What Is Inventory Management?

Inventory management refers to overseeing the flow of goods from manufacturers to warehouses and ultimately to customers. This includes raw materials, work-in-progress items, and finished products. Effective inventory management ensures that businesses have the right products, in the right quantities, at the right time.

Types of Inventory Management Techniques

Just-in-Time (JIT)

A strategy where inventory is replenished exactly when needed, reducing storage costs. JIT lowers the cost of holding inventory, reduces waste and improves cash flow. Despite these benefits, the biggest drawback is that it requires reliable suppliers. It is also vulnerable to supply chain disruptions.

First-In, First-Out (FIFO)

For FIFO, the oldest inventory items are sold first. It is suitable for perishable items or products with expiry dates.

Economic Order Quantity

The economic order quantity (EOQ) calculates the ideal order quantity to minimize total inventory costs. It has the formula:

EOQ = √ [2DS/H]

D = Demand in units (annual)
S = Order cost
H = Holding costs (per unit, per year)

Demand in units is derived from historical demand data.

Holding cost is calculated by adding all the costs associated with storing your inventory and then dividing that total by the total value of your inventory.

Order cost includes all expenses incurred in purchasing and receiving inventory items.

Perpetual Inventory System

This system utilizes real-time tracking software to monitor inventory levels, meaning inventory is automatically updated after each transaction. Unlike periodic inventory systems, which depend on manual stock counts at set intervals, the perpetual system uses technology to maintain continuous records of stock changes resulting from sales, purchases, or returns. A point-of-sale (POS) system or barcode scanner records each activity.

Batch Tracking

Batch tracking is an inventory management technique that monitors and records the movement of goods based on specific batches or lots. A batch is a group of items produced or purchased together, sharing the same production date, expiration date, or other identifying details.
