If there are services that you offer that do not have a set price you can add a setting to your service so that the customer will not see a set price on the online customer booking portal.
When adding or editing an Additional Service simply click on the highlighted toggle, to enable this feature. As the price of the service will not be shown to the customer on the online booking system, it is helpful to give the customer indicative pricing by adding note in the Description field, eg; Prices range from $60 to $100 depending on breed/pet size.
Once a service has been added to a booking you can edit the price of the service by clicking on the 'Services' page on the booking menu on the left hand side of the page.
Once you set the price, just click on the green 'Update Additional Services' button to save the changes.
