Inventory shortages can interrupt sales, affect customer satisfaction, and create unnecessary delays in fulfillment. When products aren’t available, buyers often see terms like “backorder” or “out of stock” without knowing the difference. Each situation impacts supply chain strategy and customer expectations in different ways. Knowing how they function gives businesses better control and keeps orders moving smoothly.
Definitions: Backorder vs Out of Stock
Both terms refer to unavailable inventory but affect operations and customer experience in different ways. Clear definitions help businesses maintain control during supply interruptions.
What is a Backorder?
A backorder occurs when a product is temporarily unavailable but will be restocked. Customers can still place an order and receive the item later. Backorders often reflect strong demand or supplier delays. This option allows continued sales despite gaps in inventory. Timely updates and accurate shipping estimates help maintain trust. Businesses often rely on strong supplier relationships to fulfill backorders quickly.
What does Out of Stock Mean?
Out of stock means the product is unavailable and cannot be purchased at the moment. No transactions happen until inventory is replenished. This often signals longer delays, supply disruptions, or discontinued items. It leaves buyers uncertain and more likely to seek alternatives. Communication around availability can reduce lost sales. Extended out-of-stock periods may damage brand reputation and customer loyalty.
Key Differences Between Backorder and Out of Stock
Backorders and out-of-stock situations both involve unavailable products, but they lead to very different outcomes for sales, fulfillment, and customer experience. Responding correctly depends on knowing what each one means and how it affects business operations.
| Backorder | Out of Stock |
| Items can still be purchased. | Items cannot be purchased. |
| Fulfillment delayed but expected. | No clear restock date. |
| Supports continued revenue. | Halts sales entirely. |
| Signals a temporary shortage. | May signal longer or unclear delay. |
| Requires communication of lead times. | Often requires updates or alternatives. |
Clarity between the two allows teams to adjust communication, plan inventory more accurately, and maintain buyer trust even when products aren’t immediately available. Identifying the difference early also supports better decision-making across operations and customer service.
Common Causes
Inventory issues interrupt sales and create challenges for customer service. Some problems start at the supplier level. Others are tied to internal systems, planning, or storage. Backorders and out-of-stock situations may look similar, but the reasons behind them often come from different points in the supply chain.
Causes of Backorders
- Demand exceeds available inventory, especially during peak seasons
- Delays in manufacturing or shipping impact availability
- Production holds due to raw material shortages
- Seasonal increases without proper forecasting or inventory buffers
- Slow turnaround between restocking and fulfillment creates a backlog
Causes of Out of Stock
- Inventory counts don’t match actual stock due to system errors
- Supplier cancellations or incomplete shipments leave orders unfulfilled
- Products removed from the catalog but still listed on ordering platforms
- Disorganized storage or picking errors cause stock to be misplaced
- No safety stock for high-volume items creates availability gaps
Pros & Cons of Backorders
Backorders help businesses keep sales active during short supply gaps, but they also come with risks. Managing them well requires accurate forecasting, strong supplier coordination, and clear customer communication. Some companies benefit from the flexibility, while others may face service issues if delays stretch too long.
Pros
- Keeps revenue flowing even when stock is low
- Allows customers to reserve high-demand items
- Helps test interest in new or limited products
- Reduces the need to cancel orders due to timing
- Supports lean inventory models without missing sales
Cons
- Can lead to long wait times and buyer frustration
- Requires additional communication and support
- May increase pressure on warehouse and fulfillment teams
- Higher risk of cancellations if delays are extended
- Negative impact on brand reputation if not handled carefully
Prevention Tips for Businesses
