In 2026, most operations buy the way they have always bought. The reorder list runs on a fixed reorder point plus a fixed quantity per SKU. Nobody looks at whether the SKU actually earned its shelf space last quarter. Fast movers reorder on time. Slow movers also reorder on time, even when the existing stock has been sitting at the back of the warehouse for a year. The reorder system works flawlessly at making sure the inventory keeps growing.

The cost is working capital tied up in dead inventory. A 9,400-SKU catalog can carry millions in stock where the slowest 20% has not moved in over 12 months. That cash cannot pay vendors. It cannot fund growth. It cannot earn a return. Meanwhile the fast movers occasionally stock out because the safety stock formula treats them the same as the slow movers, plus the team scrambles to reorder under pressure. Procurement spends its time fighting fires that better data would have prevented.

Inventory Turnover Reporting fixes the data side of the problem. The turnover ratio (cost of goods sold divided by average inventory value) calculates automatically for every SKU, category, plus location. High-turn winners surface immediately on the dashboard. Stagnant stock that has not moved in the configured threshold flags for review. The purchasing director gets a ranked list of candidates to discontinue, reduce, or relocate. CFOs receive a working-capital impact estimate for each decision. Reorder rules plus safety stock levels then get tuned against actual movement.

Turnover ratio math depends on the cost of goods sold plus the average inventory value, both expressed in money. The choice of valuation method changes the value side of that equation. A business running standard costing assigns a fixed unit cost per SKU set quarterly or annually. A business running real-time valuation uses FIFO, LIFO, or Weighted Average from Stock Valuation as the live unit cost. Turnover reporting reads either source automatically based on what the controller has configured for each SKU.

The same engine handles mixed environments. Some SKUs may run standard costing for budgeting purposes while raw material commodities run real-time Weighted Average to track market shifts. The turnover report respects each SKU's cost method when calculating the ratio. The output is a single comparable turnover metric across the catalog even when different SKUs use different costing approaches underneath. Purchasing plus finance see one ranked list rather than two parallel views that need reconciling at quarter-end.

Visualization makes the analysis actionable. Bar charts rank SKUs or categories by turnover. Trendlines show how turnover for a specific item has shifted over the last 12 months. Filters cut the view by vendor (which vendor's products move fastest), by warehouse (which site is sitting on dead stock), by classification (where slow-moving inventory concentrates by category), or by movement type. The result is a quarterly review meeting where everyone is looking at the same data plus the same chart, not arguing about whose spreadsheet is right.
