Why Your Inventory Turns Stall, and What to Do About It
Inventory turnover is one of the most watched numbers in supply chain, and one of the most misread. The math is simple: cost of goods sold divided by average inventory over the same period. A higher ratio means you are selling and replenishing stock more often, freeing up cash and shelf space. In early 2022, with cash expensive and warehouses full of goods bought against shortage fears, the pressure to improve turns is real. The trouble is that most attempts to raise the number do it in ways that backfire.
The mistakes that keep turns low
Treating one number as the whole story. A single company-wide turns figure hides everything that matters. Fast movers and dead stock average out to a comfortable-looking ratio while a third of your shelves gather dust. Segment by SKU, by category, and by location before you decide anything.
Cutting safety stock to flatter the ratio. The fastest way to raise turns on paper is to slash inventory. Do it without understanding demand variability and lead-time risk and you trade a working-capital win for stockouts, expedited freight, and lost sales, which in 2022's volatile lead-time environment is an easy way to lose customers.
Ignoring lead time and its variability. Turns and lead time are linked. When suppliers became slower and less predictable, the inventory you must hold to keep service up rises. Chasing a turns target without renegotiating or de-risking supply just guarantees you fail one of the two.
Letting forecasts drift from reality. Stale forecasts overstock the items that already slowed and understock the ones that picked up. Inventory accumulates exactly where it sells least. Without a regular forecast-versus-actual review, turns erode quietly.
Buying in bulk for a unit-price discount. A purchasing team rewarded on unit cost will buy a year of a slow item to save a few percent, then wonder why working capital is locked up. Total cost, including the cash and space the stock consumes, is the number that counts.
Practical ways to actually improve turns
Real improvement comes from matching how you stock each item to how it actually behaves, not from a blanket target imposed from the top. Start with an ABC analysis so attention goes where the money is, then set service-level and stocking rules that fit each tier instead of treating a cheap fast-mover like a critical spare.
Segment inventory by value and movement (ABC), then set turns targets per segment, not one for all.
Right-size safety stock from real demand variability and lead-time data, not a flat number of weeks.
Attack the slow tail first: liquidate or write down dead stock so the live business is not subsidising it.
Shorten and stabilise lead times through supplier collaboration; a reliable lead time needs less buffer.
Review forecast accuracy on a cadence and feed corrections straight back into reorder points.
Done this way, higher turns are a by-product of a healthier operation rather than a target you squeeze the business to hit. You free up cash without sacrificing the service that keeps customers, which is exactly the balance the conditions of 2022 demanded. The number improves because the underlying decisions got sharper, and that improvement holds when the next disruption arrives.
