Days Payable Outstanding (DPO): Key figure for optimal payment management
November 19, 2025
Days Payable Outstanding (DPO) is a key financial indicator that shows the average number of days it takes a company to pay its supplier invoices. This key figure plays a crucial role in procurement management, as it has a direct impact on liquidity and supplier relationships. Find out below how DPO is calculated, what strategic advantages an optimized payment period offers and how you can use this key figure successfully in your Procurement .
Key Facts
- DPO measures the average number of days between receipt of invoice and payment to suppliers
- Calculation: (trade payables × 365) ÷ cost of goods sold
- Higher DPO values improve liquidity, but can put a strain on supplier relationships
- Standard industry DPO values vary between 30 and 90 days
- Optimal DPO balances cash flow benefits with supplier satisfaction and cash discount utilization

Definition and meaning of Days Payable Outstanding (DPO)
Days Payable Outstanding is the average period of time in days that a company needs to settle its outstanding liabilities to suppliers.
Basics and core aspects
DPO is one of the most important working capital indicators and shows the efficiency of accounts payable management. The key figure is calculated by multiplying the average trade payables by 365 days and dividing by the annual cost of sales.
- Measurement of payment speed to suppliers
- Indicator for the company's liquidity management
- Basis for negotiations on payment terms
DPO vs. other liquidity ratios
In contrast to Days Sales Outstanding (DSO), which measures the receivables term, DPO focuses on the liabilities side. Together with Days Inventory Outstanding (DIO), DPO maps the cash-to-cash cycle.
Importance of DPO in Procurement
For purchasing organizations, DPO is a strategic management tool for optimizing supplier relationships and working capital. A balanced DPO strategy takes into account both financial benefits and the maintenance of stable partnerships with key suppliers.
Measurement, database and calculation
The precise calculation of DPO requires a solid database and standardized calculation methods in order to achieve meaningful results.
Calculation formula and data sources
The standard formula is: DPO = (average trade payables × 365) ÷ cost of goods sold. The required data comes from the balance sheet (liabilities) and the income statement (cost of goods sold).
- Trade payables (balance sheet date or average)
- Cost of goods sold or cost of sales for the period under review
- Consideration of seasonal fluctuations through quarterly averages
Data quality and cleansing
The basic data must be adjusted for meaningful DPO values. One-off effects, extraordinary payments or deferred income can distort the result. The three-way match rate influences the accuracy of the liabilities recorded.
Benchmarking and comparative values
DPO values should always be viewed in the context of the industry. While retail companies often have DPO values of 30-45 days, industrial companies can reach 60-90 days. The timeliness of payments plays an important role in supplier relationships.

Interpretation & target values for DPO
The correct interpretation of DPO values and the definition of appropriate target values are crucial for successful working capital optimization.
Industry-specific benchmarks
DPO targets vary significantly between industries and business models. While retailers typically aim for 25-40 days, industrial companies may consider 45-75 days to be optimal. The spend-under-management ratio influences the control options.
- Retail: 25-40 days (fast turnover of goods)
- Manufacturing industry: 45-75 days (more complex supply chains)
- Service sector: 30-50 days (lower material intensity)
Identify optimization potential
Analyzing DPO trends and deviations reveals opportunities for improvement. A sudden drop in DPO can indicate liquidity problems, while consistently low values signal untapped optimization potential. The on-time payment rate should not be neglected.
Integration into overall strategy
DPO should not be viewed in isolation, but should be integrated into the overall working capital management strategy. The balance between DPO, DSO and DIO determines the cash conversion cycle and therefore the company's liquidity position.
Risks, dependencies and countermeasures
An unbalanced DPO strategy can entail considerable risks for supplier relationships and operational performance.
Supplier relationships and trust
Excessively extended payment terms can undermine the trust of suppliers and lead to worsened conditions. Critical suppliers could terminate business relationships or demand advance payments. The supplier evaluation should therefore also take payment behavior into account.
- Deterioration in purchasing conditions due to disgruntled suppliers
- Risk of supply bottlenecks for critical materials
- Negative impact on suppliers' willingness to innovate
Financial and operational risks
Excessively aggressive DPO extensions can lead to liquidity problems for suppliers and destabilize the entire supply chain. The complaint rate can increase if suppliers reduce quality under cost pressure.
Compliance and legal aspects
Legal regulations such as the EU Late Payment Directive set limits for payment terms. Violations can lead to interest payments and legal consequences. Transparent contractual compliance is therefore essential for a sustainable DPO strategy.

Practical example
An automotive supplier with an annual cost of goods of 50 million euros and average liabilities of 8 million euros achieves a DPO of 58 days. By implementing a supply chain finance program, the company extends the DPO to 75 days without burdening supplier relationships. Suppliers continue to receive timely payments from the financing bank, while the company gains an additional 17 days of liquidity.
- Liquidity gain: 2.3 million euros in additional working capital
- Maintaining supplier satisfaction through punctual payments
- Reduced financing costs through optimized cash flow management
Current developments and effects
Digitalization and changing market conditions are having a significant impact on the strategic use of DPO in modern procurement management.
Digitization and automation
Modern ERP systems and AI-based solutions enable more precise DPO control through automated payment planning. The level of automation for invoices is continuously increasing and improving the predictability of payment flows.
- Predictive analytics for optimal payment times
- Automated cash discount utilization based on liquidity forecasts
- Real-time DPO monitoring through integrated dashboards
Supply chain finance and dynamic discounting
Innovative financing instruments are changing traditional DPO optimization. Supply chain finance programs make it possible to extend DPO without burdening suppliers. The discount rate is used strategically to optimize costs.
ESG compliance and supplier support
Sustainability aspects are increasingly influencing the DPO strategy. Companies are using shortened payment cycles specifically to support smaller suppliers and strengthen the supply chain. This requires a balance between financial goals and social responsibility.
Conclusion
Days Payable Outstanding is a key performance indicator for successful working capital management in Procurement. The optimal DPO strategy balances financial benefits with stable supplier relationships and takes industry-specific characteristics into account. Modern technologies and innovative financing instruments open up new opportunities for DPO optimization without jeopardizing traditional partnerships. A well thought-out implementation can generate considerable liquidity advantages and at the same time strengthen the competitiveness of the entire supply chain.
FAQ
What is a good DPO value for my company?
An optimal DPO value depends on your industry, supplier structure and liquidity strategy. Industrial companies often achieve 60-90 days, while retailers aim for 30-45 days. It is important to strike a balance between liquidity optimization and supplier satisfaction.
How can I extend DPO without upsetting suppliers?
Transparent communication, supply chain finance programs and selective renewals only with financially stable suppliers are proven strategies. Offer alternatives such as dynamic discounting or early payment programs for smaller suppliers.
What data do I need for a precise DPO calculation?
You need the average trade payables and the annual cost of goods sold. Adjust the data for one-off effects and take seasonal fluctuations into account for meaningful results.
How does a DPO extension affect supplier relationships?
A moderate DPO extension is usually acceptable if it is communicated transparently. However, extreme extensions can lead to worsened conditions, quality problems or even the loss of important suppliers. A balanced strategy is crucial.
