In a service buy, how is the quantity usually represented?

In a service buy, the quantity is typically represented as a fixed unit, often directly corresponding to a single instance of the service provided. This is why it is commonly indicated as "1" in many systems. Services are usually sold as discrete events or contracts rather than in varying quantities like physical goods.

For example, if you were hiring a consultant for a project, you would generally consider the service as one complete engagement rather than trying to quantify it in percentage terms, dollar amounts, or other units of measure. This makes the representation of quantity in service buys straightforward, reflecting the singular nature of the service agreement.
