How to Minimize Inventory Overstock and Understock

Knowing how much of a product you need to have stocked might seem like a skill that only the most successful companies know intuitively, but it’s a skill you can learn. As you figure out how to prevent inventory understocks and overstocks, you should follow a few guidelines and employ technology to fine-tune your inventory management process.

What Do Understocking and Overstocking Mean?

What are the definitions of overstocking and understocking? In the inventory management world, overstocking goes by a few different names, such as excess stock, excess inventory and stock surplus. Regardless of the terminology you employ, overstocking refers to a company over-ordering inventory and having too much stock. In contrast, understocking is when a company does not have enough inventory to keep up with the demand.

Causes of Overstocking and Understocking

1. Inaccurate Data

One of the primary reasons for under- or overstocking is a lack of solid data. Stolen goods, returns, shipment variances, and misplaced items all affect the needs of your inventory. Without accurate data, a company can believe that they have more or fewer items in stock than they actually have. Accurate data can help you discover trends with your sales.

2. Mismanagement of Technology, Staff, and Processes

Even with great data helping keep your shelves stocked, you’ll need staff who can properly sell the products. If key employees are unaware of the significance of the data, they can’t use it to improve the company’s inventory. Ensuring that staff members know how to use inventory management software programs is key.

3. Lack of Funds

Sometimes, understocking results from a business not having enough money to keep their inventory fully stocked. Finding ways to free up capital is crucial, as your ability to generate profit will be hindered by the amount of money you have to buy inventory.

4. Not Giving Time for Reorders to Arrive in Time

When you don’t reorder products in time, you’re going to run into understocking issues. Proactive attitudes towards reorders help ensure you maintain adequate stock levels.

5. Bad Supplier Communication

Poor communication between suppliers and buyers can lead to missed or delayed orders, potentially costing your company sales.

Danger of Understocking

When you understock, you open yourself to several negative effects. Understanding these can help in strategizing against understocking issues:

Problems and Consequences with Understocking

Missed sales: Having to turn away customers because you no longer have an item available.
Paying more for inventory: Buying in small batches typically costs more.
Loss of discounts: Bulk purchases often provide better pricing.
Shaken customer loyalty: Customers lose confidence in your ability to meet their needs.
Higher shipping costs: Constantly placing smaller orders increases shipping and processing costs.

Danger of Overstocking

Having too much inventory stocked can come with a variety of cost issues that may affect a company’s bottom line. Understanding these dangers is crucial in managing inventory effectively.

Problems and Consequences with Overstocking

Excessive Carrying and Opportunity Costs: Ties up funds in excess inventory.
Storage Costs: Increases in utilities, maintenance, and warehouse space.
Reduction in Demand for a Product and the Product’s Value: Prolonged storage can lead to damage and obsolescence.

How to Minimize Inventory Understocks and Overstocks

Many steps can be taken to enhance inventory management and maintain optimal stock levels:

1. Reduce Inventory That Is No Longer Relevant to the Market

Monitoring product life cycles helps prevent overstocking obsolete items.

2. Faster Supplier Lead Times

Choosing suppliers that can fulfill orders quickly can help manage stock levels effectively.

3. Centralize Data

Using an inventory management system that consolidates data from multiple sources can increase efficiency.

4. Build a Strong Relationship With Suppliers

Relationships with suppliers can ensure prioritized service and timely deliveries.

5. Automate Much of the Restocking Process

Using inventory management software can minimize human error and improve tracking.

6. Use an Inventory Management Software

This technology helps businesses contend with complexities of inventory effectively, reducing the likelihood of understocking and overstocking.
