There is an option in BookingsPlus to create a Non-Billable client.
Any bookings which do not need to be charged for during opening hours need to be added to BookingsPlus to limit disruption and to ensure Administrators and Site Staff are fully aware of what is happening in the venue.
If required, there can be a number of Non-Billable Clients e.g. Maintenance, Parents Evenings, Performances etc. Just think about the analysis which will be required from the system.
When a client is set up or edited, you'll notice there's a box at the bottom of the page to select if you are creating a Non-Billable client. This will mean that the booking is non-chargeable & will show up in Grey on the calendar.
