ABC Analysis Inventory: The 80/20 Method to Cut Stock Costs [2026]

If you’re holding more than a few hundred SKUs, you have a focus problem. Every item demands the same checks — counts, reorders, supplier reviews, photo refreshes — but only a fraction of them actually moves the P&L. ABC analysis inventory is the simplest tool in inventory management for fixing that focus problem. You sort SKUs into three tiers based on annual revenue contribution, then apply different policies to each tier: tighter controls and frequent counts on the few high-value items, lighter touches on the long tail.
