Sessions are pulled live from your tutoring Google Calendar. Each event = one billable session.
Amount = (event duration ÷ 60) × the student's rate. Track unbilled → invoiced → paid.
One-time setup: link your tutoring calendar
Open Google Calendar → settings of the calendar you log tutoring sessions in → scroll to "Integrate calendar" →
copy the Calendar ID (looks like abc123@group.calendar.google.com) and paste it below.
