Eight records behind a defensible margin decision
Calculators produce an answer from inputs. These records preserve where the inputs came from, which period they cover and what the result still cannot prove.
Operating record
Recipe cost version
Document the ingredient quantities, prices, yield assumptions and effective date behind one plate-cost calculation.
Operating record
Supplier price change
Preserve the old price, new price, unit, effective date and affected recipes before estimating margin impact.
Operating record
Waste event
Record what was discarded, why, in which unit and at what documented cost without treating one event as a trend.
Operating record
Inventory period
Define the beginning inventory, purchases, ending inventory and matching food-sales period behind actual food cost.
Operating record
Menu price scenario
Separate a proposed price from a live menu change and show the plate-cost, margin and volume assumptions behind it.
Operating record
Weekly contribution
Track item revenue, variable food cost and units sold over one defined week without calling contribution net profit.
Operating record
Menu mix snapshot
Freeze item popularity and contribution inputs for a comparable menu-engineering review.
Operating record
Break-even assumption set
Document fixed costs, variable-cost ratio, average check and period before calculating required sales or covers.
