Service fees are additional charges that businesses apply to cover the costs of providing a service. These fees can vary widely depending on the type of service and the company involved. For example, hotels may charge a service fee for housekeeping, while ticketing platforms might add a fee for processing online purchases. These fees are often disclosed during the transaction process, allowing customers to see the total cost before completing their purchase. Understanding service fees is important for consumers, as they can significantly impact the final price of services like travel bookings or event tickets.
