Where Do Hidden Inventory Costs Come From?
Most people who work in warehouses know roughly what a product costs. They see the PO, they know the unit price, they've got a general sense of margin. But that number on the PO is not the price of the product. It's the starting point.
By the time a unit is received, putaway, counted, picked, replenished, maybe miscounted and recounted, and finally shipped — it has accumulated cost at every single step. Some of it is obvious. Labor per pick is usually tracked. Freight gets allocated. But a lot of it doesn't show up anywhere clean. The carrying cost on inventory that sat in a wrong slot for six weeks because a count was off. The labor burned on a recount after a shrinkage flag. The rush shipment to cover a stockout that happened because on-hand was wrong in the system. That's all price. It just doesn't live on the label.
I've seen operations where the landed cost of a $4 item ballooned past $6.50 by the time it shipped — not because of anything exotic, just accumulated handling errors, a receiving backlog that stretched putaway by three days, and a cycle count process that was manual, slow, and running about 90% accuracy on a good week. Nobody had added it up. When someone finally did, it changed what they were willing to pay to fix the count problem.
This is why inventory accuracy isn't an ops metric. It's a pricing input. If you don't know what's on hand, you don't know your true cost of goods, and everything downstream from that — your margin, your reorder decisions, your customer commitments — is built on a number that might be wrong.
There's no tidy fix here, but the first step is treating the count like it matters as much as the PO. Because it does.
