Cash-to-Cash Cycle: Definition, Calculation, and Optimization in Procurement
March 30, 2026
The cash-to-cash cycle is a key metric in working capital management that measures the time between cash outflows for raw materials and cash inflows from sales. This metric shows how efficiently a company manages its tied-up capital and has a significant impact on liquidity. Below, learn how the cash-to-cash cycle is calculated, which optimization approaches exist, and how procurement departments can contribute to improvement.
Key Facts
- Calculation: Days Inventory Outstanding + Days Sales Outstanding - Days Payable Outstanding
- Shorter cycles mean less tied-up capital and better liquidity
- Typical values vary significantly by industry (30-120 days)
- Procurement can optimize through payment terms and supplier management
- Direct impact on the company's cash flow and financing costs
Content
Definition and significance of the cash-to-cash cycle (metric)
The cash-to-cash cycle quantifies the period between cash outflows for material purchases and cash inflows from customer sales.
Basic components
The metric consists of three essential elements:
- Days Inventory Outstanding (DIO) (DIO): inventory holding period
- Days Sales Outstanding (DSO) (DSO): receivables collection period
- Days Payable Outstanding (DPO) (DPO): payables period
Cash-to-cash cycle vs. operating cycle
While the operating cycle includes only DIO and DSO, the cash-to-cash cycle also takes supplier payment deferrals into account. This makes it the more precise metric for actual working capital management.
Importance in procurement
Procurement departments directly influence the cash-to-cash cycle through the negotiation of payment terms, Supplier Score, and inventory optimization. Strategic sourcing can significantly reduce capital commitment.
Measurement, data basis, and calculation
Calculating the cash-to-cash cycle requires precise financial data and a systematic approach to data collection.
Calculation formula
Cash-to-Cash Cycle = DIO + DSO - DPO. All components are expressed in days:
- DIO = (Average inventory / Cost of sales) × 365
- DSO = (Average receivables / Revenue) × 365
- DPO = (Average payables / Cost of sales) × 365
Data sources and quality
Reliable calculations are based on current balance sheet and income statement data. ERP systems provide the necessary information on inventories, receivables, and payables. The Three-Way Match Rate significantly affects data quality.
Reporting and monitoring
Regular monitoring usually takes place monthly or quarterly. Dashboard solutions enable real-time analyses and trend tracking. Integration with Spend Under Management systems improves the informative value.
Interpretation & target values for the cash-to-cash cycle
Assessing the cash-to-cash cycle requires industry-specific benchmarks and a differentiated view of the influencing factors.
Industry-specific target values
Manufacturing companies typically achieve 60-90 days, while trading companies often aim for 30-60 days. Negative values are possible in fast-moving industries. Inventory Turns significantly influence the target values.
Performance indicators
Improvements of 5-10 days per year are considered ambitious but achievable. Quarterly fluctuations below 15% indicate stable processes. On-Time Delivery (OTD) should remain above 95% despite optimization.
Monitoring and control
Trend analyses over 12-24 months identify structural improvements. A segmented view by product groups enables targeted measures. Integration with Service Level prevents one-sided optimization.
Risks, dependencies, and countermeasures
Optimizing the cash-to-cash cycle involves various risks that can be minimized through appropriate measures.
Liquidity risks
Aggressive optimization can lead to liquidity bottlenecks. Excessive inventory reduction jeopardizes On-Time Delivery and delivery capability. Risk management requires balanced buffer stocks and diversified financing sources.
Supplier relationships
Extended payment terms can strain supplier relationships and reduce Delivery Release Adherence. Smaller suppliers are particularly at risk. Transparent communication and fair conditions preserve long-term partnerships.
Operational dependencies
A strong focus on cycle optimization can limit operational flexibility. Seasonal fluctuations and market volatility require adaptable strategies. Complaint Rate may rise due to quality compromises.

Practical example
A mechanical engineering company reduced its cash-to-cash cycle from 85 to 65 days through strategic measures. The procurement department negotiated payment terms from 30 to 45 days and implemented a supplier evaluation system. At the same time, the company optimized inventory management through better demand forecasts.
- DPO extension by 15 days through payment term negotiations
- DIO reduction by 8 days through inventory optimization
- DSO improvement by 3 days through more efficient receivables management
Current developments and impacts
Digitalization and changing market conditions are shaping the evolution of cash-to-cash cycle management in modern companies.
Digital transformation
AI-supported systems automatically optimize cash flows and inventories. Predictive analytics improve Forecast Accuracy and reduce capital commitment. Machine learning identifies optimization potential in real time.
Supply chain finance
Innovative financing solutions such as reverse factoring extend payment terms without burdening suppliers. Dynamic discounting enables flexible use of cash discounts. This makes the Early Payment Discount Rate strategically controllable.
Sustainability and ESG
ESG criteria are increasingly influencing supplier selection and payment terms. Sustainable procurement can justify longer cash-to-cash cycles. Supplier Performance Evaluation increasingly integrate sustainability aspects alongside financial metrics.
Conclusion
The cash-to-cash cycle is a key control metric for efficient working capital management. Procurement departments play a key role in optimization through payment term negotiations and supplier management. Successful companies balance cycle improvements with operational stability and sustainable supplier relationships. Digitalization opens up new optimization opportunities through AI-supported analyses and innovative financing solutions.
FAQ
What is a good cash-to-cash cycle value?
A good value depends heavily on the industry. Manufacturing companies typically achieve 60-90 days, while trading companies aim for 30-60 days. Negative values are possible in fast-moving business models and indicate very efficient working capital management.
How can procurement improve the cash-to-cash cycle?
Procurement optimizes the cycle by negotiating longer payment terms, strategic supplier selection, and inventory management. Cash discount optimization, supply chain finance solutions, and improved demand forecasting also contribute to improvement.
What risks does aggressive cycle optimization entail?
Excessive optimization can lead to liquidity bottlenecks, deteriorated supplier relationships, and reduced safety stocks. This jeopardizes delivery capability and can cause higher long-term costs than the financing costs saved.
How often should the cash-to-cash cycle be measured?
Monthly measurements enable timely management actions, while quarterly analyses are sufficient for strategic decisions. Continuous monitoring through dashboard solutions provides the best transparency for operational and strategic decisions.
