A warehouse system shows 500 units of a fast-moving product in stock, but a physical count finds only 470. So, where did those 30 units go? They may have been damaged, misplaced, recorded incorrectly, received in the wrong quantity, or even stolen. Whatever the reason, the business is left with less stock than its records show.
This difference is called inventory shrinkage. It may look like a simple stock-counting issue, but repeated discrepancies can affect purchasing, replenishment, order fulfilment, and overall profitability. The National Retail Federation (NRF) also points out that shrink can come from several sources, including theft, administrative errors, damaged or expired goods, and other inventory losses.
In this guide, we will look at what inventory shrinkage means, what causes it, how it affects warehouse operations, and what businesses can do to prevent and identify it more effectively.
What Is Inventory Shrinkage?
Inventory shrinkage is the difference between the inventory recorded in a business’s system and the inventory that is physically available.
For example, if the system records 10,000 units but a physical count finds 9,850, there is a discrepancy of 150 units. The next step is to determine why those units are missing from the physical stock.
Shrinkage can occur at several points in the inventory lifecycle, including receiving, storage, picking, movement between locations, returns, and dispatch. Some losses involve physical stock, while others result from incorrect records or processes.
This is why shrinkage should not automatically be treated as theft. NRF’s 2025 guidance highlights that shrink can include administrative errors, damage, expired goods, vendor fraud, employee theft, and external theft.
How Is Inventory Shrinkage Calculated?
Businesses can calculate inventory shrinkage by comparing the value recorded in the inventory system with the value of stock physically available.
Shrinkage Value = Recorded Inventory Value − Actual Inventory Value
Shrinkage Rate = (Shrinkage Value ÷ Recorded Inventory Value) × 100
For example, if a warehouse records $200,000 in inventory but the physical count shows $194,000, the shrinkage is $6,000, resulting in a shrinkage rate of 3%.
Tracking the rate over time can help identify whether inventory discrepancies are increasing or decreasing. However, the figure needs to be viewed in context because organisations may use different methods to calculate and report shrinkage.
What Causes Inventory Shrinkage?
Inventory shrinkage can happen at different points in the inventory process. Below are some of the possible reasons:
- Receiving errors: The quantity received may differ from the quantity recorded in the inventory system.
- Picking and dispatch errors: Items may be picked incorrectly, moved to the wrong location, or shipped without updating the inventory record.
- Administrative mistakes: Data-entry errors, duplicate records, incorrect labelling, or unauthorised manual adjustments can create inventory discrepancies.
- Damage and expiry: Damaged, spoiled, or expired products may become unsellable but remain listed as available inventory.
- Employee or external theft: Inventory may be removed without proper authorisation or recorded movement.
- Supplier discrepancies: Short shipments or differences between expected and received quantities can lead to stock mismatches.
- Poor movement tracking: When inventory moves between locations without being scanned or recorded, the system may continue showing an incorrect stock position.
The cause is not always immediately obvious. Looking at where and when the discrepancy occurred can help warehouse teams identify the underlying issue and take the right corrective action.
How Does Inventory Shrinkage Affect a Business?
A stock discrepancy can create problems across daily warehouse operations, inventory planning, customer fulfilment, and financial reporting. Some of the possible impacts include:
- Lost inventory directly reduces the value of stock available for sale.
- Incorrect stock records can lead to unnecessary purchases or unexpected stockouts.
- Teams may spend additional time performing recounts and investigating discrepancies.
- Fulfilment operations can be disrupted when the system shows stock that is not physically available.
- Repeated discrepancies can make demand forecasting and replenishment less reliable.
- Unrecorded inventory losses can affect financial reporting and profitability.
NRF’s recent work also points to a broader shift in how retailers view loss. Its 2026 discussion on total retail loss looks beyond traditional shrink to include inventory inaccuracies, supply chain issues, fraud, and other operational losses that affect profitability.
How Can Inventory Shrinkage Be Prevented?
