Karu is built for operators who already know the maths but need the numbers to stay current when invoices, batches, and packaging keep moving.
Cost final recipes and sub-recipes together.
Keep supplier history tied to the ingredients that drive margin.
Review AI-created drafts before they affect official costs.
Example
Example: a garlic mayo base rises €0.40/kg on the latest invoice. Karu shows which sandwiches, bowls, and sides inherit the change before you approve the new supplier price.
Checklist
Upload one recent supplier invoice and one core recipe.
Confirm yield and packaging on the products you sell most.
Approve drafts before they touch official costs.
Review the first exposed menu items, then decide whether to correct the cost or adjust the price.
