What is Days Sales Outstanding?
Days Sales Outstanding (DSO) is a financial metric that measures how long it takes a business to collect payment after a sale has been made. It tells you the average number of days your accounts receivables remain unpaid.
In simple terms, it shows how quickly or slowly your customers are paying their invoices.
- DSO is commonly used to evaluate the efficiency of a company’s credit and collections departments.
- It is a key indicator of cash flow health.
“DSO is the pulse of your cash flow. If it’s too high, your business could face liquidity issues—even if your sales are booming.” – Mr Rahman, CEO, Oflox®
Why is DSO Important?
Understanding what is days sales outstanding helps you evaluate how well your business manages credit sales and collections.
Here’s why it matters:
- Cash Flow Management: A high DSO can signal cash flow problems. A low DSO means quick payments and healthy liquidity.
- Operational Efficiency: It shows how efficiently your team handles collections.
- Customer Credit Risk: It highlights potential problems with customer payment behavior.
- Financial Planning: DSO data helps forecast revenue inflows and plan investments better.
How to Calculate Days Sales Outstanding?
The formula for DSO is:
DSO = (Accounts Receivable / Total Credit Sales) × Number of Days
Step-by-Step Breakdown:
- Accounts Receivable: The money owed to your business at a specific time.
- Credit Sales: Total sales made on credit (excluding cash sales) in that period.
- Number of Days: The period you want to measure, typically monthly or quarterly.
Real-Life Example of DSO Calculation
Let’s say:
- Accounts Receivable = ₹3,00,000
- Total Credit Sales for the month = ₹9,00,000
- Number of Days = 30
Using the formula:
DSO = (3,00,000 / 9,00,000) × 30 = 10 days
This means, on average, your business collects payments in 10 days.
Ideal DSO Benchmarks by Industry
Not all industries have the same DSO benchmarks. Here’s a quick snapshot:
| Industry | Average DSO (Days) |
|---|---|
| Software as a Service | 40–50 days |
| Manufacturing | 35–45 days |
| Retail | 20–30 days |
| Construction | 60–90 days |
| Healthcare | 45–60 days |
Note: Always compare your DSO with your industry peers for accuracy.
High DSO vs. Low DSO: What It Means
↑ High DSO
- Customers are taking longer to pay.
- May cause cash flow problems.
- Often linked to weak credit policies or lax follow-ups.
↓ Low DSO:
- Faster payments from customers.
- Stronger liquidity and better business health.
- Shows effective credit and collection processes.
How to Reduce Your DSO?
Improving your DSO means getting paid faster. Here’s how:
- Invoice Promptly: Send invoices immediately after a sale is made.
- Set Clear Payment Terms: Define due dates clearly (e.g., Net 15, Net 30).
- Offer Incentives: Provide early-payment discounts to encourage faster payments.
- Automate Reminders: Use accounting software to automate payment reminders.
- Enforce Late Fees: Charge a late payment fee to motivate timely payments.
- Review Customer Credit: Check creditworthiness before extending credit.
