• On the "Modifiers" tab, in the "rule type" property, the rules for calculating modifier prices are defined (manual editing, constant, formula). For more details, see the "Price Types" section.

• At the cash register, the price of the modifier will increase the price of the dish (250 rubles), it will be calculated as 30% (250 * 0.3 = 75 rubles).

Determining prices for a group of modifiers

In the "Price Types" directory, it is possible to set calculation rules not only for all modifiers, but also for individual modifiers and groups of modifiers.
To do this:

• On the "Modifiers" tab, create a new calculation rule. In the window that appears, select the scope of the formula "Modifier Group" (by default, the rule type "formula" is created).
  
  
• Select the modifier group for which you want to set the price calculation rule.
  
  
• The rule type for a new calculation rule can be changed manually (for example, to manual editing).
  Note the "Constraint" and "Scope" properties in the "Main" property group. They determine what the specified price calculation rule applies to.
  In the example below, this is the "Sauces" modifier group. For example, the prices of all modifiers are calculated using a constant, but for the "Sauces" modifier group, the price is set manually.
• Calculation rules can also be defined separately for each modifier.
  On the "Modifiers" tab, create a new calculation rule. In the window that appears, select the scope of the "Modifier" formula (by default, the "formula" rule type is created)
  
  
• Select the modifier for which you want to set the price calculation rule.
