When you’re setting up your providers there’s a section that’s called "Services Provided". All you have to do is check or uncheck which Service they do or do not provide. If you would like edit their services at a later date, please do the following:
Select "Manage" at the top of the screen. Select "Providers". Click the blue "Edit button" beside the provider you'd like to edit. Select "Services Provided". Then check or uncheck the services.
