Days Sales Outstanding DSO

Days Sales Outstanding (DSO) is a financial metric that measures the average number of days a company takes to collect payment from its customers after making a sale on credit. A lower DSO indicates faster collection and better cash flow management.

What Is DSO?

DSO = (Accounts Receivable / Revenue) x 365

Or alternatively:
DSO = (Accounts Receivable / Credit Sales) x Number of Days in Period

DSO shows how long credit given to customers remains uncollected on average.

Interpreting DSO

– **Low DSO**: cash is being collected quickly; healthy cash flow
– **High DSO**: customers are slow to pay, or the company has poor collection practices
– **Rising DSO over time**: warning signal of deteriorating customer credit quality or receivables management issues

Industry Benchmarks

DSO varies by industry and customer type:

| Industry | Typical DSO |
|———|————|
| Retail (mostly cash/card sales) | 5-15 days |
| FMCG distribution | 30-45 days |
| IT services (enterprise clients) | 60-90 days |
| Infrastructure/government contracts | 90-180 days |

Government contracts and large enterprise clients often have slower payment timelines.

DSO in the Working Capital Cycle

DSO is one of the three components of the cash conversion cycle:
Working Capital Cycle = DIO + DSO – DPO

Reducing DSO shortens the working capital cycle and reduces the company’s need for external financing.

Practical Example

An IT company has Rs 300 crore in accounts receivable (money owed by clients) and Rs 1,200 crore in annual revenue. DSO = (300 / 1,200) x 365 = 91 days. This means it takes the company about 3 months to collect after billing clients. Improving collection practices to bring DSO to 60 days would free up Rs 100 crore of cash.

Key Takeaways

– DSO = (Accounts Receivable / Revenue) x 365; measures average collection period
– Lower DSO means faster cash collection and better working capital efficiency
– Rising DSO is a red flag indicating collection problems or deteriorating customer credit
– Government and large corporate clients typically have higher DSOs than retail customers
– Reducing DSO improves cash flow and reduces the working capital cycle, decreasing reliance on short-term borrowings
