How to Reduce Stock Variance in Hospitality
Investigate unexplained stock differences without jumping to blame. Start with timing, deliveries, recipe units and the evidence behind each count.
What stock variance means
Stock variance is the difference between measured stock usage and expected usage. Its meaning depends on the report’s sign convention and treatment of recorded waste. A difference is an investigation prompt, not proof of theft, and there is no single acceptable percentage for every product or venue.
Check the period before checking the people
A delivery counted after the stocktake but booked before it can create an apparent shortage. Align opening and closing counts, physical receipts, sales trading dates and transfers. Confirm that an invoice and its linked delivery have not both been treated as separate purchases.
Normalise the units
Check bottle capacity, case size and serving measures. Compare liquid quantities in compatible volume units, food in compatible weight units and countable items as units. A 50ml cocktail measure cannot be interpreted as one bottle; grams cannot be treated as millilitres without a valid product-specific conversion.
Compare the saved recipe with the served drink
Confirm garnishes, side serves, batch yield and portions per till item. Use the venue’s actual recipe rather than assuming that a recognised cocktail name determines the ingredients. Review refunds and excluded sales so the expected usage is explainable.
Recount and assign a concrete next step
Prioritise discrepancies by value and operational context. Recount the relevant area, inspect the source documents and review waste records. Record the cause when supported by evidence, agree an action and compare the next period using the same definitions. A supplier credit is not recovered money until the supplier accepts it.
