Incorrect item entry: A source of retail shrinkage
Incorrect item entry is a common challenge in retail: frustrating for shoppers when it happens by mistake, and costly for retailers regardless of intent. It can lead to shrinkage, inaccurate stock levels, and reduced margins. Want to understand how and why it happens? Learn more here.
This is incorrect item entry
Incorrect item entry in self-service occurs when the wrong item is registered in the system. This results in the shopper paying the wrong price and creates errors in stock levels for the retailer. It can be frustrating for both shoppers and retailers—and is a common source of shrinkage.
How does incorrect item entry occur?
Here are the top 5 causes of incorrect item entry in self-service:
1. Unclear product identification
Customers may struggle to identify the correct item, especially when it comes to fresh produce, similar-looking products, or unclear naming in the system. For example, distinguishing between different types of vegetables can be tricky, particularly when considering different producers, organic vs. non-organic options, and similar variations.
2. Technical issues
Everything works well—until it doesn’t. Problems with scanners, scales, touchscreens, or software can lead to incorrect registrations or force customers to choose alternatives. It is therefore vital for retailers to provide the best possible conditions to support their customers, especially as self-service requires a higher level of autonomy.
3. Faulty or missing barcodes
Damaged, incorrect, or missing barcodes can prevent proper scanning, leading customers to manually select the wrong item. Even when products appear to have the correct label, barcode errors can result in incorrect registrations. It is therefore essential for retailers to label products accurately and ensure that the labels are durable.
4. Poor user interface or store setup
A confusing interface, unclear categories, or poor product organisation can make it difficult for customers to find the correct option—leading to mistakes. This also highlights the importance of retail staff: having someone available to assist can quickly resolve confusion.
5. Intentional misidentification
Some individuals deliberately select or scan a cheaper item instead of the correct one in an effort to save money. This type of behaviour can be difficult to prevent, even with clear product identification and advanced technology. However, there are measures that can be taken to reduce it—these will be explored further ahead.
To tackle shrinkage caused by incorrect item entry, it is important to understand its different causes and distinguish between intentional and accidental shrinkage.
Intentional vs. Accidental shrinkage
Not all shrinkage is intentional. In fact, a large portion of the shrinkage associated with self-service options is accidental. Shoppers usually want to do the right thing, but a lack of knowledge, unclear instructions, or faulty technology can create obstacles. It is therefore important to distinguish between intentional and accidental shrinkage.
Intentional shrinkage occurs on purpose—for example, when shoplifters take items without paying, or when individuals use skip-scanning or barcode switching to pay less than they should. It can be caused by both internal and external factors.
Accidental shrinkage, on the other hand, does not happen deliberately. However, it can still result in significant losses for retailers if not identified. Like intentional shrinkage, it can also stem from both internal factors, such as faulty inventory management, and external factors, such as customers misusing self-service solutions.
One of the challenges with incorrect item entry is that it can be either intentional or accidental. For example, an individual might use an in-store scale to register a cheaper product on purpose. However, it may also happen because the person is unsure which product to select and chooses the option that seems most likely to be correct.
These are just some of the risks associated with incorrect item entry—so how can retailers ensure that these, whether intentional or accidental, are kept to a minimum?
How to prevent incorrect item entry
There are plenty of ways to ensure incorrect item entry is low – whether it happens accidentally or with intent. Here are some of the most effective ways to prevent incorrect item entry.
1. Clear instructions and guidance
Provide simple, intuitive instructions throughout the self-service journey. This helps minimise accidental errors, especially for first-time users or when handling complex items like fresh produce. Ensure that product details, such as name, type, or category are clearly visible, making it easy for shoppers to select the correct item.
2. User-friendly interface and product structure
Ensure the system is easy to navigate, with clear categories, images, and product names. The easier it is to find the correct item, the lower the risk of mistakes. The user experience impacts not only item registration but the overall shopping journey, making it essential to continuously review and improve the interface.
3. Multiple control mechanisms
Combine technologies such as cameras, weight verification (scales), and barcode validation to detect mismatches and reduce both accidental and intentional errors. Today, several solutions are available — such as AI-powered scales that detect incorrect items, and devices like the Joya Smart, which register items using both barcode scanning and built-in cameras.
4. Staff presence and support
Staff members are more important than ever, especially as new retail solutions are introduced. Having staff available near self-service areas allows customers to ask questions while also helping to deter dishonest behaviour. Staff can also step in when suspicious activity is detected.
5. Smart alerts and behavioural monitoring
Use algorithms to identify unusual patterns, such as repeated incorrect entries or inconsistent behaviour, and trigger alerts only when necessary. Some retail solutions, such as EasyShop, include built-in algorithms that help retailers quickly detect these behaviours. By implementing multiple levels of security, retailers can also adapt protection based on their customer base — and even individual shoppers.
6. Reliable product data and labeling
Sometimes the shopper does everything correctly, but errors still occur. Ensure that barcodes, PLUs, and product information are accurate and up to date. As 2D barcodes are being implemented in retail, it is vital to have the correct label and information. Clear, durable labels further reduce the risk of incorrect item selection.
Incorrect item entry can occur for a variety of reasons. However, by being well-prepared and providing the right conditions, retailers can both prevent and detect these errors. Combining smart retail solutions not only helps reduce incorrect item entry, but also addresses other forms of shrinkage, such as skip-scanning and barcode switching.
