What is inventory accuracy?

Inventory accuracy answers the only question that determines whether the rest of your system is useful: when the record says 14 units in bin C-3, are there 14 units in bin C-3? Measured across a sample of SKU-location records, accuracy is the percentage that match within tolerance. How you count "match" matters. Absolute unit accuracy (52 recorded, 52 found) is the strict version. Many operations use a tolerance band, counting a record accurate if it's within 2% or within a small unit threshold, because chasing single-unit variances on bulk fasteners costs more than it returns. Pick the convention deliberately and keep it consistent, or the trend line means nothing. Benchmarks: well-run warehouses with scanning and cycle counts hold 95% to 99%. Spreadsheet-run operations typically sit at 80% to 90%, which sounds passable until you translate it: one record in six is wrong, so one pick in six starts with a surprise. Where teams trip: measuring accuracy only at the annual count, which yields one stale data point a year. Cycle counting turns accuracy into a weekly metric you can put on a wall, trend by zone and by counter, and tie to causes. Accuracy isn't the goal by itself; it's the precondition for trusting reorder points, promising stock to customers, and closing the books without a write-off fight.
