A more thorough explanation:

Services

Services refer to work that is done in exchange for payment.

• A hairdresser cutting and styling a customer's hair for a fee.
• A plumber fixing a leaky faucet and charging for their time and materials.
• A lawyer providing legal advice and representation to a client for a fee.

These examples illustrate the definition of services because in each case, a person is performing a task or providing a skill in exchange for payment. The hairdresser, plumber, and lawyer are all providing a service to their customers, and they expect to be compensated for their time and expertise.
