Sample counts that keep inventory accuracy honest

Full physical counts remain the gold standard, yet many Ho Chi Minh City warehouses run continuous inbound volume that makes a freeze impractical. Sample counts fill the gap only when the sample is boringly consistent.

Pick twenty locations each day from three bands: high-velocity pick faces, medium movers, and slow reserve. Rotate bands so no zone goes a full week without a touch. Record variance in units and in value; a single high-value miss matters more than twenty low-value ones for most finance reviews.

Publish a rolling thirty-day accuracy percentage next to the number of locations touched. Accuracy alone can look healthy while the sample shrinks. Warehouse performance monitoring should show both numbers on the same sheet.

If variance clusters in one zone for three consecutive days, pause the rotation and deepen the sample there before you change system settings or blame receiving.
