Inventory refers to the quantity of goods physically present in a warehouse or managed in a system at a given point in time. It forms the basis for delivery capability, materials planning, and inventory management.
Key facts
- Inventory refers to the total of all goods physically present or system-managed within a company at a given point in time.
- Stock is divided into status types such as available, reserved, blocked, and in transit in order to accurately reflect actual availability.
- Discrepancies between book inventory and physical inventory lead to planning errors and must be corrected through regular stocktakes.
- The optimal stock level is a trade-off between delivery capability and capital commitment – there is no universal formula.
- Safety stock and reorder point are defined sub-quantities within the total inventory and serve to provide protection against supply fluctuations.
What is inventory?
Inventory encompasses all goods that are accessible to a company at a defined point in time – whether physically stored, in processing, or in transit. In modern warehouse management systems (WMS) and ERP systems, inventory is not maintained as a single uniform figure but is divided into different stock types: available stock is ready for immediate allocation, reserved stock has already been assigned to an order, blocked stock is subject to a quality inspection or hold, and transit stock is in transit between two warehouse locations or suppliers.
How does inventory management work in practice?
In day-to-day operations, inventory is updated in real time with every goods movement – putaway, goods issue, transfer, or picking. The accuracy of these postings is critical: discrepancies between book inventory and physical inventory lead to delivery problems, planning errors, and unnecessary reorders. Regular stocktakes as well as perpetual inventory procedures are used to detect and correct such discrepancies at an early stage.
For planning purposes, several key figures are relevant in addition to the current stock level:
- Minimum stock: the lower threshold below which a replenishment order is triggered.
- Safety stock: a defined buffer that absorbs delivery delays and demand fluctuations.
- Reorder point: the stock level at which a procurement process is initiated.
These figures are set individually depending on the article, lead time, and sales behavior, and are reviewed on a regular basis.
What matters when managing inventory?
A central challenge is striking the right balance between delivery capability and capital commitment. High stock levels ensure supply continuity but place a burden on liquidity and storage space. Excessively low stock levels put delivery performance at risk. The right inventory strategy depends on factors such as item value, turnover frequency, forecast accuracy, and supplier structure – no blanket recommendation can be made here.
Modern approaches such as Vendor Managed Inventory (VMI) shift part of the inventory responsibility to the supplier. Replenishment software and AI-driven forecasting models can help adjust stock levels dynamically. Whether such systems are suitable in a given environment, however, depends on the vendor and the processes involved and should be evaluated on a case-by-case basis.
