  • General
  • 4 minute read

Businesses often use the terms surplus inventory and overstock inventory interchangeably. While closely related, they don’t always mean the same thing. Understanding the difference can help businesses make better decisions about managing and selling excess stock.

What Is Surplus Inventory?

Surplus inventory is stock that a business has more of than it currently needs or expects to sell through its regular sales channels.

Surplus inventory can happen because of:

  • Changes in customer demand
  • Cancelled orders
  • Seasonal products
  • Discontinued items
  • Customer returns
  • Excess purchasing
  • Unsold products

It is a broad term that covers different types of excess or unwanted inventory.

What Is Overstock Inventory?

Overstock inventory is stock that a business has purchased or produced in quantities greater than current demand.

For example, if a retailer expects to sell 1,000 products but has 1,500 units remaining, the additional 500 units may be considered overstock.

Overstock often results from inaccurate demand forecasting, large purchases, or slower-than-expected sales.
