Retail profitability can disappear in ways that are difficult to see. A product may be recorded in the inventory system but no longer be available on the shelf. A warehouse may receive fewer units than the quantity written on a supplier document. A cashier may process a refund incorrectly, an employee may apply an unauthorized discount, or a damaged item may be discarded without being recorded.
Individually, these incidents may appear insignificant. Across thousands of products, transactions, employees, and store locations, however, they can create a major financial problem.
This loss is commonly known as retail shrinkage.
Understanding shrinkage in retail causes is essential because shrinkage affects much more than inventory value. It can reduce gross margins, create misleading stock records, contribute to stockouts, distort demand forecasts, complicate financial reporting, and weaken customer confidence.
Shrinkage is also not caused exclusively by shoplifting. Theft may be highly visible, but operational errors, employee misconduct, supplier discrepancies, damaged products, inaccurate data, and weak inventory controls can be equally damaging. Retailers therefore need a broad strategy that addresses both criminal activity and everyday operational weaknesses.
What Is Retail Shrinkage?
Retail shrinkage is the difference between the inventory a retailer should have according to its records and the inventory that is physically available.
For example, a retailer’s system may indicate that a store has 100 units of a product. During a physical count, employees find only 94 units. The missing six units represent inventory shrinkage unless the retailer can identify another explanation, such as products that were sold but not recorded correctly.
Shrinkage is normally calculated using the following formula:
Shrinkage = Recorded inventory value − Actual inventory value
The shrinkage percentage can then be compared with total sales or the total value of available inventory.
Although the calculation appears straightforward, identifying the actual shrinkage in retail causes can be much more complicated. A missing item may have been stolen, damaged, incorrectly received, transferred to another store without documentation, sold under the wrong SKU, or removed from inventory without being properly written off.
The National Retail Federation reported an average retail shrink rate of 1.6% in its 2023 National Retail Security Survey, representing approximately $112.1 billion in losses based on 2022 retail sales. However, industry measurement remains challenging because retailers do not always classify shrinkage consistently, and the underlying cause of every missing item cannot always be determined.
For a business operating on a narrow profit margin, even a relatively small shrinkage percentage can eliminate a substantial part of its earnings.
Why Retailers Must Understand the Causes of Shrinkage
Retailers often focus on revenue growth, customer acquisition, merchandising, and store expansion. These areas are important, but increasing sales will not necessarily improve profitability when inventory continues to disappear.
Suppose a retailer earns a gross margin of 25% on a product. Replacing Rp10 million worth of missing inventory may require substantially more than Rp10 million in additional sales because only a portion of each sale becomes gross profit.
Shrinkage can also create secondary losses. When inventory records show that products are available even though shelves are empty, automated replenishment systems may not trigger new purchase orders. Customers may visit the store expecting an item to be available, only to discover that it is out of stock.
Managers may then make purchasing, pricing, promotion, and allocation decisions using inaccurate information.
Research involving approximately 24,000 SKUs across 11 grocery stores found that inventory record inaccuracies were associated with factors such as higher inventory levels, frequent replenishment, and product perishability. The same study found that inventory audits produced an 11% store-wide sales lift, concentrated on products where system inventory was higher than actual inventory.
This illustrates why examining shrinkage in retail causes is not simply an accounting exercise. Accurate inventory can directly affect product availability and sales performance.
1. Customer Shoplifting
Customer shoplifting is one of the most recognized shrinkage in retail causes. It includes products being concealed in bags or clothing, packaging being opened, labels being switched, barcodes being replaced, and items being intentionally left unscanned at self-checkout.
Some incidents are opportunistic, while others involve organized groups that steal specific merchandise for resale. High-value, portable, and easily resold products are often attractive targets. These may include cosmetics, electronics, branded clothing, personal care products, medicines, food, and household essentials.
Recent retail crime reports indicate that theft has become increasingly sophisticated and may involve coordinated networks, fraudulent returns, online resale channels, cargo diversion, and repeated targeting of multiple stores. The NRF’s 2025 report described retail crime as an increasingly complex concern affecting retailers, employees, customers, and communities.
