Inventory metrics play a pivotal role in business intelligence as they aid managers and professionals in achieving or surpassing their core objectives. By optimizing processes and enhancing the business value, these metrics prove to be indispensable. It is crucial to establish and monitor inventory Key Performance Indicators (KPIs) for your business to assess and enhance overall performance. While accumulating vast amounts of data is significant, it is equally important to possess the skills to process, analyze, and visualize the most crucial insights of your business. Accessing comprehensive data is imperative to make well-informed decisions that positively impact your business's financial outcomes.

What Are Inventory Metrics?  

Inventory metrics are performance indicators that enable you to effectively monitor, measure, and evaluate your operations. By providing insightful information, they empower you to optimize and enhance your processes. These metrics are specifically designed to concentrate on particular areas and objectives, allowing you to identify trends and weaknesses. Key Performance Indicators (KPIs) for inventory management can be applicable across various industries. Therefore, it is not surprising to find a logistic KPI also categorized as a retail KPI, for example.

By establishing clear goals to achieve on a weekly, monthly, quarterly, or yearly basis, these metrics eliminate uncertainties. They provide you with valuable data that enables you to make strategic and well-informed decisions that positively impact your business. In essence, they support the development of effective behaviors, strategies, and choices. Furthermore, they contribute to enhancing punctuality in deliveries, reducing operational costs, increasing customer satisfaction, and optimizing transportation, among other benefits.

 

Guidelines for Selecting the Appropriate Inventory Key Performance Indicators

When deciding on the most trustworthy and effective metrics for inventory management, consider the following recommendations:


Avoid Vanity Metrics

While utilizing professional KPI tools, it may be tempting to opt for easily attainable indicators that merely showcase efficiency. However, it is crucial to prioritize metrics that demonstrate enhanced effectiveness, as they provide more valuable insights. This also pertains to 'vanity metrics' that may create a facade of process efficiency within the department, but fail to provide actionable information on improving inventory management effectiveness.

Focus on Addressing Business Inquiries

Similarly, it is crucial to refrain from adopting Key Performance Indicators (KPIs) with a broad scope. Such indicators will not provide prompt or valuable insights for taking action or making decisions. The key to selecting appropriate indicators is to consistently align them with your organization's strategic goals.

Keep Customers in Mind

Inventory management entails complexities that should not be disregarded, particularly in terms of operational, supply chain, and customer satisfaction metrics. After all, your customers are the ultimate recipients of your inventory. If they receive incorrect or delayed items, or if out-of-stock situations persist for too long, it will give the impression of poor inventory management and leave them dissatisfied. This could potentially result in reduced customer loyalty.

Monitoring Trends

To effectively track trends and identify inefficiencies in your processes, it is crucial to compare current information with past performance and establish a Key Performance Indicator (KPI) scorecard template that can be applied to various business scenarios related to inventory measures and metrics. By doing so, you can gain insights into any issues with your out-of-stock rate over the past weeks or months and delve deeper into the underlying causes. This proactive approach will enable you to take appropriate actions at the right time.

Avoid Sole Reliance on Numbers

While numbers hold significant value, it is equally important to prioritize the quality, end-users, customers, and partners when aiming for business growth. Merely focusing on monitoring numbers without considering the human aspect may lead to potential bottlenecks in the long term.

 

Selecting Inventory Metrics  

Considering the significance of cost factor and customer experience in inventory management for contemporary businesses aiming to thrive in the fiercely competitive digital age, let's explore a selection of key inventory Key Performance Indicators (KPIs) that specifically address these crucial aspects.

Inventory Accuracy

Without accurate knowledge of your stock and movement within your warehouse, running a successful business becomes challenging. Conducting regular cycle counts and adopting electronic tags can simplify the task and offer essential data for comparing physical inventory with electronic records. This inventory Key Performance Indicator (KPI) holds great significance as it can either make or break your business. Failure to have the items you sell online readily available in stock, for example, can severely damage your business operations. Additionally, this metric plays a vital role in identifying potential issues associated with shipping, receiving, and accounting processes.

