What Is Inventory?

Inventory refers to the goods, materials, and products that a business holds for the purpose of production, sale, or distribution. This includes raw materials, work-in-progress (WIP), finished goods, spare parts, and consumables stored across warehouses, stores, or distribution centers.

In supply chain and warehouse operations, inventory represents both a critical asset and a cost requiring accurate tracking, control, and optimization to meet demand without overstocking or shortages.

Purpose

The primary purpose of inventory is to:

  • Ensure uninterrupted production and order fulfillment

  • Meet customer demand on time

  • Balance supply and demand efficiently

  • Reduce stockouts and excess holding costs

  • Support business continuity and scalability

Regulation

Inventory management is governed by a combination of accounting standards, tax regulations, and industry practices.

  • Accounting: Inventory valuation follows standards such as IFRS (IAS 2) or GAAP

  • Taxation: Inventory impacts GST/VAT, customs valuation, and income tax reporting

  • Compliance: Certain goods may be subject to regulatory controls, batch tracking, or expiry monitoring

Internationally, inventory practices align with global accounting and supply chain standards, while local laws define reporting and audit requirements.
