Understanding DSO Meaning: Improving Days Sales Outstanding

Updated on 18 February 2025
Days Sales Outstanding (DSO) is a critical financial metric that helps businesses assess the efficiency of their accounts receivable processes. It measures the average time taken to collect payments from customers, directly impacting cash flow and overall financial health. This article explores what DSO is, how to calculate it, and strategies for improvement, including the role of Allianz Trade’s trade credit insurance solutions in mitigating credit risks.

Summary

DSO refers to the average number of days it takes a company to collect payment after a sale. A lower DSO indicates faster payment collection, contributing to healthier cash flow. If your DSO is 32, for instance, it means you receive payments on average 32 days after a sale.

For businesses offering trade credit, monitoring DSO is essential. A high DSO may signal inefficiencies in collection or potential credit risks. By incorporating DSO analysis into broader financial planning, businesses can optimize cash conversion cycles and improve liquidity management.

To calculate DSO for a given period:

DSO = (Accounts Receivable / Total Sales) * Number of Days

For example, if a company records €50,000 in sales with €35,000 in accounts receivable at month-end, its DSO calculation is:

(35,000 / 50,000) * 31 = 22.3 days 

This means the company collects payments, on average, within 22 days. Importantly, DSO calculations only account for credit sales, excluding cash transactions.

DSO is often compared with Days Payable Outstanding (DPO), which measures how long a company takes to pay its suppliers.

DPO = (Accounts Payable / Cost of Goods Sold) * Number of Days

For instance, a company with €280,000 in costs of goods sold (COGS) and €30,000 in accounts payable at year-end would have:

(30,000 / 280,000) * 365 = 39.1 days 

This means it takes approximately 39 days to settle supplier payments. Comparing DSO vs. DPO helps businesses balance cash inflows and outflows effectively.

DSO is a key element of working capital management, affecting both liquidity and operational efficiency. A high DSO ties up capital in receivables, reducing free cash flow. Conversely, a lower DSO enhances financial flexibility, allowing businesses to invest in growth opportunities.

Efficient receivables management, including proactive follow-ups and streamlined invoicing, helps lower DSO and sustain cash flow stability. Trade credit insurance, such as solutions offered by Allianz Trade, further safeguards businesses against late payments and customer defaults, ensuring financial resilience.

Understanding DSO trends is crucial for assessing business performance: 

  • Increasing DSO may indicate delayed payments or growing credit risks. 
  • Stable DSO suggests consistent cash flow management. 
  • Declining DSO reflects efficient collections and enhanced liquidity. 

For example, Company A expanding into international markets might see DSO rise from 10 to 15 days, due to longer payment cycles abroad. Company B, with an established customer base and a consistent one-month payment term, maintains a steady 30-day DSO. 

Benchmarking DSO against industry and country averages provides insights into competitive positioning: 

  • Global DSO average (2020): 66 days (Bloomberg) 
  • Highest DSO sectors: Machinery (92 days), Construction (82 days), Electronics (77 days) 
  • Lowest DSO sectors: Retail (26 days), Agrifood (43 days), Transportation (47 days) 
  • Longest DSO by country: China (94 days), Italy (88 days), Greece (84 days) 
  • Shortest DSO by country: New Zealand (40 days), Netherlands (45 days), Finland (46 days) 

Before entering new markets, businesses should analyze regional payment behaviors to adapt credit policies accordingly. 

Businesses should tailor credit control policies to maintain an optimal DSO, balancing financial security and competitive payment terms. Key factors to evaluate include: 

  • Customer creditworthiness: Assess payment history and financial stability. 
  • Working capital trends: Monitor changes in cash reserves and liabilities. 
  • Delinquent DSO tracking: Identify late payments and high-risk accounts. 

Incorporating financial ratios like current and quick ratios helps in maintaining financial equilibrium while optimizing DSO. 

To enhance cash flow and reduce DSO, businesses can implement: 

  • Negotiating better payment terms: Shorten payment deadlines, offer early payment incentives. 
  • Strengthening invoicing processes: Ensure invoices are timely, accurate, and contain complete information. 
  • Optimizing accounts receivable management: Invest in payment tracking, debt collection strategies, or leverage trade credit insurance.

Allianz Trade’s trade credit insurance provides an added layer of protection, ensuring stable DSO by: 

  • Mitigating default risks: Coverage against customer non-payment due to insolvency or delayed payments. 
  • Enhancing credit risk assessments: Access to in-depth credit evaluations and financial insights. 
  • Supporting financing opportunities: Trade credit insurance enables businesses to secure better loan terms from financial institutions. 

By leveraging trade credit insurance, companies can proactively manage credit risks, safeguard revenue streams, and maintain financial stability even in unpredictable market conditions. 

Rather than solely aiming to lower DSO, businesses should maintain control over it. A rising DSO signals weak invoicing and debt collection processes, impacting financial health. Constant monitoring, proactive strategies, and trade credit insurance ensure DSO remains stable while preserving strong customer relationships.