Inventory Turnover

The inventory turnover is a key performance indicator (KPI) that examines the number of times your entire inventory is sold within a specific time frame. This KPI can be calculated by dividing the cost of goods sold by the average inventory. It serves as a useful metric for assessing the efficiency of production planning, processes, marketing, and sales management. Essentially, the higher the inventory turnover, the better. A low turnover, on the other hand, indicates difficulties in converting stock into revenue. In such cases, it is crucial to identify and address any bottlenecks in your supply chain process.

Out-of-Stock Rate Inventory KPI

Efficient inventory management plays a crucial role in satisfying customer demands, especially within the fast-moving consumer goods (FMCG) industry. While it is essential to prevent depletion of stock, there may be instances where certain products are temporarily unavailable due to various factors. In such cases, it is important to closely monitor this rate and identify the specific items and timings of unavailability. For instance, in the provided example of our inventory KPI, the end of the workweek exhibits the highest percentage of out-of-stock rates.

Customer Retention and Loyalty

By ensuring streamlined processes for order picking, packing, and timely shipping of accurate orders, you can reinforce customer satisfaction and encourage repeat business. Furthermore, contented customers are inclined to refer your brand to their friends and relatives, making this act of advocacy more influential and impactful than any creative advertisement you can develop. Measuring this referral potential can be achieved through a customer service Key Performance Indicator (KPI) such as the net promoter score (NPS), which evaluates the strength of your customer referrals.

Carrying Cost of Inventory

One of the most crucial inventory KPI metrics is known as the carrying cost of inventory. It provides a comprehensive overview of all expenses related to storing unsold goods. These expenses encompass various aspects such as warehousing, insurance, employee costs, damages to goods, rent, utilities, and more. Accurately monitoring the carrying cost of inventory is vital at all times as it offers valuable insights into whether production should be increased or decreased. Maintaining a balanced equation between income and expenses depends heavily on this inventory management KPI.

Warehousing Costs

The warehouse indicator assesses the financial implications associated with overseeing your warehouse. Activities such as ordering, storing, and loading inventory require sufficient funding for successful execution. Additionally, there are human expenses including labor, transportation, and delivery that should not be overlooked. Evaluating warehouse costs is not a straightforward task, hence it is crucial to approach it diligently and avoid any omissions. When accurately carried out, this assessment streamlines overall management and brings added value, often earning recognition from senior management and investors.

Average Time to Sell

This metric is particularly significant in the FMCG industry, where adherence to food safety and management regulations is crucial to avoid potential legal obstacles. It is imperative for any industry that operates within international and local legal frameworks to monitor this widely recognized inventory metric. The significance of tracking this metric becomes even more evident when considering the nature of the FMCG industry. The average time to sell serves as a key KPI for inventory control, offering valuable insights into storage processes and guiding the development of procurement strategies.

Inventory to Sales Ratio

The subsequent illustration on our inventory KPI roster is equally centered on financial aspects. This particular metric aid in assessing the surplus stock and also indicates the company's capability to handle unforeseen scenarios. It is calculated by dividing the available inventory for sale by the actual quantity sold. When combined with inventory turnover or carrying costs, it offers comprehensive insights into the financial solidity of your business and aids in determining the desired course of action.

On-shelf Availability

This entails ensuring that products remain stocked on shelves, easily reachable, and prominently displayed. This evaluation links with other performance indicators like the rate of products being out-of-stock and lost sales. It encompasses three crucial aspects: availability at the shelf, in-store, and in the warehouse. For instance, cutting-edge software can monitor data in real-time and present advanced charts that promptly generate actionable insights. This eliminates the need for users to manually sift through numerous papers or spreadsheets in search of information.

Dock to Stock

This particular key performance indicator (KPI) focuses on monitoring the time taken for inventory to be securely stored on warehouse shelves and made available for shipping to customers. It is derived from the duration starting from when inventory departs the supplier's warehouse, through unloading and inspection, until it becomes ready for picking, packing, and shipping. This metric can pose a challenge in terms of tracking given that several steps within the process are beyond the company's complete control and depend on the supplier. Nevertheless, subpar performance in this area may signify inventory management issues that could result in delayed orders and dissatisfied customers.

