When margins slip in a food business, owners usually look at sales first, then at labor and rent. The supply chain is often the last place they look, because the losses there are spread across hundreds of small purchases, deliveries and write-offs. No single one looks serious. Together they can quietly take a large share of the profit.
These three questions are the fastest way we know to find out whether your supply chain is leaking margin.
1. Do you know your true food cost, by outlet, every week?
Many restaurant groups know their food cost as one monthly percentage for the whole business. That number hides the outlet that is over-portioning, the kitchen that is wasting prep, and the menu item whose ingredient prices went up three months ago without anyone repricing it.
What good looks like: actual food cost compared with theoretical food cost (what the recipes say it should be), for every outlet, every week. The gap between the two is your leak, and it tells you where to look.
How to start: cost your top-selling items from up-to-date recipe cards and supplier prices, run a weekly stock count of high-value ingredients in each outlet, and compare actual usage with what the sales say you should have used.
2. When did you last renegotiate terms with your top ten suppliers?
In most food businesses a small number of suppliers account for most of the spend. Terms agreed when the business had three outlets are rarely the right terms when it has fifteen. Prices drift, delivery schedules stop fitting the operation, and payment terms, rebates and quality standards are never revisited.
What good looks like: a clear view of spend by supplier and category, written terms for every major supplier, and a review of the top ten at least once a year, covering price, quality specifications, delivery, payment terms and volume rebates.
How to start: list your top ten suppliers by annual spend, check what was actually agreed with each one, and compare invoices against those terms for a few months. The differences are often a surprise.
3. How much of what you buy ends up as waste?
Every kilo thrown away was paid for twice: once when it was bought, and again in the labor and energy spent storing and preparing it. Waste comes from over-ordering, poor rotation, broken cold chains, over-production in the kitchen and products that expire on the shelf.
What good looks like: every write-off recorded with a reason, reviewed weekly by outlet, with orders based on forecast sales rather than habit, and storage and rotation routines that every shift follows.
How to start: for two weeks, log every item thrown away in two or three outlets, with the reason. The pattern that comes out of that log usually points straight at the fix.
Why these leaks go unnoticed
None of these problems shows up as one big loss. They show up as a food cost that is "a bit high", a supplier who is "usually fine", and waste that is "normal for the business". Fixing them is less about new software and more about ownership and routine: someone who owns the number, a weekly rhythm of review, and teams who understand that every gram counts.
