Costing

What a dish, a batch or a case actually costs you.

Pricing & margin

What to charge, and what a price change is worth.

Operations

Pars, variance, labour — the weekly numbers.

Menu & guests

Menu engineering, QR menus, and what guests actually see.

The same math the product runs.

Every tool here uses the formulas Marji applies to real menus — the margin math that recosts a dish the moment a supplier invoice lands. Type your numbers, read your answer. Nothing is emailed unless you ask for the full report.

Want the loop that runs it for you — invoice in, margins recalculated, the exact price fix named? See the demo dashboard on our sample bistro, or check pricing — there's a free forever QR menu tier, and paid plans start at $59 a location.

Not sure what a number means? The costing glossary defines every term with its formula and a worked example.

These calculators are one part of it — everything Marji gives away free is on one page, including the food cost index and the free QR menu.

The numbers behind the math.

Once a week: what moved on ten commodity series, what it does to a typical plate, and one thing worth repricing. No product pitch.
