Definition: Purchasing key figures
Purchasing KPIs are systematically recorded, measurable indicators for evaluating the performance and efficiency of procurement activities. They serve as a control instrument for purchasing management and enable the objective assessment of processes, suppliers and strategic goals.
Key categories of purchasing indicators
The key performance indicator categories include financial, operational and strategic indicators:
- Key cost figures: Savings, purchasing volume, price variances
- Quality indicators: Complaint rates, delivery quality, failure rates
- Key time figures: Throughput times, delivery reliability, order cycles
- Supplier key figures: Performance evaluation, diversification, compliance
Purchasing key figures vs. general company key figures
In contrast to general company key figures, purchasing key figures focus specifically on order processing and supplier relationships. They take into account procurement-specific factors such as market volatility, supply risks and strategic sourcing decisions.
Importance of key purchasing figures in Procurement
Modern procurement organizations use key figures to optimize their purchasing strategy and demonstrate their value contribution. They enable the identification of improvement potential and support the development of purchasing levers to reduce costs.
Methods and procedures for purchasing key figures
The systematic development and implementation of purchasing KPIs requires structured methods and clear processes. Successful KPI systems are based on defined standards and regular reviews.
Key figure development and selection
Relevant key figures are selected on the basis of strategic objectives and operational requirements. SMART criteria (Specific, Measurable, Achievable, Relevant, Time-bound) are applied:
- Derivation from corporate goals and purchasing strategy
- Consideration of data quality and availability
- Balance between leading and lagging indicators
- Integration into existing reporting structures
Data acquisition and processing
Effective KPI systems are based on reliable data sources and automated recording processes. The integration of different systems such as ERP, goods receipt and supplier evaluation ensures a consistent database.
Benchmarking and target value definition
Target values are defined using internal historical comparisons, industry benchmarks or best practice analyses. Regular calibration and adjustment of the target values ensure the relevance and challenge of the key figures in the dynamic procurement environment.

Key figures for controlling
Effective management of procurement performance requires the definition and monitoring of specific key performance indicators (KPIs). These KPIs enable the objective evaluation and continuous optimization of purchasing activities.
Financial performance indicators
Cost-related KPIs form the foundation of purchasing management and measure direct value contributions:
- Cost savings in absolute terms and relative to purchasing volume
- Maverick buying rate (proportion of non-compliant orders)
- Purchase price variance (price deviations from the standard)
- Cost avoidance (avoided cost increases)
Operational key performance indicators
Process-related KPIs evaluate the efficiency and quality of procurement processes. They include throughput times from the requirement request to the order, delivery reliability and quality rates.
Strategic performance indicators
Long-term KPIs measure the strategic orientation and future viability of procurement. These include supplier diversification, innovation rate by suppliers and sustainability indices. These KPIs support the development of a robust and future-oriented procurement strategy.
Risk factors and controls for key purchasing figures
When implementing and using purchasing KPIs, various risks can arise that impair their informative value and effectiveness. Systematic controls and validation procedures are required.
Data quality and integrity
Incomplete or incorrect data leads to incorrect conclusions and suboptimal decisions. Critical risk factors include:
- Inconsistent data collection between different systems
- Time delays when updating data
- Manual input errors and lack of validation
- Incomplete integration of goods receipt document data
Misinterpretation and overmodulation
Looking at individual key figures in isolation can lead to wrong decisions. Risks arise from one-sided optimization without taking into account the interactions between different performance dimensions and strategic goals.
Manipulation risks and gaming
Key figure-based incentive systems can encourage undesirable behavior. Employees may be tempted to manipulate KPIs or achieve short-term improvements at the expense of long-term goals. Robust control mechanisms and balanced KPI systems minimize these risks through escalation processes and regular audits.

Practical example
A medium-sized mechanical engineering company implements a comprehensive purchasing KPI system to optimize its procurement performance. The company initially defines five core KPIs: cost savings (target: 3% p.a.), delivery reliability (target: 95%), quality rate (target: 99.5%), lead time from requisition to order (target: 5 days) and supplier concentration (max. 30% for top 3 suppliers). Continuous improvements are achieved through monthly monitoring and quarterly supplier meetings.
- Automated data capture from ERP system and supplier portals
- Dashboard-based reporting for management and operational teams
- Regular benchmarking analyses with industry comparisons
Trends & developments in purchasing key figures
Digitalization and the use of advanced technologies are changing the way purchasing KPIs are recorded, analysed and used. New approaches enable more precise measurements and predictive analyses.
AI-supported key figure analysis
Artificial intelligence is revolutionizing the evaluation of key purchasing figures through automated pattern recognition and predictive analyses. Machine learning algorithms identify anomalies and predict developments:
