Nobody knows how much flour is left until it runs out
Ingredient stock lives in someone's memory or in a notebook updated when there is time. The shortfall shows up mid-bake, by which point it is too late to buy.
Ingredients come off when the product sells
Load a recipe per product and each sale draws down what it uses. Flour stock stops being a recollection and becomes a number.
- A recipe per product, with the quantities you actually use
- Low-stock alerts before an ingredient runs out
- Cost per piece worked out from what you paid for the ingredient
