A Complete Guide to Inventory Analysis

Featured Post Image

Inventory management is inherently connected to the success of your ecommerce company. If your inventory management is handled poorly, there’s a good chance you’ll experience product stockouts or have too much capital tied up in your existing SKUs. However, when your inventory management strategy includes inventory analysis, benefits abound. 

Not only does inventory analysis help guarantee you have the right amount of inventory available, but it reduces your operational costs and promotes better demand forecasting, too. By streamlining your inventory management via inventory analysis metrics, you’ll have a greater understanding of stock counts and your overall operating efficiency, as well.

What is Inventory Analysis?

Inventory analysis is a process for examining inventory levels to determine the ideal amount your company should carry. With careful inventory analysis, you can gain practical insight around the profitability of your inventory, and have an easier time keeping up with fluctuations in customer demand. What’s more, inventory analysis is foundational to increasing sales and controlling costs at the same time. That’s because these calculations identify product trends to help reduce stockouts, boost fulfillment, and improve your supply chain management.

4 Benefits of a Sound Inventory Analysis Strategy

Conducting routine inventory analyses helps to keep your inventory management on track and can really increase efficiencies over time. Some of the greatest benefits to a sound inventory analysis strategy include always having enough stock, accuracy of demand forecasting, less capital tied up in inventory, and a more streamlined supply chain process. 

1. Always have enough inventory on hand

An inventory analysis strategy targets a range of product identifiers — in demand, essential, scarce, and so on — that are necessary for keeping the right products (in the right quantities) on your warehouse shelves. Using stock analysis, your ecommerce company can ensure it has just enough inventory items on hand to avoid stockout or overstock situations.

2. Accurately forecast inventory

More often than not, dead stock is the result of inaccurate inventory forecasting, which is why it’s crucial to have an inventory analysis system in place. A trusted inventory analysis strategy will collect data on all your SKUs, which ultimately improves both forecasting and reordering accuracy. In addition, these insights can also be used to adjust pricing (and increase revenue). 

3. Tie up less capital in inventory

Speaking of cashflow, it’s common for manufacturers and retail businesses to have the bulk of their capital tied up by inventory. Thankfully, with effective inventory analysis, your company can get a good grasp on its lead times (as well as customer demand), so you can better prepare with safety stock or stop buying inventory that doesn’t sell. This translates to less excess or stagnant inventory, which only serves to take up space and incur greater carrying costs. 

4. Streamline your supply chain

Inventory analysis is vital to supply chain optimization, since it can help you consolidate suppliers or shift to single sourcing (to reduce overhead and simplify your operations). On top of that, inventory analysis offers visibility into the product life cycle (launch, growth, maturity, etc), which is paramount to supply chain productivity and keeping stock levels where they need to be. 

4 Inventory Analysis Methods

Depending on what kind of business you run (i.e. what types of inventory you carry), you can leverage a few different inventory analysis methods. Today, some of the most well-known and widely-used strategies include ABC, HML, VED, and SDE analysis — all of which serve a designated purpose and have advantages for specific business models.

1. ABC

One of the most popular methods for inventory analysis is ABC, or ‘Always Better Control.’ With ABC analysis, retailers can classify their inventory based on each items’ consumption value and impact on annual inventory costs. The ABC approach divides goods into one of three categories: (1) A-inventory: the most valuable products, with the largest contribution to profits; (2) B-inventory: ‘interclass’ goods, falling between the most valuable and least valuable products; (3) C-inventory: account for the small transactions that are vital to collective profit margins, but their average cost doesn’t matter much on an individual level. 

ABC analysis allows you to give your most important inventory additional time and focus, thus boosting revenue and helping control your costs. Moreover, utilizing an ABC strategy can reduce dead stock, optimize inventory turnover rate, and assist with demand forecasting. 

2. HML

HML analysis classifies or measures inventory according to the cost per item (per piece). This type of inventory management analysis also segments products into three categories: (1) High Cost: high unit value item; (2) Medium Cost: medium unit value item; (3) Low Cost: low unit value item. While these items should always be listed in descending order of unit value, it will be up to you to fix limits for these categories as you see fit.

