Add/Modify Inventory Items in a Family Group

In this window you set how an ingredient is used in a family group: the name it appears under, the quantity used, and how much is charged when it is added or deducted when it is removed.
How to get here: menu Items → Family Groups, Inventory Items button and, on that screen, Add or Modify (Inventory Items of Family Group).
The guide Adding an extra ingredient explains the whole process step by step with an example.
Ingredient data
Name: PizzaGest suggests the description of the inventory item, but you can change it for a more suitable one.
Grouping: the inventory items grouping it belongs to.
Quantity: the quantity of the ingredient that is used.
Kitchen Order: the layer in which the ingredient is added when the product is prepared. It sorts the ingredients on the kitchen chit.
Screen Order: the position in which the ingredient appears when you place an order.
Calories: they are calculated automatically from the quantity and from the calories entered in Add/Modify Inventory Items. If the calculation is not the one you want, you can type another value by hand.
Kitchen Order example. If you put all the doughs in layer 1, the sauces in layer 2 and the cheeses in layer 3, they come out together and in that order on the kitchen chit.

Prices can be set separately by order type: Dine-in Price and Delivery Price.
