Trimming at 50 % doubles the cost — it does not add half. A case price compared with a kilo price compares nothing. A month spent restocking the cellar looks catastrophic and the next one excellent, without a single dish having changed.
Each of these mistakes produces a perfectly plausible number. That is why nobody catches them — and that is where Margéo works, from the purchase price through to the P&L.

The median net margin
in commercial catering. At that level, a 2 % leak in food cost wipes out a third of the result.

What 50 % trim really costs
Cost divides by yield — it does not go up by half. Most recipe cards apply the wrong operation.
+15 %
An invisible price rise
Switching from 2 × 5 kg to 4 × 2 kg lets a supplier raise the price 15 % while appearing to lower it. Without unit conversion, nobody sees it.
The method
None of the three shows up on a bank statement or in a set of accounts. They blend into breakage, the season, or “a tough month”.
A fillet trimmed at 50 % costs twice as much, not half as much again. The dish looks profitable when it isn't, and the error produces a perfectly plausible number.
Cost divides by yield; it is never multiplied by the loss. Across three levels — ingredient, prep, dish. Automated tests verify it, precisely because a mistake here is invisible.
€22/kg · 35 % trim
€33.85/kg
A case price compared with a kilo price means nothing. A supplier who changes format can raise the price while appearing to lower it.
Every line is brought back to its base unit — 12 bottles of 0.75 L make 9 litres, a 2 × 5 kg makes 10 kg. It is the only way to compare two prices, and therefore to see a rise.
“2X5KG” → 10 kg
€4.20/kg
Two cases invoiced, one delivered. The gap shows neither in stock — there is nothing to count — nor in the month's margin, where it blends into breakage.
Margéo reads your delivery notes, finds the matching invoice and prices the gap in euros at the invoiced price — the only one you can hold the supplier to.

In practice
The rest calculates itself. You never re-enter what the invoice already says.
Or let suppliers send them straight to your drop address. The AI reads the lines, converts the units and updates your purchase prices.
Ten seconds after service. Your till sales import from the file your system already exports.
Cost per dish, delivery gaps, P&L, thirteen-week cash flow. Plus a purchase ledger ready for your accountant.
The platform
From purchase price to operating result, in one place.
Photograph them, or let suppliers deposit them directly. Lines extracted, units converted, the cost of every dish updated.
Delivered against invoiced, line by line. Above €5 of difference you get an email — below that, it's rounding.
Every dish in green, amber or red, with a suggested price. Ranked by euros lost per month, never by percentage.
Revenue, food cost actually used, payroll, overheads. Your monthly result, and a printable version for your accountant.
Balance, supplier due dates on their real terms, week-by-week projection. Margin and cash do not say the same thing.
Stock as a sum of movements, suggested price by bottle and by glass, sliding markup — because a flat markup doesn't sell.

Why Margéo
“The copilot doesn't fly for you. It watches the dials while you hold the stick.”
A restaurateur knows the trade better than any software. What's missing isn't advice — it's time, and somewhere the numbers are right without having to be re-entered.
Margéo grew out of that: existing tools ask for data entry and return averages. We wanted the opposite — that the invoice photographed in the evening is enough, and that the number returned is exact down to the trim, because an approximation on food cost produces a number that is perfectly credible and perfectly wrong.
That is why the quietest formulas — yield after trim, pack-size conversion, usage rather than purchases — are covered by automated tests. A mistake there would be invisible to the eye.
