The first step in using portions is to create the portions themselves, for example, 1st Half and 2nd Half. You can use a portion's Price Multiplier setting to alter the price of a modifier when it is applied to that portion. For example, consider a pepperoni modifier that normally costs $6 when applied to a whole pizza. If the pepperoni modifier is applied to the 1st Half portion of a pizza, and the Price Multiplier setting for the 1st Half portion is set to 0.5, then the cost of the pepperoni modifier when applied to the 1st Half portion is $3.

For advanced pricing strategies, the Toast platform calculates the final price of a modifier in two steps. First, it determines the price of the modifier, independent of any portions, and then it applies the Price Multiplier to that price. For example, consider a pizza toppings modifier group that uses the following sequence pricing:

Initially, the Toast platform uses the sequence in which the toppings are added to the order, not whether the toppings are applied to the entire pizza or a portion of the pizza, to determine the prices. Here is how the Toast platform determines the initial price for each topping:

Next, the Toast platform multiplies the cost of each modifier by the Price Multiplier configured for each portion. If both the 1st Half and the 2nd Half portions have a Price Multiplier of 0.5, then the final modifier prices are:
