How to manage food costs when supplier prices are rising

Supplier prices rise. They always have. The question for any hospitality operator is not whether prices will increase, but whether they will know quickly enough, and specifically enough, to respond before the damage to margin is material.

Most operators know their food cost is under pressure. Fewer know precisely which products are driving it, which suppliers are increasing faster than others, and whether the pressure is being absorbed or is passing through to the GP figure.

The delay problem

The most common reason operators cannot respond to supplier price increases quickly is that the information arrives too late.

An invoice comes in with a higher price than the last one. It is processed by a manager who is focused on getting it into the system, not on benchmarking it against the previous price. It passes through to the accounts. Three weeks later, the period GP shows a deterioration. The investigation begins.

By the time the price increase is identified as the cause, the same higher-priced deliveries have arrived three or four more times. The opportunity to respond at the point of the first increase has passed.

The solution is not to look more carefully at invoices. It is to have a system that flags price changes automatically when an invoice is processed, before it is approved.

Understanding which costs are moving

Not all food costs move together. A period of rising costs typically affects specific categories — proteins, dairy, or imported goods — while others remain stable.

For the GP response to be effective, the analysis needs to go below the total food cost line. A restaurant with a food cost that has risen from 30% to 34% over six months needs to know whether this is driven by red meat, by a single problematic supplier, or by across-the-board increases that reflect market conditions.

Each of these has a different response.

A single supplier increasing faster than market rates is a purchasing conversation. Evidence of the rate differential is the basis for that conversation.

A single category rising because of genuine market conditions is a menu response: can the category be reduced, substituted, or repriced to protect margin? If you are also planning a menu change at the same time, factoring in current cost movements before finalising new dish prices is essential.

Across-the-board increases require a broader review of whether menu pricing can be adjusted, and by how much, without affecting volume.

None of these responses can be calibrated without category-level cost data, updated in real time as invoices are processed.

The invoice comparison is the early warning system

Every invoice processed through a system that stores pricing history can be compared against the last invoice from the same supplier for the same product.

This comparison is not complicated. The system knows what the product cost last time. It knows what it costs this time. The difference, expressed as a percentage, is the price movement.

If this comparison is surfaced at the point of invoice approval — before the cost is committed — the operator has a decision to make. Accept the new price, query it with the supplier, or substitute the product. They have this decision because they have the information.

If the comparison is not surfaced, the new price passes through silently and appears in the accounts as an unexplained cost increase weeks later.

What you can actually respond to

When you know which costs are rising, the range of responses is wider than it initially appears.

Supplier negotiation. If a specific supplier is increasing faster than others for the same product category, the price movement data provides the basis for a conversation. Not an anecdote, a number.

Product substitution. If a specific ingredient is rising rapidly, are there substitutes at lower price points? This is a kitchen conversation, but it needs to be informed by cost data. Which substitution options exist, and what does each one do to the GP of the affected dishes?

Menu engineering. Rising costs on high-volume items are a specific problem. If the dish that sells most frequently also has the fastest-rising ingredient cost, it has a disproportionate effect on overall food GP. Adjusting the specification, the portion, or the price of that dish has a larger impact than the same change applied to a low-volume item.

Waste reduction. When purchase costs rise, the cost of waste rises with them. A product wasted at £8 per kilo costs more than the same waste at £6. Tightening portion control and reducing prep waste becomes financially more significant when ingredient costs are high. There are practical steps you can take to reduce food waste systematically that pay off even more when ingredient prices are elevated.

What to avoid

Across-the-board menu price increases are the default response to rising costs, but they carry risk. Price-sensitive customers reduce visit frequency or order down. If the increase recovers cost on paper but reduces volume, the net effect on GP is negative.

The more targeted the response — addressing the specific categories and products where costs are rising, rather than applying a blanket change — the lower the risk of an unintended consequence. Looking at ways to improve profitability without raising prices alongside any repricing decision helps to identify which margin can be recovered operationally before passing costs to customers.

Hops flags price movements at the point of invoice approval, compares against prior invoices from the same supplier, and tracks category-level GP weekly. When food costs rise, the operators using Hops know which products are responsible and by how much — before the period accounts are closed.
