Striking the perfect balance between supply and demand is a complex dance for any business. If you don’t have enough inventory on hand you risk selling out. Too much, and you’ll be stuck with an inventory glut.

An inventory glut occurs when a company has surplus inventory and the stock of products far exceeds its demand.

The result?

Financially, it can lead to significant losses as businesses are forced to sell stock at discounted prices, or worse, write off unsold inventory as a loss. Operationally, excess inventory can clog warehouses, making it challenging to manage new stock efficiently. To top it all off, it poses a serious challenge for sustainable practices, as unsold products contribute to waste and environmental concerns.

In this guide, we’ll explore the main causes of inventory glut, innovative strategies to tackle it, and how working with a 3PL can help reduce inventory risk.

What is inventory glut?

Inventory glut happens when a business is holding more inventory than it can sell in a reasonable time frame. Its cause can be related to poor demand forecasting, changes in global economic conditions, supply chain disruptions, or shifts in consumer preferences.

Inventory glut affects businesses both large and small. In fact, according to a report, two-thirds of retailers had excess inventory during the 2023 holiday season last year. This includes major brands like Foot Locker and Ulta.

The thing is, inventory glut affects sectors differently:

  • Ecommerce businesses: An inventory glut often results in heavy discounts and promotional sales, impacting profit margins.
  • General retailers: Unsold inventory not only takes up valuable space but also ties up capital that could be used for other operational needs.
  • Supply chains: Excess inventory or stock in warehouses can disrupt the flow of goods, and logistics companies may struggle with storage issues, further complicating supply chain management.

Regardless of the sector, inventory glut is never a good problem to have. To properly manage it, businesses need to be proactive in implementing the right strategies and technologies. 

What causes inventory glut?

Various factors can contribute to inventory glut. Some, like overproduction and seasonal fluctuations, are within a business’s ability to mitigate with the proper systems. Others, like supply chain disruptions and consumer spending changes, are caused by external factors and not within a business’s direct control.

That being said, let’s further explore the reasons that cause businesses to overstock.


One of the primary reasons for inventory glut is when companies manufacture or purchase more goods than the market demands. This is often due to inaccurate demand forecasting, ordering too much buffer inventory to avoid shortages, or purchasing well above the minimum order quantity to capitalise on economies of scale.

Seasonal fluctuations

Seasonal businesses often struggle with inventory glut, where demand for certain products is high during specific times of the year. But, excessive stockpiling outside these periods can result in a surplus.

Supply chain disruptions

Black swan events like a global pandemic can create a bullwhip effect on your supply chain and contribute to inventory glut. For instance, during the onset of the COVID-19 pandemic, consumer demand for certain products, such as hand sanitizers and toilet paper, surged unexpectedly

While many retailers were initially dealing with the pain of stockout costs, they rapidly increased production. However, the next year as panic buying subsided and regular supply chains resumed, demand dropped significantly — resulting in the bullwhip effect.

Economic conditions and consumer spending patterns

Changes in economic conditions and consumer spending patterns can decrease a business’s sell-through rate. For example, an early 2023 report found that nearly 70% of consumers planned on cutting back on nonessential spending. Additionally, inflation reaching a 40-year high level has affected consumers’ ability to afford many products.

Just take the following chart showing a significant rise in year-over-year inventory levels for these major retailers (including Walmart, Target, and other retail giants). As consumers shifted their spending habits, it left many in the retail industry with excess inventory. 


Analising the financial implications of excess inventory

As of October 2023, US retailers combined are holding over $795 billion worth of inventory. 


Although not all of this is considered inventory glut, it’s safe to assume that at least some of this inventory figure is related to overstocking.

The problem is, inventory glut has far-reaching economic consequences for businesses, impacting their financial health in multiple ways. Understanding these impacts is crucial for effective inventory management and maintaining a healthy bottom line.

Capital tie-up

Excess inventory ties up capital that could otherwise be used for business development, marketing, or other operational areas. This reduction in liquidity limits a company’s flexibility and ability to respond to market changes.

Additionally, the capital invested in excess inventory represents an opportunity cost, as it is not being used for potentially profitable investments or improvements in other areas of the business.

Storage costs

Storing excess inventory leads to higher holding costs. This includes rent for warehouse space, utilities, insurance, and security.

Moreover, storing certain products for excessively long periods may result in obsolete inventory. Therefore, unaware business owners could be paying storage fees on inventory they may not even be able to use anymore.

Markdowns and discounts

To clear excess inventory, businesses often resort to markdowns and discounts. While this strategy can help move stock, it significantly erodes profit margins. Just take a look at the example below. If you have a 30% margin, and you give a 5% discount, you have to sell 20% more units to make the same profits.


Additionally, frequent discounts can negatively affect a brand’s perception, leading customers to expect lower prices and wait for sales rather than purchasing at full price.

6 innovative strategies to tackle inventory glut

In the face of inventory glut, businesses are increasingly seeking innovative solutions that go beyond traditional markdowns. These strategies not only help in managing excess stock but also provide a cost-effective and sustainable approach to improving their inventory turnover ratio

1. Inventory redistribution

One effective strategy is to redistribute inventory to locations where it’s more likely to sell. By analising inventory analytics across different regions or stores, businesses can identify areas with higher demand for certain products. This approach reduces inventory days on hand thus, optimising stock levels.

ShipBob’s advanced analytics and distributed inventory solutions enable businesses to strategically move products to fulfilment centres closer to high-demand areas, reducing shipping times and costs.

2. Dynamic pricing strategies

Dynamic pricing involves adjusting the prices of products based on real-time market demand, competitor pricing, and other factors. This option may not apply to all ecommerce businesses but if you’re selling on Amazon, then utilising their dynamic price rules or customising your own is certainly an option.

3. Donations and recycling programs

Donating or recycling unsold products is a sustainable approach to managing inventory glut. This helps in clearing stock and contributes to corporate social responsibility efforts. For example, Designer Brands donated five million pairs of shoes to Soles4Souls, a global nonprofit.

These types of initiatives can enhance a company’s brand image and customer loyalty. Plus, donations can often be written off, providing a financial benefit.

4. Collaborative promotions and partnerships

Collaborating with other brands for joint promotions can help move excess inventory. This can include bundled offers or cross-selling with complementary products from partner brands.

These partnerships can open up new customer segments and markets, providing a fresh avenue to offload surplus stock.

5. Implementing flash sales and pop-up events

Organising flash sales or pop-up events can create a sense of urgency and exclusivity, encouraging customers to purchase. These events can be particularly effective in clearing inventory quickly.

With ShipBob’s agile fulfilment services, businesses can rapidly deploy products for these events, ensuring timely delivery and customer satisfaction.

6. Subscription boxes and mystery packages

Offering surplus inventory as part of subscription boxes or mystery packages can be an appealing way for customers to receive value while helping businesses clear stock.

This strategy not only addresses inventory glut but also boosts customer engagement, as customers enjoy the surprise element.
