well you see, first we must differentiate between use-value and exchange-value.
We find that exchange-value is an expressesion of value, which is socially-necessary labour-time.
Just as every commodity must be a use-value in order to have exchange-value, so too must a service have a use-value in order to be commodified and sold.
In this case the service worker produces value in their socially-necessary work which produces a use-value for the buyer.
The buyer, in consuming the use-value of this service, pays the price, which is an expression of the exchange-value of the service.
Our capitalist has paid the worker the value of their labour-time for the day, and the worker has provided services of a certain value which is higher than the value of their own labour time. The capitalist keeps the additional money paid, thus realising the surplus value in the service production.
