If the inventory turnover ratio is high, the company handles the inventory well, and the stock is not outdated, which naturally means lower holding costs. With Inciflo, businesses can optimize their inventory management, enhance supply chain efficiency, and ensure they maintain the ideal inventory days number for their industry. DSI should be calculated regularly, ideally at the end of each accounting period, which could be monthly, quarterly, or annually. This frequency allows businesses to keep a consistent track of inventory efficiency and make timely adjustments.
- Inventory efficiency is a critical measure of how well a company manages its stock.
- ShipBob’s inventory management software (or IMS) provides updated data so that you can make more informed decisions when managing your inventory.
- Prepare for future growth with customized loan services, succession planning and capital for business equipment.
- For example, costs can include the likes of labor costs and utilities, such as electricity.
- If your business experiences predictable spikes (holiday surges and seasonal slumps), your DSI value will typically fluctuate throughout the year.
It’s about having the right amount of products at the right time — not too much to incur high storage costs or risk obsolescence, and not too little to avoid stockouts and missed sales opportunities. Effective inventory management strikes a balance between these extremes, ensuring that resources are used wisely, and customer satisfaction is maintained. But if the DSIs are different, it doesn’t necessarily mean one company’s inventory management is any less efficient than the other. The variation could be because of differences in days in sales inventory supply chain operations, products sold, or customer buying behavior. Understanding the days sales of inventory is an important financial ratio for companies to use, regardless of business models. If a company sells more goods than it does services, days sales in inventory would be a primary indicator for investors and creditors to know and examine.
What’s the difference between DSI and inventory turnover?
Regular monitoring of DSI helps in identifying trends, addressing issues promptly, and aligning inventory management with changing market demands. As well, the management of a company will also be interested in the company’s days sales in inventory. Knowing these details will help gain insights into how efficiently inventory is moving.

Higher stock turns are favorable because they imply product marketability and reduced holding costs, such as rent, utilities, insurance, theft, and other costs of maintaining goods in inventory. Just take the number of days in a year and divide that by the inventory turnover. Finding the inventory turnover days doesn’t provide any new information, but framing it in terms of days is helpful for some. There are many reasons why a company may have a lower ITR than another company. Be sure you read a company’s financial statements and any notes to get a full picture.
When this happens, I usually go to Google to find a brand with the item in stock. AI uses machine learning to make predictions based on historical data. However, unlike Excel, machine learning can make predictions based on variables that might not be included in the historical data. Instead of spending the rest of the night searching for answers, I went straight to a reliable source. Recently, I sat down with Mark Zalzal, a senior data analyst, to better understand how to forecast inventory. Days Sales in Inventory (DSI) aka, Average Age of Inventory, demonstrates the time needed for an organization to turn its stock into deals.

By consistent demand, I mean that your products predictably move out of the warehouse without sitting on the shelves too long. Examples of these products might be everyday household commodities such as cleaning supplies or hand soap. As a small business owner, I’m bad about putting off tasks that need to be done as soon as possible.
Days Sales in Inventory (DSI)
Another important part of the DSI formula is the cost of goods sold (COGS). This number includes all the costs involved in making the products, like materials, the money spent on workers, and other expenses. COGS is crucial in the DSI calculation because it’s directly linked to the products that are sold.
To use this formula, you’ll divide your average inventory by your COGS, then multiply the result by 365—the number of days in a year. The product is how many days it would take to sell your average inventory. One of the biggest reasons for a high DSO is manual invoicing and slow payment collection.

For instance, retail stores and grocery chains typically have a much higher ITR. As a result, these businesses require far greater managerial diligence. Over-ordering or producing larger batches of a product than you can sell is a common culprit of a low inventory turnover ratio. While you never want to order so little product that your shelves are bare, it’s typically in your best interest to order conservatively, especially for a new product that you’ve never offered before. Secondly, when the maintenance cost, rent, security cost, and other expenses of holding inventory are not managed efficiently, it directly impacts your profit margin. Hence, DSI value helps you to study the movement of the goods in the supply chain.
It helps to know when certain products might become popular and how quickly you’ll sell through your stock. By purchasing the appropriate amount of inventory — no more than what you need — you can reduce the amount of money you’ll pay in storage and holding costs and stretch your budget just a bit farther. Zalzal told me demand planning and inventory forecasting are also especially important for companies that sell products with expiration dates. You don’t want to purchase an overabundance of a product with an expiration date only to have it expire while sitting on your warehouse shelves — talk about a loss in profit margins. One reason your company might struggle with low inventory is vendor delivery times. 72% of small and medium-sized businesses struggle with inconsistent delivery times, especially if they’re sourcing their inventory from vendors overseas.

December brought an optimistic end to the year, with consumer sentiment riding high and high-priced vehicles selling like hotcakes. As is common in the new year, consumers slow down; new-vehicle sales in January were down by 25% month over month. Weather disruptions and the general desire to focus on the year ahead leave more buyers on the sidelines, but sales are expected to pick up as tax refund season begins. Deskera Books enables you to manage your accounts and finances more effectively. Maintain sound accounting practices by automating accounting operations such as billing, invoicing, and payment processing. Conversely, a company in the manufacturing industry might experience a decrease in sales during economic downturns, which can decrease its DSI ratio.
A company with a low DSI ratio might be holding too much inventory, which can lead to increased holding costs and reduced profitability. The first step in calculating DSI ratio is to determine the average inventory level during the period for which you want to calculate the ratio. This is typically done by taking the sum of the beginning and ending inventory levels and dividing by two. The ratio is calculated by dividing the average inventory by the cost of goods sold and then multiplying the result by the number of days in the period being measured.
Trend Analysis (Time Series Forecasting)
As Zalzal told me, inventory forecasting is the foundation for demand forecasting. When you factor in supply, demand, other variables, and historical data and trends, you can make educated predictions about future sales and how quickly your inventory will dwindle. According to Mark, using AI when forecasting can help companies make better, more accurate predictions. The better your predictions are, the better your inventory management will be. Mark mentioned that you can do inventory forecasting manually using tools like Excel.
Managing inventory levels is vital for most businesses, and it is especially important for retail companies or those selling physical goods. Days sales in inventory (DSI) tells you the average number of days it would take to turn your average inventory into cash. An ideal DSI is typically between 30 and 60 days, though this will vary by industry and the size of the business.
