Stock takes and waste in a restaurant: finding the gap in usage
A restaurant seldom loses money in one big hit. It slips away a pour or a portion at a time. The difference between what your sales and recipe cards say should have been used and what really left the shelves is called variance, and this guide explains how to find it.
Keeping stock under control (short answer)
- Enter each delivery with its quantity, price and batch on the day it comes in.
- Give every dish its own recipe card with quantities, so each sale maps to what it uses.
- Record losses on their own lines: write-offs, breakages, expired items, cancelled orders and staff meals.
- Count area by area on different rhythms: the bar weekly, perishables twice a week and the dry store monthly.
- Each month, set actual usage against theoretical usage and look into any variance over a limit you choose, for example 3%.
Theoretical usage against actual usage
Actual usage = opening stock + deliveries received − closing stock.
Theoretical usage is the amount your sales should have consumed according to the recipe cards. What separates the two figures is the variance, a loss that nobody notices.
Bar example with gin: the month starts with 10 bottles of 0.7 L (7.0 L), 8 more bottles (5.6 L) arrive, and 6 full bottles plus 0.4 L (4.6 L) remain at the end. Actual usage is 7.0 + 5.6 − 4.6 = 8.0 L.
Now count the serves sold: 150 serves of 50 ml make 7.5 L of theoretical usage. The variance is 0.5 L, which is 10 serves missing. At an illustrative €4.50 per serve, that is €45.00 on a single product.
Table: kinds of loss and where to record each
Losses in a restaurant, each with an example and the place it is recorded
| Type of loss | Concrete example | Where it is recorded |
|---|---|---|
| Technical loss | Peeling vegetables, trimming meat | On the recipe card, as the yield measured in your kitchen |
| Expiry | Dairy left unused past its use-by date | A waste entry in the app that states the reason and the quantity |
| Breakage and damage | A bottle that falls at the bar | A waste entry in the app that states the reason |
| Cancelled or returned order | A plate returned to the kitchen | The cancellation reason, written into the venue's own records |
| Staff meal | The team's meal before service opens | Internal consumption, logged as waste with a reason |
| Guest comps | A dessert given free after a complaint | Promotional use, noted together with its reason |
Table: how often to count stock
Counting frequency by area, for a restaurant with a kitchen and a bar
| Area | Frequency | Why |
|---|---|---|
| Bar (spirits, drinks) | Weekly | Each unit is worth a lot and variance runs high |
| Perishables (meat, fish, dairy) | Twice a week | Items spoil quickly and orders can go wrong |
| Dry store (flour, pasta, canned goods) | Monthly | Items turn over slowly and losses are rare |
| Full inventory, valued | Monthly, plus a valuation at year end | It underpins the month's result and the year-end figure your accounts need |
Rules to check where you operate
- Check whether your accounts call for a stock valuation at period end, and agree the method with your accountant.
- Check whether you must be able to show which supplier each delivered batch came from, and keep the records that prove it.
- Find out which food-safety management records you are expected to keep, such as temperature logs and use-by dates.
- FEFO (first expired, first out) is a handy way to keep stock inside its use-by dates.
- Check how digital record-keeping for tax is expected to work where you operate, and keep purchase invoices in a system that supports it.
Common mistakes
- Counting the bar only monthly, so that by the time a variance appears, a month of evidence has vanished.
- Skipping staff meals, which then show up as a loss nobody can explain.
- Treating open bottles as either full or empty instead of estimating what remains in them.
- Signing for deliveries unchecked, then discovering a shortfall for goods that never arrived.
- Comparing only the overall stock value rather than usage per product, which lets an 8% variance on one item vanish in the average.
How 4restaurants.net helps
- Ingredient stock levels live in the same application as your recipe cards and orders.
- Every dish carries its own recipe card, and the reports by dish show what was sold.
- For a chosen period, the food-cost report presents theoretical cost, waste, shrinkage found at stock counts and the variance.
- A low-stock list and draft supplier orders help you decide what to buy next.
- Stock is taken off when a bill is paid in full, so the food-cost report can show how theoretical and actual usage differ.
