Inventory procedures: Methods for systematic stocktaking in Procurement
November 19, 2025
Inventory procedures are systematic methods for the complete recording and evaluation of stock levels in companies. They form the basis for precise inventory management and enable well-founded decisions to be made in procurement. Find out below which methods exist, how they are used and what significance they have for modern Procurement .
Key Facts
- Inventory procedures are used to systematically record all stock levels on a specific key date
- Differentiation between key date, permanent and relocated inventory depending on company requirements
- Legal obligation to take an annual inventory in accordance with the German Commercial Code (HGB) for companies required to prepare accounts
- Modern processes use digital technologies such as RFID and barcode scanners for greater accuracy
- Inventory deviations reveal weaknesses in inventory management and warehouse processes

Definition: Inventory procedure
Inventory procedures comprise all systematic methods for the physical recording, valuation and documentation of a company's assets and liabilities at a specific point in time.
Basic types of procedure
The most important inventory procedures differ in terms of timing and implementation:
- Balance sheet date inventory: complete inventory as of the balance sheet date
- Perpetual inventory: continuous recording over the entire financial year
- Postponed inventory: Postponement by a maximum of three months before or two months after the balance sheet date
Inventory procedure vs. inventory management
While inventory management comprises the ongoing documentation of stock movements, stocktaking procedures serve to periodically check and correct these book inventories by means of physical counting.
Importance of inventory procedures in Procurement
For Procurement , inventory procedures provide essential data for inventory optimization and enable the identification of obsolete stocks. They form the basis for strategic procurement decisions and supplier evaluations.
Methods and procedures
The choice of a suitable inventory method depends on the size of the company, the industry and the available resources. Modern approaches combine traditional counting methods with digital technologies.
Inventory sampling and cycle counting
Cycle counting enables a continuous inventory check through regular partial inventories. Items are prioritized according to their value and turnover rate, often based on an ABC-XYZ analysis.
Digital inventory methods
RFID technology and mobile scanner solutions significantly speed up the inventory process. These systems reduce counting errors and enable seamless integration into existing ERP systems for inventory analysis.
Quality assurance during stocktaking
The dual control principle, recounts in the event of deviations and systematic documentation ensure the accuracy of the inventory results. Standardized checklists and training for inventory personnel minimize sources of error.
Tacto Intelligence
Combines deep procurement knowledge with the most powerful AI agents for strong Procurement.
Key figures for controlling inventory procedures
Meaningful key figures enable the evaluation of inventory quality and the continuous improvement of processes. These metrics support strategic decisions in inventory management.
Inventory accuracy and variance analysis
Inventory accuracy measures the proportion of correctly recorded items in the total number. Deviation rates by value and quantity reveal weaknesses. Target values of over 95% accuracy are regarded as a benchmark for professional inventory indicators.
Inventory costs and efficiency
Costs per inventoried item and time spent per item evaluate the cost-effectiveness of different procedures. The relationship between inventory costs and identified stock discrepancies shows the return on investment of quality assurance.
Process quality and throughput times
Average inventory duration, recount rate and correction effort measure process efficiency. These key figures support the optimization of inventory cycles and the evaluation of various process alternatives for operational inventory management.
Risks, dependencies and countermeasures
Inventory procedures involve various risks that can affect the accuracy of inventory data and business continuity. Systematic risk assessment is essential.
Counting errors and data quality
Human error during manual counting can lead to significant stock discrepancies. Inadequate training, time pressure and confusing warehouse structures exacerbate this problem. Standardized processes and double checks minimize these risks.
Business interruptions
Key date inventories often require production stops or stock closures, which can lead to delivery bottlenecks. Planning alternative delivery times and communicating with customers are critical success factors.
Technical dependencies
Digital inventory systems create dependencies on IT infrastructure and software availability. System failures during the inventory can lead to data loss. Backup systems and manual fallback processes are essential security measures.

Practical example
A medium-sized mechanical engineering company introduces a combined inventory strategy: A-items are recorded monthly using cycle counting, B-items quarterly and C-items annually for key date inventory. RFID tags on high-quality components enable automatic stock reconciliation. As a result, the company reduces inventory deviations from 8% to 2% and shortens inventory times by 60%. At the same time, planning accuracy for critical procurement decisions is significantly improved.
- Implementation of risk-based inventory cycles according to ABC classification
- Integration of digital recording technologies to increase efficiency
- Continuous process optimization through key figure monitoring
Trends & developments around inventory procedures
Digitalization is revolutionizing traditional inventory methods and enabling new approaches to stocktaking. Artificial intelligence and IoT technologies are creating innovative solutions.
AI-supported inventory optimization
Artificial intelligence analyzes historical inventory data and identifies patterns in inventory deviations. Machine learning algorithms optimize inventory cycles and forecast critical stock levels for more efficient material planning.
Automated stocktaking
IoT sensors and smart shelves enable continuous, automatic inventory monitoring. These technologies reduce manual effort and significantly improve data quality for inventory management.
Cloud-based inventory solutions
Mobile cloud applications enable decentralized inventories in real time. Teams can work in a coordinated manner across locations, while central dashboards provide immediate insights into inventory progress and results.
Conclusion
Inventory procedures are indispensable tools for precise inventory management and form the foundation of strategic procurement decisions. Digitalization opens up new possibilities for more efficient and accurate inventory processes. Companies should continuously adapt their processes to technological developments and manage them using meaningful key figures. A professional inventory strategy makes a significant contribution to optimizing the entire supply chain.
FAQ
What are the most important inventory procedures?
The three main procedures are the physical inventory as at the balance sheet date (complete inventory as at the balance sheet date), the perpetual inventory (continuous inventory) and the postponed inventory (postponed by a maximum of three months before or two months after the balance sheet date). Each method has specific advantages and disadvantages depending on the company's situation.
How often must an inventory be carried out?
Legally, companies required to prepare financial statements must carry out at least an annual inventory. In practice, many companies also carry out partial inventories or cycle counting during the year in order to continuously monitor inventory accuracy and detect deviations at an early stage.
Which technologies support modern inventory procedures?
Barcode scanners, RFID systems, mobile apps and cloud-based inventory solutions digitize the recording process. These technologies reduce counting errors, speed up data collection and enable real-time analysis. Integration into ERP systems ensures seamless data transfer and automatic stock reconciliation.
How are inventory variances handled?
Discrepancies between book and actual balances are first verified by recounts. Confirmed differences lead to booking corrections and root cause analyses. Systematic deviations indicate weak points in warehouse processes and require process optimization to sustainably improve inventory accuracy.
