Abstract: In methods and systems for allowing a user to book an appointment with a service provider, and for charging the service provider a fee for a successfully booked appointment, a user provides a search request via a client computer. In response, a calendar system provides search results including a link corresponding to a service provider. Upon user selection of the link corresponding to the service provider, the calendar system provides a calendar view showing available time slots of the service provider. The user selects an appointment time and available service, which initiates an appointment request to schedule an appointment with the service provider. Upon determining that the appointment request can be accepted, the calendar system books the appointment. Then the calendar system charges the service provider a pre-arranged fee for the booked appointment. In some embodiments the calendar system also collects payments from the user for the services provided.
