Use the fee base
Confirm whether commission applies to the item subtotal, delivery charge, or another amount.
Include channel packaging
Delivery containers, seals, bags, and cutlery may differ from dine-in costs.
Compare contribution
Compare the currency amount retained per order, not only the food-cost percentage.
Use your own operating data
Supplier prices, yields, labor rates, and channel fees change. KitchenMargin treats them as editable inputs rather than universal facts.