Preventing inventory shrinkage starts with improving accuracy at the points where stock is received, stored, moved, picked, counted, and dispatched. The following practices can help reduce discrepancies and make them easier to identify:
- Conduct regular cycle counts, with greater attention to high-value and fast-moving SKUs.
- Verify quantities during receiving instead of relying only on supplier documentation.
- Use barcode or RFID scanning to record inventory movements accurately.
- Require scan confirmation during picking and dispatch.
- Restrict manual inventory adjustments to authorised users.
- Investigate recurring discrepancies instead of simply correcting the stock figure.
- Review damaged, expired, returned, and rejected goods separately.
- Use access controls and monitoring to reduce unauthorised inventory movement.
- Connect inventory tracking with the warehouse management system so movements are reflected in the system promptly.
The objective is not simply to discover shrinkage during the next physical audit. It is to identify discrepancies closer to the point where they occur, while the cause is still easier to trace.
Why Real-Time Inventory Tracking Matters
Manual processes can work for smaller operations, but they become harder to control as the number of SKUs, locations, employees, and daily movements increases.
Barcode and RFID technology can add an additional layer of accuracy by identifying inventory as it moves through receiving, storage, picking, and dispatch. When connected to a Warehouse Management System, these scans can also create a more consistent record of where inventory is and how it has moved.
This is particularly useful when an organisation needs to identify where a discrepancy occurred, rather than simply discovering that the final stock count is wrong.
For example, if the system records a product as received but there is no corresponding movement into storage, the receiving process can be reviewed immediately. Similarly, a mismatch during picking can be investigated before the shipment leaves the facility.
How DCSME Supports Inventory Visibility
DCSME approaches inventory visibility through a combination of warehouse management, asset and inventory tracking, barcode, RFID, and related data-capture technologies rather than relying on manual stock records alone.
Its solutions can support inventory processes by connecting scanning and identification technologies with warehouse workflows, helping organisations track products as they move through different stages of the operation. This approach is particularly relevant for warehouses and distribution environments where inventory passes through multiple locations or handling points.
DCSME works across the UAE, Kuwait, Bahrain, Oman, Qatar, and KSA, supporting organisations with warehouse technology and connected operational systems. For a business experiencing recurring inventory discrepancies, the starting point should be identifying where those discrepancies occur and then selecting the right combination of process controls and tracking technology.
Conclusion
Inventory shrinkage is ultimately a visibility and control problem. The difference between system stock and physical stock may result from theft, but it can also result from receiving errors, damaged goods, incorrect records, supplier discrepancies, or inventory movements that were not properly recorded.
A practical prevention strategy therefore starts with accurate processes, regular cycle counting, clear accountability, and reliable inventory tracking. As warehouse operations become larger and more distributed, barcode, RFID, and WMS technology can help teams move from discovering discrepancies after the fact to identifying them much closer to where they occur.
For organisations looking to improve inventory accuracy across their warehouse or retail operations, DCSME can assess existing inventory flows and identify where tracking, scanning, and warehouse management technologies can provide greater visibility.
Frequently Asked Questions
What is inventory shrinkage?
Inventory shrinkage is the difference between the quantity or value of inventory recorded in a system and the stock physically available.
Is inventory shrinkage always caused by theft?
No. Shrinkage can also result from receiving errors, administrative mistakes, damaged or expired goods, supplier discrepancies, and incorrect inventory records.
How can a warehouse reduce inventory shrinkage?
Regular cycle counts, accurate receiving and picking processes, restricted manual adjustments, employee training, and barcode- or RFID-based inventory tracking can help reduce discrepancies.
How does RFID help prevent inventory shrinkage?
RFID can identify and track tagged inventory as it moves through receiving, storage, picking, and dispatch. When integrated with warehouse systems, it can improve visibility and help identify discrepancies earlier.
Can a Warehouse Management System reduce inventory shrinkage?
A WMS can improve inventory accuracy by recording and coordinating activities such as receiving, put-away, picking, transfers, and dispatch. It does not eliminate shrinkage on its own, but it can make inventory movements easier to track and investigate.
