Which term refers to a help desk that helps generate revenue through service charges?

The term that refers to a help desk that helps generate revenue through service charges is "profit center." A profit center is an organizational component or business unit that is responsible for generating revenue and is evaluated based on its profitability. This means that the help desk not only provides support services but also charges for those services, thus contributing to the overall profit of the organization.

In contrast, a service center typically focuses on providing support and may not be directly responsible for generating profit. A cost center, on the other hand, is a department that incurs costs but does not generate revenue, making it less relevant in this context. A billing center primarily focuses on invoicing and payment collection tasks but is not defined by the capacity to generate revenue from service charges in the way a profit center is. Therefore, the designation of profit center accurately reflects the dual role of a help desk that both assists users and generates income through fees for those services.
