Studies show that inventory inaccuracy can cost businesses up to 10% of their revenue. If you’re ready to turn inventory data into a competitive advantage, this guide is for you. Learn how to track inventory with precision, make better decisions, and maximize profitability.
We will also discuss the common causes of inventory inaccuracies, industry benchmarks, and the long-term benefits of improved inventory accuracy. Let’s get started starting by defining what it is.
What is Inventory Accuracy as a KPI?
Inventory accuracy is a key performance indicator (KPI) for warehouses that measures the precision and correctness of a company’s inventory records compared to the actual physical inventory. In other words, it assesses how well a warehouse’s recorded inventory quantities match the actual quantities of products, materials, or goods in its storage locations.
The formula to calculate inventory accuracy typically involves comparing the recorded inventory levels (as per the company’s records or warehouse management system) with the actual counted inventory during a physical inventory count or audit. The result is often expressed as a percentage or ratio. Here’s the basic formula:
Inventory Accuracy = (Recorded Inventory / Actual Inventory) × 100
A high inventory accuracy percentage indicates that the company’s inventory records are reliable and a good control system is in place. Conversely, a low accuracy percentage suggests there might be issues with inventory management, such as discrepancies due to theft, data entry errors, inaccuracies in order fulfillment, or problems with tracking the movement of goods.
Why is Inventory Accuracy Important?
Accurate inventory data is crucial for any business, regardless of size or industry. It ensures you have the right products available when your customers need them, preventing stockouts and lost sales. Additionally, accurate inventory data enables you to make informed purchasing, production, and pricing decisions, ultimately maximizing profitability.
In addition to improving customer satisfaction and increasing revenue, accurate inventory management streamlines your operations. It eliminates the need for manual stock counts and reduces the time spent searching for items. By optimizing your inventory accuracy, you can create a lean and efficient supply chain that saves you time and money.
When inventory accuracy is low, it can lead to a multitude of problems. Overstocking can tie up capital and result in unnecessary storage costs, while understocking can lead to lost sales and dissatisfied customers.
To improve inventory accuracy, you must understand the common causes of inaccuracies and implement effective strategies to address them. Let’s explore these causes in detail.
Common Causes of Inventory Inaccuracies
Inventory inaccuracies can stem from various sources, and identifying these causes is the first step toward improving accuracy. Here are some of the most common causes of inventory inaccuracies.
1. Data Entry Errors
This pertains to mistakes made when manually entering data into your systems, such as transposing numbers, entering incorrect quantities, or selecting the wrong product codes. These mistakes lead to discrepancies between recorded and actual inventory levels.
2. Lack of Automation
Like the first cause, relying solely on manual processes without proper automation, like barcode scanning or RFID technology, increases the likelihood of errors and inconsistencies in inventory data.
3. Poor Receiving Procedures
Errors during the receiving process can result in inaccurate inventory records. Examples of errors include failing to update inventory quantities upon receipt or failing to report damaged goods accurately.
4. Shrinkage and Theft
Unaccounted shrinkage due to theft, damage, or other reasons can cause discrepancies between recorded and actual inventory quantities.
5. Inadequate Training
Insufficient employee training in inventory management can lead to mistakes in recording, counting, and handling inventory items.
6. Mismatched SKUs/Barcodes
Incorrectly labeling items or using outdated SKUs or barcodes can lead to the misidentification of products, causing inaccuracies.
7. Poor Warehouse Layout and Organization
Inefficient warehouse layout, disorganized storage, or improper product placement can make it difficult to conduct accurate inventory counts.
8. Inadequate Communication
Lack of clear communication between departments (such as purchasing, sales, and warehouse) can result in discrepancies when recording inventory movements.
9. Lack of Integration Between Systems
If your inventory management system is not integrated with other systems, it can result in inaccurate data.
10. Inconsistent Audits
Infrequent or irregular inventory audits and counts can allow discrepancies to go unnoticed for extended periods.
How Do You Ensure Inventory Accuracy?
Now that we understand the causes of inventory inaccuracy let’s explore some practical techniques for improving it.
1. Warehouse Management Systems and Software
Investing in a reliable warehouse management system or software is crucial for maintaining accurate inventory records. These systems provide real-time visibility into stock levels, automate data entry, and enable seamless integration with other business systems. Choose a system that suits your business needs and budget, and ensure it offers features such as barcode scanning, batch tracking, and reporting capabilities.
2. Utilize Barcoding and RFID Technology
Implementing barcoding or radio-frequency identification (RFID) technology allows you to streamline data collection and reduce human errors during receiving, picking, and counting processes.
3. Implementing Cycle Counting for Better Accuracy
Cycle counting involves regularly counting a small portion of your inventory to ensure accuracy. Instead of shutting down operations for a full physical inventory count, cycle counting allows you to identify and address inaccuracies on an ongoing basis. By counting a portion of your inventory each day, week, or month, you can quickly identify and resolve any discrepancies before they become significant problems.
4. Streamlining the Receiving Process
Efficient receiving processes are essential for maintaining accurate inventory records. Train your employees on proper receiving techniques, including checking quantities, inspecting for damages, and accurately recording information. Having clear guidelines and well-defined workflows will help reduce errors and improve accuracy.
5. Training and Empowering Employees
Your employees play a crucial role in maintaining accurate inventory records. Comprehensive training on inventory management best practices, including data entry, picking, and receiving techniques, can significantly improve accuracy. Empower your employees by giving them the tools, resources, and authority they need to manage inventory effectively. Encourage open communication and establish feedback loops to address any concerns or suggestions they may have.
6. Regular Data Validation
Regularly validate and clean your inventory data to eliminate duplicates, incorrect entries, or inconsistencies.
What is a Good Inventory Accuracy?
What does “good” inventory accuracy mean for your business? While 95%+ is the general goal, the right target depends on your industry, products, and risk tolerance. Here’s a breakdown to help you set realistic goals:
- 95-98%: Acceptable for many businesses, especially those with lower-value items or slower turnover.
- 98-99%: Essential for businesses with high-value goods, perishable items, or industries with strict regulations (like medical supplies).
