As you might already know, you can group together services and/or products into pre-paid packages for your clients to purchase. They can redeem their pre-paid package items as they go. If you haven't yet set these up, click here to learn how.
When you book in a clients pre-paid service into the Appointment book, it will display as the colour grey. By default the colour doesn't change if you flag the appointment as Arrived. However if you would like the grey pre-paid service, which is a part of a package, to turn green when flagged as Arrived, you can enable a setting.
Go to Settings, then into Appointment Settings, then tick Enable Arrived flag colour for Paid Appointments, click Save.
Now on the Appointments page, go to the clients appointment, click the clients name on it and choose Flag As... then tick Arrived.
The clients pre-paid appointment will turn green on the Appointments page.
