Build comparable periods
The sales, inventory, and recipe-cost windows must cover the same dates.
Measure the gap
Show variance in currency and percentage points. A gap is a diagnostic signal, not proof of theft or waste.
Investigate systematically
Check purchase prices, yields, portion standards, waste logs, transfers, comps, and inventory counts.
Use your own operating data
Supplier prices, yields, labor rates, and channel fees change. KitchenMargin treats them as editable inputs rather than universal facts.
