Stock takes and waste in a UK restaurant: finding the gap in usage
In a restaurant, money leaks away a measure or a portion at a time. The gap between what sales and recipe cards say you should have used and what you actually used is the variance. This guide shows how to find it.
How to keep stock under control (short answer)
- Record every goods receipt with its quantity, price and batch, on the day it arrives.
- Keep a recipe card with weights for every dish.
- Log waste separately: write-offs, breakages, expiry, cancelled orders and staff meals.
- Count each area at its own frequency: bar weekly, perishables twice a week, dry store monthly.
- Compare actual and theoretical usage each month, and investigate variances above your threshold, such as 3%.
Theoretical versus actual usage
Actual usage = opening stock + purchases − closing stock.
Theoretical usage is what sales should have used, from the recipe cards. The gap is the variance, the loss nobody sees.
Worked example at the bar: 12 bottles of 70 cl whisky (8.4 L) at the start, 6 more (4.2 L) received, and 5 full bottles plus 0.3 L (3.8 L) left. Actual usage is 8.4 + 4.2 − 3.8 = 8.8 L.
168 serves of 50 ml is 8.4 L theoretical, so 0.4 L, or 8 serves, is lost. At an illustrative £4.00 a serve, that is £32.00 on one product.
Table: types of waste and where to record them
Restaurant losses, with a concrete example and where each is recorded
| Type of loss | Concrete example | Where it is recorded |
|---|---|---|
| Technical loss | Trimming meat, cleaning vegetables | On the recipe card, as a yield measured in your kitchen |
| Expiry | Dairy kept past its use-by date | A write-off note, with batch and quantity |
| Breakage and damage | A bottle dropped behind the bar | A write-off note, at purchase cost |
| Cancelled or returned order | A dish sent back to the kitchen | The reason for the cancellation, noted in the venue's records |
| Staff meal | The team's lunch before opening | Internal use, kept apart from sales |
| Guest comps | A dessert offered after a complaint | Promotional use, approved by the manager |
Table: how often to count inventory
How often to count stock by area, in a restaurant with a kitchen and a bar
| Area | Frequency | Why |
|---|---|---|
| Bar (spirits, drinks) | Weekly | High value per unit and high variance |
| Perishables (meat, fish, dairy) | Twice a week | Risk of waste and of ordering errors |
| Dry store (flour, pasta, tins) | Monthly | Slow turnover, few losses |
| Full inventory, valued | Monthly, plus a year-end valuation | The basis of the month's gross profit, and the year-end figure your accounts need |
What UK rules say
- Stock is valued at year end for your accounts; check the method with your accountant.
- Traceability rules (retained from EU Regulation 178/2002) require you to know where each batch came from.
- HACCP-based procedures require records of temperatures and use-by dates.
- FEFO (first expired, first out) keeps stock within use-by dates.
- Keep purchase invoices with your VAT records, held digitally under Making Tax Digital if you are VAT-registered.
Common mistakes
- Counting the bar once a month: by the time variance shows, 30 days of evidence are gone.
- Not logging staff meals, so they appear as unexplained loss.
- Counting open bottles as full or empty, rather than estimating what is left.
- Accepting deliveries without checking them, then finding a shortfall that was never delivered.
- Comparing total stock value, not usage per product, so an 8% variance on one line disappears.
How 4restaurants.net helps
- Stock levels sit in the same application as the recipe cards and orders.
- Every dish has its recipe card, and the reports by dish show what sold.
- Reports by day, dish and waiter let you compare sales with what left the stock.
- Stock levels per ingredient help you decide what still needs ordering.
- Ingredient stock is counted against the recipes that use it, so the variance is visible for each dish.
