Shrinkage is a term used to describe the difference between a store’s actual inventory and its recorded inventory. It most commonly refers to retail businesses, but in truth, any business that holds physical inventory will encounter shrinkage at some point.

Aspect	Explanation
Concept Overview	– Shrinkage in business and retail refers to the unexplained reduction in inventory or the loss of goods between the point of purchase or production and the point of sale. It is a common challenge faced by retailers, manufacturers, and businesses that manage physical inventory. Shrinkage can result from various factors, including theft, fraud, damage, errors, and inefficiencies in the supply chain. Managing shrinkage is crucial for controlling costs, maximizing profits, and maintaining inventory accuracy.
Types of Shrinkage	– Shrinkage can be categorized into several types: 1. Shoplifting: Theft by customers in retail stores. 2. Employee Theft: Internal theft by employees, which may involve theft of cash, products, or merchandise. 3. Administrative Errors: Mistakes in record-keeping, pricing, or inventory management. 4. Supplier Fraud: Dishonest practices by suppliers, such as sending fewer goods than ordered. 5. Damage and Spoilage: Loss due to damage, spoilage, or expiration of goods. 6. Process Inefficiencies: Losses occurring in supply chain processes, such as handling, storage, or transportation. 7. Unknown Causes: Losses that cannot be attributed to a specific cause.
Impact on Businesses	– Shrinkage has significant implications for businesses: 1. Financial Loss: Direct financial losses due to stolen or damaged inventory. 2. Reduced Profit Margins: Erodes profit margins and affects overall financial health. 3. Increased Costs: Requires additional investment in security measures and loss prevention efforts. 4. Inventory Inaccuracy: Leads to inaccurate inventory records, affecting demand forecasting and inventory management. 5. Customer Satisfaction: May result in stockouts and impact customer satisfaction. 6. Legal and Regulatory Consequences: Can lead to legal issues, fines, or regulatory violations.

Understanding shrinkage

Shrinkage describes a discrepancy between the actual inventory and recorded inventory of a business.

According to the 2021 National Retail Security Survey, the average shrinkage rate for United States retail businesses was 1.6%. With total retail sales of $5.15 trillion in 2021, the losses attributable to shrinkage equate to approximately $88 billion.

Key Concepts

Types of Shrinkage: Shrinkage can be categorized into several types based on the underlying causes:
- Inventory Theft: Intentional or unauthorized removal of inventory by employees, customers, or external parties, often referred to as inventory shrinkage or shrink.
- Damage and Spoilage: Losses resulting from physical damage, deterioration, or spoilage of inventory during handling, storage, or transportation.
- Administrative Errors: Mistakes in recording inventory transactions, such as data entry errors, miscounts, or discrepancies between physical counts and system records.
- Obsolete Inventory: Reductions in inventory value due to obsolescence, expiration, or changes in demand, rendering products unsellable or obsolete.
Shrinkage Rate: Shrinkage rate is a key performance indicator (KPI) used to measure the extent of inventory shrinkage relative to total inventory value or sales revenue. It is typically expressed as a percentage and can vary widely across industries, product categories, and business environments.
Impact on Financial Performance: Shrinkage can have adverse effects on a company’s financial performance, profitability, and cash flow. It erodes profit margins, reduces inventory turnover, inflates cost of goods sold (COGS), and lowers asset values, ultimately impacting bottom-line results and shareholder value.

What causes shrinkage?

Shrinkage is caused by many factors, such as:

Theft – whether that be internal (employee theft) or shoplifting from a customer. The former is common in the hospitality industry where employees manipulate point-of-sale (POS) systems for their own benefit.
Damage – any damage to an item that prevents it from being sold is also a form of shrinkage. It may occur while the item is in transit or as it is being handled. For example, an employee drops a bottle of wine when stacking shelves in a liquor store.
Vendor fraud – as the number of goods in a shipment increases, so too does the chance of shrinkage from vendor fraud. A wholesale wine business that receives 798 cases of wine instead of 800 is less likely to notice the difference. Many vendors take advantage of a buyer’s carelessness or inability to count large order quantities.
Spoilage – when perishable items are not sold before their due date, they must be thrown away. Unsurprisingly, this form of shrinkage is prevalent in supermarkets, restaurants, and other food establishments.
Human error – an often overlooked source of shrinkage is human error. A waiter that pours more than the standard 6 ounces of wine into a glass is causing a loss of inventory that costs the restaurant money. The same idea applies to any situation where food or drink is improperly portioned before the sale.

How can shrinkage be mitigated?

For most businesses, shrinkage is a fact of life. There will always be products that are stolen, damaged, spoiled, or otherwise unaccounted for.

Nevertheless, there are some strategies a business can use to bring its shrinkage rate down:

Utilize frequent cycle counting – this is a principle of good stock management that involves counting a small subset of the total inventory on a regular basis. Focusing on a particular section of a store enables the business to better reconcile its inventory and identify shrinkage patterns as they occur.
Implement shoplifting deterrents – deterring in-store theft starts with training staff to be on the lookout for suspicious behavior. A visible security system is also a worthwhile investment. Beyond these measures, electronic security tags can also be placed on high-risk items. Many supermarkets, for example, place security tags on meat, batteries, razor blades, and premium alcohol.
Create a desirable company culture – since internal theft tends to be caused by employees who are unhappy, unmotivated, or undertrained, establishing a culture of trust to improve morale is key. Some companies have also reduced theft by ensuring that at least two individuals are in a store at any one time. Point-of-sale theft can also be mitigated by having a supervisor or manager sign off on any refund or voided sale request.
Automate inventory management – to eliminate instances of shrinkage that arise from human error, integrated inventory management, and POS system is the answer. These systems allow inventory personnel to monitor shrinkage rates and avoid administrative errors that result when manually entering counts.

Challenges in Shrinkage Management

Managing inventory shrinkage presents several challenges:

Complexity of Detection: Identifying the root causes of shrinkage and distinguishing between intentional theft, operational errors, and other factors can be challenging due to the complexity of supply chains and the multitude of contributing factors.
Resource Constraints: Conducting thorough investigations, implementing preventive measures, and maintaining vigilance require dedicated resources, expertise, and investments, which may be limited for some organizations, particularly small businesses.
Balancing Security and Customer Experience: Implementing stringent security measures to prevent theft and shrinkage must be balanced with providing a positive customer experience and ensuring convenience and accessibility for shoppers.

Real-World Examples

Shrinkage management is a critical concern for retailers, manufacturers, and supply chain stakeholders worldwide:

Retail Loss Prevention: Retailers employ various loss prevention strategies, such as electronic article surveillance (EAS) systems, CCTV surveillance, inventory tracking technologies, and employee training programs, to combat shoplifting, employee theft, and other forms of shrinkage.
Supply Chain Optimization: Manufacturers and distributors invest in supply chain visibility, traceability, and risk management solutions to identify vulnerabilities, optimize inventory management practices, and reduce shrinkage across the supply chain.
Data-Driven Insights: Advanced analytics and machine learning algorithms are used to analyze large volumes of data, identify patterns, anomalies, and predictive indicators of shrinkage, and generate actionable insights for decision-making and risk mitigation.

Key takeaways:

Shrinkage describes a discrepancy between the actual inventory and recorded inventory of a business.
Shrinkage is caused by several factors that are not entirely avoidable. These include employee theft, customer theft, vendor fraud, spoilage, and human error.
To ensure shrinkage rates remain at acceptable levels, businesses can automate inventory management systems, implement shoplifting deterrents, create a culture conducive to trust, and utilize frequent but targeted cycle counting.
