Inventory Analysis Explained: 5 Metrics & Strategies to Try

A good inventory management strategy is the backbone of any successful eCommerce company. Without it, you will find yourself with stockouts or too much capital tied up in your existing SKUs. But when you have an effective plan that includes analyzing what products are needed and not wanted, there’s more opportunity for success.

Inventory analysis ensures that you have the right amount of inventory available, reduces your operational costs, and promotes demand forecasting. Click To Tweet

By streamlining your inventory management via metrics related to stock counts and operating efficiency, you will better understand what is going on with both.


What is an Inventory Analysis?

Inventory analysis is a process that helps you determine the best amount of inventory to carry. You can use it as a guide for your company’s profitability and identify trends in customer demand to help forecast sales.


Why You Need Sales and Inventory Analysis Strategy

A sound inventory analysis strategy can help you maintain a good supply of products and have an accurate forecast. This will free up capital, save time in managing your collections, and simplify the process of procuring new items.

1. Have enough inventory always

To avoid overstock or out-of-stocks, a company needs an inventory analysis strategy that considers the demand and availability of different products. An eCommerce business can use stock analytics in conjunction with their supply chain information to ensure they have just enough on hand.

2. Forecast inventory accurately

Inaccurate inventory forecasting is the most common cause of deadstock, so it’s essential to have an analysis system in place. An analysis strategy will collect data on your SKUs and forecast and reorder accuracy or adjust pricing.

3. Tie up less inventory capital

It’s not uncommon for manufacturers and retailers to have most of their money tied up in inventory. Luckily, practical inventory analysis can help you get an idea about your lead times (as well as customer demand) so that you know when it’s time to buy more or stop buying items if they’re sitting around.

4. Streamline the supply chain

An inventory analysis can help you consolidate suppliers or shift to single sourcing, reducing overhead and simplifying operations. On top of that, an inventory analysis provides visibility into the product life cycle- launch, growth, maturity -which is paramount for productivity in your supply chain.


Standard Methods of Inventory Analysis

Several different inventory analysis methods can be used depending on the type of business you run. The most well-known and widely-used strategies include ABC, HML, VED, and SDE — all of which serve a designated purpose with advantages for specific types of businesses.

1. ABC

ABC analysis is a method for inventory management that divides goods into three categories: A, B, and C. Goods are classified according to their consumption value, affecting the cost of annual inventory.

One of the most important things for a business is having inventory. A-inventory is a product with high margins and represents significant portions of profits.

(2) “B-inventory” – products that are not the most expensive and also not the cheapest.

Using ABC analysis allows you to give your most important inventory additional time and focus, boosting revenue. It also reduces dead stock because it optimizes inventory turnover rate while helping with demand forecasting.

2. HML

HML analysis is a type of inventory management that classifies or measures items by their cost per item. This type of classification also divides products into three categories:

It turns out that a paycheck is not the only thing that matters.

(2) Medium Cost: items priced at an average price.

Low-cost items, such as clothing and food, should always be listed in descending order of unit value. You will need to set limits for these categories on your own.

Although HML does not account for an item’s sales value, it is still a helpful tool in budgeting and controlling costs.

3. VED

VED analysis is different from ABC because it measures the importance of an item to your business by how much inventory you have. VED breaks down things into three categories: necessary, discretionary, and peripheral.

(1) A company needs to keep a certain amount of inventory on hand.

(2) Essential: enough of these items will be needed to start with.

For retailers, it is essential to offer optional goods.

VED analysis is a way to ensure that an item will sell and be profitable.

4. SDE

The SDE inventory analysis method is centered around the scarcity of items your company can acquire. The system looks at what supply you have and how soon it will be available, so when demand for a commodity increases, there are more options to buy from.

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). 

The three inventory divisions included in SDE analysis are Raw materials, work-in-process, and finished goods.

(1) Scarce: items that take longer to be delivered because they are imported.

The SDE method typically deals with raw materials or similar items that are not readily available.


Inventory Analysis Metrics to Track

A detailed inventory analysis will tell you what your business is doing by using a series of key performance indicators. Among the most effective and important metrics for an inventory analysis are turnover ratio, write-offs, gross margin return on investment, days outstanding in stockouts.

1. Inventory turnover ratio

Inventory turnover is how many times a company sold and replaced inventory during a specific period. It can tell you whether or not your business is running efficiently because it shows what items are being turned over in less time, which means they were likely more popular with customers. You calculate this by dividing the cost of goods sold by average inventory.

2. Inventory write-offs

If you have inventory that has gone bad, is out of date, or is not worth what it once was, then an inventory write-off can be used to acknowledge the loss formally. The process might involve expensing the cost directly into your COGS account or using a journal entry to offset any remaining value in your assets.

3. Gross Margin Return on Investment (GMROI)

When it comes to managing your inventory, you need to know the return on investment. This is calculated by dividing gross margin by the average cost of goods sold (COGS). The formula for GMROI looks like this: GMROI = [gross margin ÷ COGS]

A higher than one number means you are selling the product for more money than what it cost to buy, and a number below one would mean your profit margin.

4. Days Inventory Outstanding (DIO)

This metric is a good indicator of operational and financial efficiency. The formula for calculating this number is days inventory outstanding = [average inventory ÷ cost of sales] x number of days in the period.

5. Stockout rate

The stockout rate is the number of times a company cannot supply an item on demand. This KPI highlights how your inventory meets infrequent customer needs by measuring annual sales volume.
