Shrinkage is inventory that disappears for reasons other than a sale: ingredients that spoiled, pieces that broke, units that walked off, and counts that were simply wrong. It shows up as the difference between what your records say you should have and what a physical count actually finds.
Every business has some shrinkage, and pretending it is zero quietly inflates your inventory valuation and understates your true costs. Tracking it — by posting adjustments for waste and reconciling counts during a stocktake — turns an invisible leak into a measured cost you can manage and, where it is a legitimate business loss, deduct.
Perishable and fragile makers feel shrinkage most: a baker's unsold loaves and a potter's kiln losses are shrinkage as surely as theft is. Watching the rate over time is an early warning that a process — storage, handling, or counting — needs attention.
