Stock accuracy is a quality problem wearing a warehouse hat
Generic inventory tools count things. In a substance business the count is the least interesting attribute. What matters is which lot, whether it's released, when it expires, what it can be stored next to, and which finished batches it ended up inside. Get those wrong and the consequence isn't a stock discrepancy, it's a recall you can't scope.
That's why inventory in this sector belongs next to quality and production rather than next to finance. The moment stock status and quality status live in different systems, someone is allocating material that quality hasn't released.
