You know your selling price. But do you really know your margin?
On your production, your jobs or your hours.
You bring your experience: your unit prices, your output, the way you work. We give you the tool that works out the reality of your costs in 2 minutes, with the rates for your country, your trade, your place of work and your own business figures.
The real problem
Your costs move. Does your price?
Diesel, electricity, flour, steel: your purchase prices change without warning. And your selling price — when did you last set it?
Fuel
Every fill-up weighs on every job and every delivery.
Energy
Oven, workshop, office: the electricity bill is spread over every hour.
Materials
Flour, timber, steel, tiles: yesterday's purchase price isn't today's.
Your hour
Wages, social charges, unbilled time: your hour costs more than you think.
Recalculate your price in 2 minutes, with today's figures.

Its rules
- It asks one question at a time, in the language of your trade.
- It never makes up a figure: VAT, tax, social charges, output and purchase prices are yours to give.
- It doesn't calculate by itself: the engine calculates, the assistant copies out its results.
- You can open its calculation in the full calculation, change it and save it.
The assistant uses your Claude account: your first question will ask for your consent.