However, focusing only on shoplifting can cause retailers to overlook other forms of shrinkage. Security guards, cameras, locked cabinets, electronic article surveillance, and receipt checks may help deter theft, but they cannot correct inaccurate receiving, improper refunds, or internal fraud.
Excessively restrictive security measures can also harm the customer experience. Locked display cases may discourage legitimate purchases because customers must wait for assistance. Retailers therefore need controls that reduce theft without making the store uncomfortable or inconvenient.
2. Employee Theft and Internal Fraud
Employees often have more access to products, cash registers, stockrooms, systems, and company procedures than customers do. This makes internal theft one of the most serious shrinkage in retail causes.
Employee-related shrinkage may involve directly taking merchandise, processing fake refunds, canceling completed transactions, abusing employee discounts, issuing unauthorized markdowns, giving products to friends, manipulating loyalty points, or collaborating with external shoplifters.
Internal fraud can remain undetected for long periods because the person involved may understand the company’s controls and know how to avoid attention. A cashier might process a transaction correctly on the surface while intentionally failing to scan certain items. A warehouse employee may remove products before they reach the sales floor. A supervisor may approve suspicious refunds because approval rules are weak.
Reducing internal theft requires more than employee surveillance. Retailers need separation of duties, role-based system access, transaction approval thresholds, exception reports, regular audits, and a clear record of who performed each activity.
For example, the same employee should not be able to create a supplier, approve a purchase, confirm receipt, and authorize payment without independent review. Similarly, refunds above a defined value should require managerial approval and remain visible in an audit trail.
A positive workplace culture is also important. Fair policies, appropriate staffing, effective management, confidential reporting channels, and consistent disciplinary procedures can help reduce the conditions that allow misconduct to develop.
3. Administrative and Data Entry Errors
Many retailers still rely on manual data entry, spreadsheets, disconnected applications, or paper-based inventory processes. These methods increase the possibility of mistakes.
An employee may enter 100 units instead of 10, select the wrong SKU, record an incorrect unit of measure, duplicate a purchase receipt, or process a transfer to the wrong location. A product may be sold under a similar barcode, causing one item’s stock to decrease while another item remains overstated.
These administrative mistakes are important shrinkage in retail causes because they create inventory losses on paper even when no physical theft has occurred.
Data errors can happen at almost every stage of retail operations:
- Product setup
- Purchase ordering
- Goods receiving
- Warehouse put-away
- Store replenishment
- Point-of-sale transactions
- Interstore transfers
- Returns and refunds
- Stock adjustments
- Physical inventory counts
When systems are disconnected, the same transaction may need to be entered several times. A sale recorded in the point-of-sale platform may not immediately update the inventory or accounting system. Employees may then make manual adjustments, creating additional opportunities for errors.
The risk becomes greater as retailers add more stores, warehouses, ecommerce channels, marketplaces, and delivery partners.
4. Receiving and Supplier Discrepancies
Shrinkage may begin before merchandise reaches the sales floor. A supplier may ship fewer items than the quantity listed on the invoice, send incorrect products, substitute lower-value goods, or deliver damaged merchandise.
If employees approve deliveries without carefully counting and inspecting the products, the retailer may pay for inventory it never received.
Supplier-related shrinkage in retail causes may be intentional or accidental. A supplier could make a packing error, while a carrier could lose or damage products during transportation. In more serious cases, a vendor, driver, or employee may deliberately manipulate quantities or documentation.
Retailers can reduce receiving discrepancies by comparing purchase orders, delivery documents, physical quantities, and supplier invoices. This process is often called three-way matching.
Barcode scanning can also improve receiving accuracy. Instead of entering quantities manually, employees can scan each carton or item and immediately identify unexpected products, duplicate deliveries, or shortages.
Any discrepancy should be documented before the delivery is accepted. Photographs, timestamps, employee identification, and supplier communication can provide useful evidence when requesting a replacement or credit.
5. Product Damage and Spoilage
Not every missing product has been stolen. Merchandise can become damaged during transportation, unloading, storage, shelf replenishment, customer handling, or daily store operations.
