Inventory Control Methods for Accurate Stock Management

In the late 1990s, the world saw a massive craze around collectible stuffed toys named Beanie Babies. These adorable plush creatures, produced by Ty Warner Inc., became a sensation. People lined up outside stores, waiting for the latest releases, convinced that their collections would one day fund their retirements. However, as demand skyrocketed, many retailers failed to predict the eventual decline and overstocked. The result? Boxes of unsold Beanie Babies piled high in warehouses and back rooms. The Beanie Babies bubble eventually burst, leaving behind a valuable lesson on the importance of accurate inventory control.

Inventory control is not just about ensuring you don't run out of products. It's also about not investing too much in stock that may become obsolete or may not sell. Effective stock management prevents stockouts, reduces storage costs, and avoids tying up capital in unnecessary inventory.

Below, we discuss some effective inventory control methods that ensure accurate stock management:

1. The Economic Order Quantity Model

Economic Order Quantity is a formula that determines the optimal order quantity which minimizes the total cost of ordering and holding inventory.

By using the EOQ model, businesses can calculate the ideal number of items to order. This helps in reducing costs associated with frequent small orders or large, infrequent ones.

2. Just-In-Time (JIT) Inventory?

Originating from Toyota’s production system, JIT aims at reducing inventory levels by ordering stock just when they are needed for production or sales.

JIT minimizes storage costs since you only keep stock that’s necessary for immediate production or sales. However, it requires robust relationships with reliable suppliers.

3. ABC Analysis

This method involves classifying inventory into three categories:

A: High-value items with low sales frequency

B: Moderate-value items with moderate sales frequency

C: Low-value items with high sales frequency

By understanding which items fall into which category, businesses can allocate resources effectively. High-value items (A) may need closer monitoring while low-value but high-turnover items (C) might be ordered in bulk.

4. Cycle Counting

Instead of conducting a full inventory count, cycle counting involves regularly counting a subset of inventory items.

This method ensures ongoing accuracy of inventory records, identifies issues early on, and avoids the disruption of a full-scale inventory count.

5. Dropshipping

A retail fulfillment method where a store doesn't keep the products it sells in stock. Instead, when a product is sold, the item is purchased from a third party and shipped directly to the customer.

Businesses don’t need to invest in inventory upfront, which reduces the risk of holding obsolete stock. It is particularly beneficial for startups and businesses with limited capital.

6. Consignment Inventory

A strategy wherein a supplier provides a product to a company, but the supplier retains ownership until the product is sold.

This reduces the risk for businesses as they aren't buying the product upfront. It is ideal for products that are unproven in the market or for businesses testing new inventory.

7. FIFO (First In, First Out) and LIFO (Last In, First Out)

FIFO means the oldest inventory items are sold first. LIFO means the newest inventory items are sold first.

FIFO is particularly effective for perishable goods, ensuring old stock gets sold before it expires. LIFO can be beneficial for tax purposes, especially during periods of rising prices.

While the Beanie Babies serves as a cautionary tale, the lessons from their overstocking are evident. Accurate inventory control is more than just counting items. It is about managing resources, predicting demand, and ensuring that businesses can meet their customers' needs without overburdening their storage or finances.

By employing one or a combination of the inventory control methods mentioned above, businesses can optimize their stock management, ensure smoother operations, and safeguard against costly inventory mistakes. After all, in the business world, it's not just about having products to sell, but having the right amount of them at the right time.
