Cash flow impact of payment terms: liquidity management in Procurement
November 19, 2025
The cash flow effect of payment terms describes the direct influence of agreed payment periods on a company's liquidity situation. In Procurement , it Procurement a key tool for optimizing working capital, as longer payment terms reduce capital commitment and create short-term liquidity advantages. Read on to find out how payment terms are used strategically, what methods of evaluation exist, and what risks need to be considered.
Key Facts
- Extending payment terms by 10 days can improve liquidity by several million euros
- Optimal payment terms balance cash flow advantages with supplier relationships and cash discount effects.
- DPO (Days Payable Outstanding) is the most important indicator for measuring the cash flow effect.
- Industry-specific standards significantly influence the scope for negotiation.
- Digital tools enable precise simulation of various payment target scenarios

Definition: Cash flow effect of payment terms
The cash flow impact of payment terms quantifies the financial effect of different payment periods on company liquidity.
Basic mechanisms
Payment terms act as a natural source of financing, as suppliers effectively grant credit. Extending payment terms from 30 to 60 days theoretically doubles the available liquidity from this business. This has measurable effects on working capital management.
Cash flow impact vs. cash discount effects
Optimization requires weighing up the gains in liquidity against the loss of cash discount benefits. A cash discount calculation often shows that a 2% cash discount for 10 days corresponds to an annual interest rate of over 70%.
Importance in strategic Procurement
Modern purchasing organizations integrate payment term optimization into their procurement controlling processes and use it as a negotiating tool for overall cost optimization.
Methods and procedures
Systematic approaches to evaluating and optimizing the cash flow impact of payment terms combine quantitative analyses with strategic considerations.
DPO analysis and simulation
The DPO effect simulation enables the precise calculation of liquidity effects for various payment term scenarios. Purchase volumes, current payment terms, and planned changes are correlated.
Cost-benefit assessment
A structured cost-benefit analysis takes into account not only liquidity effects but also lost discounts, supplier reactions, and risk factors. The evaluation is based on capital costs and alternative financing options.
Supplier segmentation
Different supplier groups require differentiated payment term strategies. Strategic partners are treated differently than commodity suppliers, with bargaining power and dependencies being decisive factors.

Key KPIs for cash flow effects of payment terms
Specific key figures enable precise measurement and control of the cash flow effects of payment terms in Procurement.
Days Payable Outstanding (DPO)
DPO measures the average number of days between invoice receipt and payment. The formula is: (accounts payable × 365) / purchase volume. An increasing DPO indicates improved liquidity, but should be weighed against supplier satisfaction.
Cash flow improvement through payment terms
This key figure quantifies the absolute liquidity gain achieved through payment term optimization. It is calculated from the difference between old and new payment terms multiplied by the average daily purchase. Purchasing controlling uses this key figure to measure success.
discount waiver rate
The proportion of unused discounts in relation to the total purchase volume indicates potential for optimization. A high rate may indicate suboptimal payment term strategies if discount calculation would be more advantageous.
Risks, dependencies and countermeasures
Aggressive exploitation of payment terms carries various risks that must be minimized through appropriate measures.
Supplier relationships and security of supply
Excessively long payment terms can strain supplier relationships and lead to supply bottlenecks. Smaller suppliers are particularly affected, as they often depend on prompt payments. Regular supplier evaluations and open communication are essential.
Liquidity risks with suppliers
Financial difficulties among suppliers can be exacerbated by extended payment terms. Systematic procurement controlling should monitor supplier creditworthiness and identify critical dependencies.
Legal and compliance risks
National and international payment term regulations set limits on how terms can be structured. Violations can lead to penalties and damage to reputation. Continuous monitoring of the legal framework is essential.

Practical example
An automotive supplier with a purchasing volume of €500 million extends its average payment terms from 30 to 45 days. This corresponds to a DPO improvement of 15 days and creates additional liquidity of around €20.5 million (500 million ÷ 365 × 15). At the same time, the company waives a 2% discount on 30% of the volume, which means additional costs of €3 million. The net effect is €17.5 million in additional liquidity with €3 million in additional costs – an attractive financing alternative to bank loans.
- Systematic analysis of all supplier contracts
- Negotiation of differentiated payment terms for each supplier group
- Continuous monitoring of liquidity and cost effects
Current developments and effects
Digitalization and changing market conditions are creating new opportunities for the strategic use of payment terms in Procurement.
AI-supported optimization
Artificial intelligence enables the automated analysis of payment term effects across large supplier portfolios. Machine learning algorithms identify optimal payment term combinations, taking into account multiple factors and restrictions.
Supply Chain Finance Integration
Modern supply chain finance solutions extend traditional payment terms with flexible financing options. Suppliers can choose between immediate payment with a discount or regular payment terms, creating win-win situations.
Regulatory developments
Stricter payment term regulations in various countries are affecting the scope for maneuver. Companies must adapt their strategies to local regulations and minimize compliance risks.
Conclusion
The strategic use of payment terms offers considerable potential for optimizing liquidity in Procurement. Successful companies balance cash flow advantages with supplier relationships and take legal frameworks into account. Systematic analysis and continuous monitoring of the effects are essential for sustainable success. Digitalization opens up new opportunities for precise optimization and win-win solutions with suppliers.
FAQ
How do you calculate the optimal payment terms?
Optimization is achieved by comparing capital costs with cash discount benefits and supplier reactions. If capital costs are lower than the cash discount rate, longer payment terms are advantageous. A detailed cost-benefit analysis also takes qualitative factors such as supplier relationships into account.
What payment terms are customary in different industries?
Industrial companies typically work with 30-60 days, while 90-120 days are often standard in retail. Construction and public sector clients often have longer cycles. Industry standards have a significant impact on negotiating power.
How do extended payment terms affect suppliers?
Longer payment terms increase capital commitment for suppliers and can put pressure on their liquidity. Smaller companies are particularly affected. Transparent communication and fair terms are essential for stable partnerships.
What are the legal limits on payment terms?
The EU Late Payment Directive limits payment terms in the B2B sector to a maximum of 60 days, unless expressly agreed otherwise. National laws may provide for stricter regulations. Violations can result in interest payments and legal consequences.