Food, beverages, cosmetics, medicines, and other perishable goods may expire before they are sold. Temperature-sensitive products may become unusable when refrigeration fails. Clothing can be stained or torn, glass containers can break, and electronic products may be damaged by moisture or improper storage.
Damage and spoilage become shrinkage in retail causes when employees dispose of products without properly recording the loss. The physical inventory decreases, but the system continues to show the product as available.
Retailers need standardized procedures for identifying, documenting, approving, and writing off damaged inventory. The system should capture the product, quantity, location, reason, date, and responsible employee.
This information helps management distinguish between normal waste and preventable losses. If one store repeatedly reports damaged beverages, the cause may be poor handling, unsuitable shelving, incorrect storage, or a supplier packaging problem.
Without detailed reason codes, all these losses may simply be classified as unexplained shrinkage.
6. Pricing, Promotion, and Markdown Errors
Retail pricing has become increasingly complex. Prices may vary across physical stores, ecommerce websites, marketplaces, loyalty programs, customer segments, and promotional periods.
When pricing data is not synchronized, employees may apply incorrect discounts or manually override the point-of-sale system. A promotion may continue after its scheduled end date, or two discounts may be combined even though the retailer intended customers to receive only one.
Incorrect pricing does not always remove physical inventory, but it can reduce the expected value received from that inventory. For this reason, pricing and markdown errors are often included among operational shrinkage in retail causes.
Retailers should centralize price rules and define who can create, approve, modify, and activate promotions. The system should also identify unusual activities, such as repeated price overrides, excessive markdowns, or discounts applied outside authorized periods.
The objective is not to prevent employees from helping customers. It is to ensure that exceptions are transparent and consistently managed.
7. Return and Refund Fraud
Retail return policies are designed to provide customers with confidence. Unfortunately, weak return controls can also create opportunities for fraud.
A person may return stolen merchandise, present counterfeit receipts, return a different item inside the original packaging, claim that an item was never delivered, or repeatedly purchase and return products after using them.
Employees may also create false returns and keep the refunded cash or credit.
Return fraud is one of the more complicated shrinkage in retail causes because retailers must balance fraud prevention with customer convenience. Policies that are too restrictive may discourage legitimate buyers, while policies that are too flexible may invite abuse.
A connected transaction history can help retailers verify purchases, payment methods, product serial numbers, customer return patterns, and previous refunds. High-risk transactions can then be reviewed without delaying every customer.
Refunds should generally be returned through the original payment method. Cash refunds, receipt-free returns, and manual adjustments may require additional approval, especially for high-value merchandise.
8. Self-Checkout Errors and Abuse
Self-checkout technology can reduce queues and provide customers with more flexibility, but it introduces additional shrinkage risks.
Customers may unintentionally scan the wrong barcode, enter an incorrect quantity, place an item in the bagging area without scanning it, or select a cheaper product from a menu. Others may deliberately exploit the system.
Theft at self-checkout is not always sophisticated. A customer may simply fail to scan one product in a large basket. When repeated across thousands of transactions, these incidents can produce significant losses.
Retailers should analyze self-checkout transactions alongside video, weight sensors, employee interventions, voids, and unusual scanning behavior. Attendants must also be trained to assist customers and recognize suspicious activity without creating unnecessary confrontation.
Technology should support employees rather than completely replace human supervision.
9. Inaccurate Inventory Transfers
Retailers with multiple stores and warehouses frequently move merchandise between locations. Every transfer creates another point where inventory can become inaccurate.
One location may ship 20 units while the receiving store records only 18. Goods may be sent to the wrong branch, remain in transit for too long, or arrive without confirmation. Employees may also move inventory informally without creating a transfer transaction.
These situations are common shrinkage in retail causes for growing retailers because the inventory technically still exists, but the company cannot determine exactly where it is.
Transfer processes should record the sending location, receiving location, shipment date, expected quantity, actual quantity, carrier, tracking information, and responsible employees. The system should also highlight transfers that have remained open beyond the expected delivery period.
Using barcode or RFID scanning at both dispatch and receipt creates a clearer chain of custody.
10. Weak Inventory Management and Limited Visibility
Many individual shrinkage problems are symptoms of a broader issue: insufficient inventory visibility.
