Frequently Asked Questions
What is bar inventory shrinkage?
Shrinkage is the difference between the liquor your inventory records show as used and what your POS sales data says should have been used, often due to over-pouring, spillage, comps, or theft.
What's a normal shrinkage percentage for a bar?
Most well-run bars target shrinkage under 5-8%. Higher rates suggest issues with pour control, waste tracking, or theft.
How often should I calculate shrinkage?
Weekly or monthly inventory counts are common, allowing you to catch and address issues before they compound.
