Purchasing & Inventory
The cost that leaks before the kitchen
By Noriva · 28 April 2026

Purchasing, receiving and storage decide a large part of food cost before a chef touches anything — and they are the least supervised part of most operations.
Kitchens receive a great deal of attention. The back door receives almost none. Yet by the time an ingredient reaches a station, its cost has already been set by what was ordered, at what price, whether the full quantity arrived, and how it was stored in between.
## Where the leaks are
**Ordering without a specification.** "A box of tomatoes" is not a specification. Grade, size, origin and pack size all move cost and yield, and without a written spec the supplier decides which one you receive.
**Ordering by habit.** Par levels set at opening and never revisited, adjusted upward after one busy week and never adjusted back.
**Receiving without checking.** Weight not verified, quantity not counted, quality not inspected, invoice not matched to the order. A short delivery accepted once becomes a short delivery every week.
**Price drift.** Supplier prices rise gradually and are noticed only when someone looks. Without a price list to check against, an increase is invisible until it shows up in food cost weeks later.
**Storage and rotation.** Poor rotation converts purchased stock into waste with no event to mark it, so it is attributed to the kitchen rather than to storage.
**Over-purchasing to be safe.** The most understandable and most expensive habit. Excess stock is cash converted into something perishable.
## Receiving is a control point, not a task
Receiving is usually given to whoever is available. That is a mistake, because it is the only moment where what you pay for and what you get can be compared.
A minimum standard: someone named is responsible; deliveries are checked against the order, not against the invoice; weights are verified for anything priced by weight; quality is inspected before signature; discrepancies are recorded and raised the same day.
None of this is complicated. It fails because it is nobody's specific job.
## Specifications protect both sides
A written purchase specification is not a hostile document. It tells the supplier exactly what you need, which makes it easier for them to supply consistently and harder for an inconsistent delivery to be a matter of opinion.
Specify by what matters to your product: grade, size, weight range, packaging, temperature on arrival, shelf life remaining. Then check against it. A spec nobody checks is a preference.
## Par levels are decisions, not settings
Par levels should follow the demand curve and the delivery schedule. A venue receiving three deliveries a week should not hold a week of stock, and one receiving weekly cannot run on two days.
Review them quarterly, and after any significant menu change. Items that left the menu often stay in the ordering routine for months.
## The supplier relationship
Cost is not only price. Reliability, consistency, delivery windows and the willingness to fix a problem all have a monetary value, and the cheapest supplier is frequently not the lowest cost once short deliveries and quality variation are counted.
Reviewing terms periodically is normal commercial practice, not an act of aggression. So is having a second source for the items you cannot operate without.
## Practical recommendations
1. Write specifications for your top twenty purchased items.
2. Name one person responsible for receiving on each shift.
3. Check deliveries against the order, not the invoice, and weigh anything priced by weight.
4. Keep a current price list and check invoices against it.
5. Review par levels quarterly and after every menu change.
6. Have a second source for anything the operation cannot run without.
7. Count stock consistently — the same way, the same day, the same person.
## In short
Most food cost work focuses on the kitchen, where the ingredient is already in the building and already paid for. A meaningful share of the leak happens earlier, in the least supervised part of the operation, and it is closed by written specifications and a receiving routine rather than by anything complicated.
