Days Sales Outstanding (DSO)
Days Sales Outstanding (DSO) is a critical financial metric that measures the average number of days it takes a company to collect payment after a sale has been made. For businesses of all sizes, understanding and optimizing DSO can dramatically improve cash flow, reduce financial risk, and enhance overall business health.
What is Days Sales Outstanding (DSO)?
Days Sales Outstanding represents the average number of days it takes your business to collect payment after issuing an invoice. It’s a key accounts receivable (AR) metric that indicates how efficiently your company manages its credit and collection processes.
The DSO Formula:
The standard formula for calculating DSO is:
DSO = (Accounts Receivable ÷ Total Credit Sales) × Number of Days
For example, if your company has $300,000 in accounts receivable and made $600,000 in credit sales during a 30-day period:
DSO = ($300,000 ÷ $600,000) × 30 = 15 days
This means it takes your company an average of 15 days to collect payment after a sale.
DSO vs. Other Collection Metrics
| Metric | What it Measures | When to Use |
|---|---|---|
| Days Sales Outstanding (DSO) | Average time to collect payment | Overall accounts receivable efficiency |
| Average Collection Period (ACP) | Similar to DSO but often calculated using different time periods | Alternative view of collection efficiency |
| Accounts Receivable Turnover | Number of times receivables are converted to cash in a period | Measuring how quickly AR turns into cash |
| Best Possible DSO (BPDSO) | DSO if only current invoices were outstanding | Comparison against actual DSO to identify collection issues |
The Importance of
Managing Days Sales Outstanding
Your DSO metric directly impacts your company’s:

FAQs About
Days Sales Outstanding
The ideal DSO varies by industry, but generally, lower is better. Most businesses should aim for a DSO of 45 days or less. However, industries with longer payment terms may consider 50-60 days acceptable. Compare your performance against industry benchmarks from sources like Credit Research Foundation or industry associations.
Lower DSO can positively impact valuation by demonstrating operational efficiency and reducing perceived risk. Companies with efficient collection processes often command higher multiples because they represent lower risk investments with more predictable cash flows.
The fastest improvements typically come from addressing low-hanging fruit: implementing automated payment reminders, offering additional payment methods, and addressing the specific reasons for your largest overdue accounts. Using invoicing software like InvoiceFly that automates these processes can produce significant DSO improvements within 30-60 days.
During economic challenges, DSO typically increases as customers conserve cash. Prepare by strengthening your collection processes before downturns occur, segmenting customers by risk, and being ready to adjust payment terms for valuable but struggling customers.
Not necessarily. Consider implementing different terms for these customers, such as requiring deposits, offering shorter payment terms, or implementing automatic payment methods. The goal is to manage risk while maintaining valuable customer relationships.
Invoice disputes can significantly increase DSO. Implementing clear documentation practices, getting sign-offs on deliverables, and having a defined dispute resolution process can minimize these delays and improve overall DSO performance.