Dead Stock 

The dead stock refers to inventory that has reached the end of its lifecycle, indicating minimal chances of being sold in the near future. This occurrence is common with seasonal products like swimwear, Halloween, or Christmas items, among others. Monitoring dead stock is crucial for efficient inventory management, as these items take up valuable space in your warehouse that could be better utilized for high-demand products. Hence, closely tracking and eliminating unnecessary items can significantly impact your inventory management efforts.

Stockouts

A stockout can occur due to various factors, such as delays from suppliers, insufficient demand forecasting, supply chain disruptions, shortage of working capital, or inadequate cash flow management, among others. Experiencing a stockout can have several repercussions, primarily impacting sales and, more importantly, customer satisfaction and loyalty. When a customer seeks a product and discovers it is out of stock, they are highly likely to seek alternative options elsewhere, significantly diminishing the likelihood of their return to your company.

Order Status Inventory Metric

Monitoring the status of your orders in real-time is crucial for prompt action in addressing any potential issues. This acts as a key performance indicator (KPI) for inventory management, linking your business to your customers. To effectively assess your supply chain metrics and strategies, it is essential to have real-time visibility into the progress of your orders, including shipping, receiving, packaging, and cancellations. This enables better inventory management, reduces restocking needs, and enables you to focus on generating a higher volume of new orders to sustain your business.

Order Cycle Time

Tracking the order cycle time is a crucial metric in inventory management as it provides insight into the overall efficiency of your supply chain. This metric essentially calculates the duration from when a customer initiates an order to when they receive it. While measuring the order cycle time for each individual order would be ideal, businesses commonly opt for an average order cycle time to maintain a more realistic measurement. This is achieved using the following formula: Average Order Cycle Time = (Delivery Date – Order Date) / Total Orders Shipped.

Sell-through Rate

This inventory metric is a crucial component of a retail KPI dashboard, specifically designed to enhance retail performance. By examining your sell-through rate, you can effectively analyze the relationship between the inventory received and sold within a specified timeframe. This valuable insight enables you to monitor and improve your sell-through performance, allowing targeted enhancements to essential aspects of your sales and merchandising procedures.

Average Inventory Level

The average inventory level provides a straightforward snapshot of your business's mean inventory level during specific time durations. It is a valuable metric for businesses aiming to optimize their operations. This metric offers a precise overview of the quantity of inventory your business typically maintains throughout the year.

Backorder Rate

The backorder rate serves as a valuable tool for monitoring the number of goods or items that cannot be fulfilled when a customer places an order. Harnessing the power of these enlightening inventory accuracy metrics allows you to establish a clear fulfillment objective and effectively monitor your progress on a weekly, monthly, or annual basis. This enables you to precisely identify the factors contributing to fluctuations in the backorder rate during specific periods and make strategic adjustments to enhance or modernize your supply chain processes for optimal results.

Rate of Return

The rate of return serves as a key performance indicator (KPI) in inventory management, determining the proportion of sold products that are ultimately returned within a given timeframe. Various factors can influence an upward trend in this rate, such as inaccurately provided sizing guides, misrepresented colors, or faulty items, among others. It is crucial to strive for reduced return rates to not only enhance customer satisfaction and loyalty, but also to mitigate the increased costs inflicted upon the supply chain as unsold inventory must be stored.

Gross Margin Return on Investment

Gross Margin Return on Investment is a vital inventory management metric that elucidates the relationship between income and investment. It unveils the exact amount of profit generated by your business in comparison to the funds allocated towards stock or inventory during a specific timeframe. This insightful data enables you to strategically enhance your GMROI by prioritizing investments in inventory that consistently yield substantial returns, while concurrently minimizing expenses on items that consistently hinder your business growth or disproportionately deplete your budget.

