Buying is the least glamorous part of running a food business and one of the most reliable places to find margin. Unlike a price increase, better buying does not require the customer to accept anything, and unlike a menu change, it does not require the kitchen to learn anything new.

Most operators are not being overcharged in an obvious way. They are losing a percentage point or two through a set of small habits that nobody has revisited since opening. These are the seven that come up most often.

1. Never tendering the categories where the money actually is

Many kitchens are still buying from the suppliers they started with, at terms that were agreed when volumes were much smaller. Take your last twelve months of purchases, sort by spend, and look at the top four or five categories. Those are the ones worth a proper specification and a tender. The long tail can wait.

2. Comparing price per carton instead of price per usable kilogram

A cheaper case is not a cheaper ingredient if the yield is worse, the trim is heavier, or the product spoils faster. The only fair comparison is the cost of what actually reaches the plate. This is where a lot of apparent savings quietly reverse.

3. Buying without a written specification

If you have not documented the grade, size, packing, and origin you expect, you have no basis for a like for like quote and no basis for rejecting a delivery. A specification also protects you when the person who does the ordering changes.

4. Letting the kitchen and the office work from different prices

The chef orders against remembered prices. The office pays against invoices. The costing sheet uses whatever was entered last year. When those three do not match, nobody notices a supplier increase until it has been running for months.

5. Accepting substitutions at the door

A busy delivery window is the worst moment to make a purchasing decision. If a substitute arrives, someone should be checking that it matches the specification and that it is charged at the agreed price, not just signing for it because service starts in an hour.

6. Paying for delivery frequency you do not need

Daily delivery on items that keep perfectly well for a week costs money, either directly through minimum order charges or indirectly through the labour of receiving and checking. Match the delivery schedule to how the product is actually used and stored.

7. Negotiating once and never checking

This is the one that undoes all the others. Prices get agreed, then drift back over the following months through small increases that are individually unremarkable. Unless someone tracks the agreed price against the invoiced price, the saving quietly disappears and the exercise has to be repeated from scratch.

Where to start

If you only do one thing, do the spend analysis. Sorting twelve months of purchases by category tells you where the money is, and it usually contradicts what people assume. Operators frequently find that a category they never think about is a larger line than one they negotiate every year.

Salt and Ledger handles supplier sourcing and procurement for operators whose buying has never been properly tendered. That includes specification and tender across the main spend categories, negotiation of terms, a buying list your team can actually use, and savings tracked for six months so the gains do not quietly reverse.