When stock data is spread across separate point-of-sale, warehouse, ecommerce, purchasing, and accounting systems, managers cannot easily compare transactions or investigate discrepancies.
Reports may arrive days or weeks after the loss occurred. By that point, security footage may be unavailable, employees may not remember the transaction, and products may have moved through several locations.
Poor stock management is therefore both a cause of shrinkage and an obstacle to identifying other shrinkage in retail causes.
Retailers need timely information about inventory on hand, committed stock, products in transit, damaged goods, returns, adjustments, purchase receipts, and sales. They also need visibility across individual SKUs, stores, warehouses, channels, suppliers, employees, and transaction types.
How Retailers Can Reduce Shrinkage
Shrinkage cannot usually be eliminated completely, but it can be measured, investigated, and reduced.
The first step is establishing a reliable shrinkage baseline. Retailers should calculate shrink by location, department, product category, and SKU rather than reviewing only a company-wide percentage.
Cycle counting can help identify discrepancies earlier than an annual physical inventory. High-value, high-volume, perishable, or frequently stolen products may need to be counted more often.
Retailers should also use exception reporting. Instead of manually reviewing every transaction, management can focus on unusual patterns such as repeated refunds, excessive discounts, negative inventory, frequent stock adjustments, receiving differences, or transfers that remain unconfirmed.
Employee training is equally important. Staff should understand receiving procedures, product handling rules, return policies, stock adjustment requirements, and the correct response to suspected theft.
Physical security remains useful, but it should be applied strategically. Cameras, electronic tags, controlled stockroom access, improved lighting, secure displays, and store layout changes can deter theft without unnecessarily restricting customers.
Most importantly, retailers should connect loss prevention with inventory management, finance, purchasing, warehousing, ecommerce, and store operations. Shrinkage is not solely the responsibility of a security team. It is an operational and financial issue that requires cooperation across the business.
Using NetSuite to Strengthen Inventory Control
As a retail business grows, identifying shrinkage in retail causes becomes more difficult when transactions are distributed across disconnected systems.
NetSuite can help retailers manage financials, inventory, purchasing, order processing, warehouse activities, and reporting within a connected cloud platform. This creates a more consistent record of how inventory enters, moves through, and leaves the business.
Retailers can gain visibility into inventory across stores and warehouses, monitor transfer activity, review stock adjustments, analyze item-level performance, and connect operational movements with their financial impact.
Role-based permissions and approval workflows can also help limit unauthorized transactions. Meanwhile, reporting and dashboards allow managers to monitor discrepancies and unusual activity without waiting for manually prepared spreadsheets.
NetSuite alone will not prevent every theft or operational mistake. Physical controls, employee training, security procedures, and management oversight remain necessary. However, a connected ERP platform can provide the data foundation retailers need to identify patterns, investigate losses, and respond more quickly.
For retailers managing multiple locations, high transaction volumes, and expanding sales channels, this visibility can turn shrinkage from an unexplained year-end adjustment into a measurable operational issue.
Turning Shrinkage Data Into Better Retail Decisions
Understanding shrinkage in retail causes requires retailers to look beyond missing merchandise. Shrinkage can originate from shoplifting, employee theft, receiving discrepancies, inaccurate data entry, damaged products, pricing mistakes, return fraud, self-checkout errors, and poorly controlled inventory transfers.
These losses often remain hidden because they are spread across different departments and systems.
A successful shrinkage reduction strategy combines accurate inventory records, frequent cycle counts, standardized processes, employee accountability, physical security, exception reporting, and connected business data.
Retailers should not treat every inventory discrepancy as theft. They should investigate why the discrepancy occurred, determine whether it represents a recurring pattern, and correct the process that allowed it to happen.
When inventory data becomes more accurate, retailers can replenish products more effectively, reduce unnecessary purchasing, improve product availability, protect margins, and provide a more reliable customer experience.
Shrinkage may never disappear entirely. But with stronger controls, better visibility, and faster analysis, retailers can prevent many losses from remaining unexplained—and stop small inventory problems from becoming major threats to profitability.
