Material Management, often used interchangeably with inventory management, covers the processes for procuring, receiving, storing, valuing and tracking the materials and goods an organisation needs. It spans raw materials, components, consumables and finished products, and aims to ensure the right items are available in the right quantity at the right place and time, while keeping tied-up capital and storage costs under control. In an ERP system it is a core module that connects procurement, warehousing, production and finance, maintaining stock figures and material master data on which material planning and valuation depend.

What Material Management (Inventory Management) is NOT — disambiguation
Not a warehouse management system: A WMS executes physical storage and movement, while material management is the broader control and valuation of stock.
Not material planning: Material planning decides future requirements, whereas material management records and values the stock that results.
Not procurement alone: Procurement obtains goods, while material management also covers storage, valuation and tracking after receipt.
Not asset accounting: It handles consumable and saleable stock, not the fixed assets tracked in fixed-asset accounting.

Scope of material management
Material management brings together several closely related activities. It records goods receipts and issues, tracks stock levels by location and storage bin, manages reservations and transfers, and values inventory for the financial accounts. It maintains the material master data that describes each item, including units of measure, classifications and valuation method. In practice it overlaps with procurement on the inbound side and with production and dispatch on the outbound side, acting as the system of record for what is physically present and what it is worth.

Inventory control methods
To balance availability against cost, material management uses established control techniques. Reorder-point logic triggers replenishment when stock falls to a defined level, while safety stock buffers against demand and supply variability. ABC analysis classifies items by value or importance so that effort is concentrated where it matters most. Valuation methods such as LIFO and average costing determine how stock movements affect the books. These techniques let an organisation decide how much to hold and when to reorder rather than reacting after a shortage.
Relationship to warehousing and planning
Material management is closely tied to, but distinct from, warehouse management and material planning. A warehouse management system focuses on the physical execution of storage and movement inside a facility, such as putaway and picking, whereas material management is the broader accounting and control of stock and its value. Material planning decides what to procure or produce to meet future demand, then hands the resulting movements back to material management to execute and record. To keep figures correct, organisations rely on disciplined posting and methods such as perpetual inventory alongside periodic counts.

Role in the ERP and in finance
Within an ERP system, material management is the bridge between physical operations and the financial ledger. Every goods movement can post a corresponding accounting entry, so inventory on the balance sheet reflects what is actually in stock. Accurate stock and valuation feed cost accounting, margin analysis and reporting, while reliable availability data supports order promising and production scheduling. Because so many functions read from the same stock and material data, the quality of that master data and the discipline of posting movements promptly are decisive for trustworthy figures across procurement, production, sales and finance.
MM (Material Management) is the ERP-integrated module covering procurement, inventory and basic warehouse functions. WMS (Warehouse Management System) is a specialist platform for warehouse execution — bin-level optimisation, wave-picking, slotting, labour management. Many DACH mid-market operations run MM only; larger operations supplement MM with dedicated WMS (Manhattan, JDA/Blue Yonder, SAP EWM).
Can we run multiple valuation methods simultaneously?
Yes. SAP S/4HANA supports parallel valuations (HGB-cost, IFRS-cost, group-cost) per material with separate posting flows. Microsoft Dynamics 365 F&O has similar capability through cost-versions. Most German GmbHs subject to IFRS group reporting maintain at least two parallel valuations.
How does material management interact with batch traceability?
MM master data carries the batch-tracking configuration per material. When configured, every inventory movement records the specific batch. The data structure supports batch traceability queries. For pharma and food, batch tracking is mandatory; for other industries, it's optional but increasingly common for quality-management and recall-readiness.