Time to Receive

Time to receive is a crucial key performance indicator (KPI) in any inventory management dashboard. This metric provides a detailed analysis of stock flow and movement. By tracking this indicator visually, you will gain a thorough understanding of the speed at which your team or staff brings in stock and puts it on the shelves. Furthermore, it helps gauge the efficiency of preparing the stock for sale. Consistently benchmarking this metric is highly beneficial as it allows you to identify emerging trends. If you observe a slowdown in your time to receive rates, it indicates the presence of inefficiencies within your warehouse operations.

Inventory Shrinkage

This metric measure the variance between your documented inventory levels and the actual quantity stored in your warehouse. Discrepancies can occur due to various factors such as damage during shipping, vendor fraud, human counting errors, or even theft. To minimize this shrinkage, several effective measures include conducting frequent inventory audits, automating the counting process, installing surveillance cameras, regularly evaluating vendors, and providing theft prevention training to employees, among other strategies.

Days of Inventory

The DSI metric is widely used to measure the duration it takes for an organization to sell its existing inventory. Ideally, a lower DSI signifies that the company can efficiently convert inventory into sales. Although experts suggest that a desirable DSI should fall between 30 and 60 days, it is important to note that there is no fixed benchmark value for this metric as it varies across industries.

Labor Cost per Item

The metric known as unit labor cost is a key performance indicator (KPI) that evaluates the expenditure incurred by a company in producing a single item from a labor standpoint. Monitoring this metric is crucial as labor expenses significantly impact the carrying costs associated with inventory. Furthermore, analyzing labor costs as a singular indicator enables a more meticulous breakdown of expenses, facilitating optimization opportunities. To accurately gauge this KPI, it is essential to establish a tracking period, such as weekly, monthly, quarterly, or annually.

Inventory Management Best Practices

Manufacturing companies rely on various data sets encompassing trends such as seasonal patterns, price points, buying behaviors, and other relevant information to ensure a consistent supply for retailers. In order to effectively manage restocking, retailers also require data-driven insights. Additionally, Fast-Moving Consumer Goods (FMCG) companies rely on accurate data to optimize their daily processes and ensure fresh product availability. To acquire expertise in inventory management, here are some valuable tips that can be employed:


ABC Analysis for Effective Categorization

To commence, an effective approach for managing inventory is to establish a hierarchical order based on the monetary value of each item. Since all items in stock do not hold the same worth, this methodology aids in directing attention towards those that generate maximum revenue. Categorize them as follows:

  • A-items are regarded as the top-selling products and are given utmost priority. These items require continuous quality assessment and frequent restocking.
  • B-items are valuable products with a moderate priority. Typically, reordering on a monthly basis is adequate for these items.
  • C-items are low-priority items that are usually stocked in large quantities and require minimal restocking.

JIT – Just In Time

Just in Time (JIT) is an inventory management technique that effectively manages cash flow for retailers by purchasing goods from vendors only when an order is received from a customer. While this approach may pose some challenges for manufacturers who require accurate trend data to maintain sufficient stock levels for retailers, it proves highly beneficial for businesses engaged in eCommerce or the production of personalized items like jewelry, furniture, luxury cars, and services such as events, food, or garage-related services.

Be Data-driven

This practice will enable you to identify regular patterns, trends, as well as bottlenecks and inconsistencies. Consequently, you can determine how to enhance your processes and optimize efficiency. Capitalizing on the numerous benefits offered by data analysis tools allows you to distinguish yourself from competitors and further enhance your efficiency. The user-friendly drag-and-drop interface facilitates convenient data consolidation and analysis. Moreover, these tools simplify the visualization of insights and empower you to convey them effectively through inventory dashboards.

Implement Quality Control

Quality control is paramount for every business and should be initiated as early as possible. It is imperative to establish quality control procedures to ensure customer satisfaction and continuous business growth. To maintain an effective quality control process, make certain that all employees are well-informed about various aspects such as adhering to a reception checklist, monitoring for damages, and ensuring product compliance. Should an item fail to meet our company's quality standards, it will be returned to the supplier, resulting in a reduction of stock levels.