Although HML only considers an item’s unit price — in other words, it doesn’t take into account the sales value of each item — it’s still quite useful for controlling costs and staying on budget. 

3. VED

VED analysis is based on inventory value, meaning how important it is for an item to be in stock. Most often, the VED approach is used by manufacturing companies who likely stock a variety of different components and parts. Unlike ABC analysis, VED is only concerned about how necessary an item is to the continuing operation of your business. VED inventory is typically broken down into three categories: (1) Vital: inventory that must be in stock; (2) Essential: a minimum amount of these items will suffice; (3) Desirable: these goods are optional to stock. 

With this classification in mind, a VED analysis is done to determine the true necessity of an item and its effect on production and/or other operational services.

4. SDE

The SDE inventory analysis method is centered around the scarcity of items in the market, or how soon your company can acquire the goods it needs. In that way, SDE analysis looks at what inventory is available, and classifies each item or SKU according to the scarcity of supply.

With this approach, scarce products are usually imported, which means they may take longer to arrive (or the supply may be harder to come by). 

SDE analysis also involves three divisions of inventory: (1) Scarce: imported items with longer lead times; (2) Difficult: goods whose lead time ranges from a few weeks to six months; (3) Easily available: items which are readily acquired. Businesses who utilize the SDE method often deal with raw materials or similar items (with a long lead time prior to acquisition). 

5 Most Important Metrics For Your Inventory Analysis

A detailed, in-depth inventory analysis will use a series of key performance indicators (KPIs) to tell you straight away how your business is doing. Among the most effective (and important) metrics for inventory analysis are inventory turnover ratio, inventory write-offs, gross margin return on investment, days inventory outstanding, and stockout rate. 

1. Inventory turnover ratio

Inventory turnover ratio measures how many times a company sold and replaced (i.e. turned over) its inventory during a specific period of time. Inventory turnover can actually affirm the efficiency of your business, seeing as a higher turnover rate is associated with selling a lot of merchandise (without stocking too much inventory). To calculate turnover for yourself, you can use the formula: inventory turnover ratio = [cost of goods sold ÷ average inventory].

2. Inventory write-offs

An inventory write-off gives formal recognition to the portion of your inventory that no longer has value. In general, an inventory write-off is recorded in one of two ways: (1) it’s expensed directly to your cost of goods sold (COGS) account, or (2) it might offset your inventory asset account. Write-offs happen when stock becomes damaged, spoiled, obsolete, or stolen; if inventory only decreases in value — and is not lost completely — it’s often written down instead of written off.

3. Gross Margin Return on Investment (GMROI)

This gross margin return on investment (or GMROI) tells business owners the amount of money they got back for every dollar they spent on inventory. That is to say, GMROI measures your profit return on the funds invested in your stock. To calculate GMROI for your own company, use the formula: GMROI = [gross margin ÷ average inventory cost].

Gross Margin Return on Investment (GMROI)

An answer above one means you’re selling goods for more than what you paid for them; likewise, a number below one means you are selling them for less than their cost price.

4. Days Inventory Outstanding (DIO)

Days inventory outstanding (DIO) — sometimes called ‘days in inventory’ — has to do with the average number of days you hold your inventory before selling it. This particular metric reveals how quickly a company can turn inventory, meaning it’s a wonderful indicator of operational and financial efficiency. To find your brand’s unique DIO, you can use the formula: days inventory outstanding = [average inventory ÷ cost of sales] x number of days in period.

5. Stockout rate

Stockout rate is the percentage of items that are unavailable on the requested need date from the buyer. This KPI highlights a company’s inability to deliver products from stock within the advertised (or contractually agreed upon) window due to insufficient inventory. Stockout rate is often used to gauge the effectiveness of inventory replenishment within distribution networks. The stockout formula is: stockout rate = [frequency of stockouts ÷ annual sales volume].
