What is used to track the source of revenue and offer discounts in a system?

Promotions are designed to be comprehensive marketing strategies that not only track the source of revenue but also provide mechanisms for offering discounts to customers. In NetSuite, promotions can be tailored to target specific customer segments or incentivize particular purchasing behaviors. This enables businesses to assess the performance of their promotional campaigns effectively and understand how these promotions influence sales and customer engagement.

While discount codes are specifically created to provide discounts at the checkout, they do not necessarily track revenue sources. Static groups refer to fixed customer groupings that do not change based on criteria, thereby lacking the dynamic capabilities necessary for tracking revenue sources. Dynamic groups, although more flexible, generally serve to categorize customers based on specific criteria rather than focusing on revenue tracking and discount application.

Promotions integrate both the tracking of revenue sources and the offering of discounts, making them the most suitable choice for achieving the stated objective in the question.
