Restaurant stocktaking. How to explain stock discrepancies
Does your POS stock differ from the physical count? Learn how to reconcile usage, check recipes and deliveries, and investigate unexplained differences.
A stock difference is a question, not a verdict
The system shows twelve kilograms, but the fridge contains nine. It is tempting to blame portioning, missing records or theft. The discrepancy alone does not identify the cause.
First check that you are comparing the same products, units and points in time. I follow the product from delivery through preparation to service. A counting error or incorrect recipe can resemble unrecorded consumption.
Counting is only the start
A physical count establishes what is actually present. Comparing it with the records identifies differences to investigate. Adjusting the system balance does not resolve their cause.
Keep the discrepancy report before making corrections and record your findings. This guide concerns operational stock control in kitchens and bars; it does not replace inventory and documentation requirements agreed with your accountant.
Prepare a reliable count
Agree the exact time and locations covered. Count outside service where possible. If movements cannot stop, record every receipt and issue during the count so it can be assigned to the correct point in time.
Include stores, fridges, freezers, the kitchen and bar. Moving a product to a kitchen station does not necessarily mean it has been consumed. Check that all relevant delivery documents have been entered.
- Use consistent product records, units and pack conversions.
- Check scales and deduct container weight.
- Allocate counting and verification responsibilities.
- Record physical quantities rather than copying expected balances.
Use a consistent method for open packs and prepared products
Weigh or measure open packs in the agreed unit. For open bottles, weighing requires a suitable conversion for the specific product and bottle. Gross bottle weight is not the volume of liquid.
For sauces, stocks and other prepared products, establish how production is recorded. If ingredients have already been issued into a prepared product, do not count them again separately. If the system still holds them as ingredients, agree a reliable equivalent calculation.
Changing the counting method between periods can create an apparent movement that does not reflect actual usage.
A fictional example: three kilograms unexplained
This example covers one product, one period and the whole restaurant. It assumes no returns, transfers outside the venue or prepared stock requiring separate conversion.
The difference calls for investigation. It is not proof of theft or an automatic recoverable saving.
Opening stock: 10 kg. Receipts: 20 kg. Closing stock: 8 kg.
Reconciled usage: 10 + 20 − 8 = 22 kg.
Sales-based recipe usage: 18 kg, including standard yield.
Recorded non-sales issues: 1 kg.
Unexplained difference: 22 − 18 − 1 = 3 kg.
At an assumed PLN 30 net/kg, the difference is valued at PLN 90.
Investigate causes you can verify
Recount first, then check documents. Compare system recipes with actual preparation, including portion sizes, units, substitutions and yields.
Review deliveries: were products weighed, and did quantities match the order and document? Was a more expensive substitute agreed? Price changes affect cost value but cannot by themselves explain missing kilograms.
Trace staff meals, owner consumption, tastings, remakes, spoilage and mistakes. Each needs a defined recording method. Do not deduct waste separately when it is already included in the recipe yield.
A restaurant audit in Wrocław
During an audit at a restaurant by Wrocław’s Market Square in May 2025, staff meals and owner consumption were not consistently recorded. Products were used without a clear record of their purpose.
The restaurant introduced recording all such kitchen and bar issues in the POS and closing the bills to the appropriate system accounts. Unannounced spot stocktakes also helped. Engaging kitchen staff in accurately recording the dishes issued was a particular difficulty.
Deliveries were being accepted without adequate checking or weighing. The audit recommended checking quantities, items and prices against orders, with advance notice of shortages. Delivery controls are described here as recommendations, and no unverified financial savings are claimed.
Set frequency and ownership
Match operational counting frequency to turnover, product value and error risk. A full month-end count can support monthly cost analysis. High-value products or recurring discrepancies may need more frequent checks.
Spot checks help narrow the time window but do not replace a full reconciliation. An unannounced date should not mean unclear rules or public accusations.
The owner or manager sets the process and reviews results. Kitchen and bar teams count and record issues. The person maintaining stock records checks documents and product records. Significant discrepancies should be verified by someone other than the original counter.
Turn the report into an action
Prioritise discrepancies by value, recurrence and importance. For each major issue, agree a hypothesis to test, an owner and a review date. Changing everything at once makes it hard to identify what worked.
If portioning is suspect, weigh portions and check the recipe. If staff meal records are missing, review the recording process. Return to comparable data after an agreed period.
There is no single discrepancy percentage that proves every restaurant is under control. Measurement variation, standard preparation losses and undocumented issues need to be distinguished.
A manager’s checklist
Before approving the reconciliation, check:
- Do dates and documents use the same cut-off points?
- Have all storage areas and prepared products been included correctly?
- Are units, conversions and recipes current?
- Are receipts, returns and non-sales issues recorded?
- Have significant differences been recounted?
- Does each major discrepancy have a next action, an owner and a review date?
Connect stock control to business performance
Reliable stock reconciliation supports ingredient cost analysis. Sales, labour costs and work organisation also influence performance, so stock should not be treated as an isolated list of shortages.
How I can help
At Hospitality Pro, within the agreed audit scope, I compare records with what happens during receiving, preparation and service. Reports and observation help distinguish recording or costing problems from operational issues and actual consumption.
The aim is a control process the team can use daily, with findings translated into actions and follow-up measurement.
