Emphasis on the quantitative aspects of products sold (ie: portion size, price) and services offered (the time it takes to get the product) is called

Calculability

Explanation:

A transaction can be defined as a business process which typically involves the interchange of goods (products), financial assets, services and money between a seller and a buyer.

A product can be defined as any physical object or material that typically satisfy and meets the demands, needs or wants of customers. Some examples of a product are mobile phones, television, microphone, microwave oven, bread, pencil, freezer, beverages, soft drinks etc.

A service can be defined as an intangible (immaterial), non-physical activities, satisfactions or benefits that are offered for sale by a business service or provided to accompany the sales of a product. Thus, it's an action that involves offering something to a service taker or customer in return for an amount of money as payment.

In Business management, calculability is the emphasis of a business firm on the quantitative aspects (portions, price, size) of products sold and services offered (the time it takes the consumer to get the product). Thus, calculability avails a business firm the opportunity to emphasize on the quantity of product sold rather than a qualitative factor.
