Identifying Low-Rotation Products: Stop Investing in What Does Not Sell

The warehouse manager calculates that 35% of available space is occupied by product that has had no movement for over 90 days. Some SKUs have not had a single outgoing transaction in the past semester. The purchasing area continued restocking them during that period because the system does not distinguish between high and low rotation, and the reorder criterion is applied uniformly across the entire catalog. At the same time, three high-demand products are running out of stock before the next purchase order arrives, generating lost sales that nobody counts as such. The company is investing capital in inventory that does not move, while losing sales from lack of inventory in the products that do move. Both problems have the same root: lack of visibility into the real rotation of each SKU.

Identifying Low-Rotation Products: Stop Investing in What Does Not Sell

Low-rotation products freeze capital, generate growing storage costs and distort purchasing decisions. Identifying them with precise rotation and coverage data allows capital to be freed, warehouse space to be optimized, and investment to be concentrated in the inventory that generates real cash flow.

The Immobilized Capital Nobody Sees on the Balance Sheet: The Cost of Non-Rotating Inventory

From an accounting perspective, inventory is an asset. But from an operational and financial perspective, inventory that does not rotate is a form of immobilized capital that continuously generates costs without producing returns. Those costs include the physical space it occupies, the insurance that covers it, the risk of deterioration or obsolescence and, above all, the opportunity cost of money tied up in merchandise that does not generate cash flow. A company with inventory oversized by 20% above its optimal level may be immobilizing the equivalent of several months of operations in product that does not contribute to period revenue.

Inventory Turnover Index: The Metric That Separates Productive Inventory from Dead Inventory

The inventory turnover index measures how many times a SKU's inventory is sold and replenished in a given period. A high index indicates the product flows quickly and capital returns rapidly to the company as cash. A low index indicates merchandise accumulation, higher risk of deterioration or expiration, and immobilized capital. The basic formula is simple: cost of sales for the period divided by average inventory for the same period. But its real value lies in the comparison between SKUs within the same catalog: it identifies exactly which products generate cash flow and which are consuming space and capital without contributing to results.

Without a system that automatically calculates and updates this indicator by SKU, that comparison requires hours of spreadsheet work with data that, by the time it is analyzed, is already weeks old.

Why the Purchasing System Reproduces the Problem When It Has No Rotation Visibility

The problem of low-rotation inventory rarely originates in an isolated poor purchasing decision: it originates in a replenishment system that applies the same criteria to all SKUs without distinguishing between those that sell every day and those that have had no outgoing movement in months. When the reorder point is calculated based on the catalog's historical average coverage, low-rotation products are restocked with the same regularity as high-rotation ones, accumulating stock that the market no longer demands at the same rate as before.

The Drag Effect: How Slow Inventory Contaminates Decisions Throughout the Chain

Low-rotation inventory creates a drag effect that affects the entire decision chain. By occupying warehouse space, it forces the company to manage suboptimal locations for high-demand products, increasing picking times and degrading service levels. By appearing on the balance sheet as an asset, it can create a perception of solvency that does not reflect the business's real liquidity.

At Oasys, our inventory analysis module calculates the rotation index, coverage days and opportunity cost of immobilized capital by SKU in real time, enabling purchasing and management teams to make differentiated decisions based on each product's actual behavior.

How to Act on Low-Rotation Products: Four Decisions That Require Precise Data

Once low-rotation products are identified with precise data, the company faces four types of decision. The first is replenishment policy: if a SKU has low rotation but is strategic for certain customers, the target coverage should be different from that of a high-demand product. The second is the liquidation decision: if the product has no prospect of recovering its historical rotation, the cost of maintaining it in the catalog exceeds the marginal revenue it generates. The third is the discontinuation decision: when a SKU has had zero rotation for several periods and does not respond to commercial actions, keeping it in the catalog generates costs without operational justification. The fourth is space reallocation: space freed by actively managing slow inventory can be redirected to the highest-demand products, improving picking times and customer service levels.

Frequently Asked Questions

How does Oasys define what constitutes a low-rotation product within the system?

In our platform, rotation thresholds are configured by product family or by criteria the client defines according to their industry and business model. A food distribution product with 30 days without movement may be considered low rotation, while an industrial spare part with the same period may be completely normal. The system calculates the rotation index, coverage days and opportunity cost by SKU with the parameters the company establishes, and generates automatic alerts when a product crosses the defined threshold.

How much capital can a company free up by actively managing its low-rotation inventory?

The capital release potential depends on the weight that low-rotation products carry in total inventory. In distributors with broad catalogs, we have identified that between 20% and 35% of inventory value can be concentrated in SKUs with very low or zero rotation. Actively managing that segment -- through differentiated replenishment policies, liquidation or discontinuation -- can free between 10% and 20% of working capital immobilized in inventory over a 6 to 12 month cycle.
