There's two types of booking notes affiliated with reservations.
To allow your customers the ability to add online notes to their reservations, you can enable this setting by navigating to Settings > Online Booking > Toggling on Online Notes.
This gives them permission to add notes specific to their reservation, prior to them arriving for their tee time! To view these notes, you can hover over note icon on your tee sheet.
Note: The online notes appear in blue on your tee sheet!
2. Internal Notes
Your staff can add internal notes to reservations, as a way to communicate with each other. To add these notes, you can click into a specific reservation, add it in the yellow section below the reservation.
Note: These notes are not visible to members who have access to the tee sheet.
