measure how long it takes to collect receivables. Collection period is often used interchangeably with DSO.
How often should I track DSO?
Monitor DSO monthly to track collection efficiency trends. Calculate using different time periods (30, 60, 90 days) to identify seasonal patterns and collection issues.
What affects DSO calculation accuracy?
DSO accuracy depends on: using consistent time periods, properly categorizing cash vs credit sales, adjusting for seasonal variations, and excluding bad debt write-offs from calculations.
How does DSO impact business valuation?
Companies with lower DSO are often valued higher because they demonstrate efficient working capital management and have better cash flow predictability for investors and lenders.
