5 Warehouse Metrics Every SMB Must Track
Why warehouse metrics matter more than marketing hype
Many SMB owners pour budget into advertising, but the real bottleneck often hides in how they handle inventory. If you’re still using Excel or WhatsApp to track stock, you’ll feel the growth ceiling fast.
1. Inventory Turnover
This metric tells you how many times you refresh your stock in a given period. A low number means you’re holding dead inventory, which adds storage costs and the risk of obsolescence.
- Formula: Cost of goods sold ÷ Average inventory.
- Action: Spot low‑turn items and either reduce purchases or run promotions to move them.
2. Inventory Accuracy
If the gap between what’s recorded and what’s actually on the floor exceeds 5 %, every mistake translates into a missed sale or an over‑purchase.
- Formula: (Recorded inventory – Physical count) ÷ Recorded inventory × 100.
- Action: Implement cycle counts and barcode scanning to cut manual entry errors.
3. Order Cycle Time
From the moment a customer places an order to the moment they receive it, every minute counts. Long cycles breed dissatisfaction and increase support workload.
- Formula: Total processing time ÷ Number of orders.
- Action: Automate pick assignment and use real‑time alerts to flag bottlenecks.
4. Storage Cost per Unit
This indicator reveals how much you pay to keep each item in the warehouse. If the cost exceeds your profit margin, you’re losing money on every sale.
- Formula: Total storage costs ÷ Number of units stored.
- Action: Re‑layout the floor, apply cross‑docking, or outsource low‑turn stock.
5. On‑time Delivery Rate
Customers expect their orders when promised. A low rate hurts reputation and reduces repeat purchases.
- Formula: Orders delivered on time ÷ Total orders × 100.
- Action: Integrate your warehouse management system with shipping carriers for synchronized dates and notifications.
