Studio Billing and Make-up Lesson Agent

Running a music studio means monthly invoices, cancellations, make-up lessons and the occasional dispute about what was agreed. At month end this agent reads the lesson calendar, counts lessons per student, and applies the studio's written policy on notice periods, credits and make-ups. A student who cancels with at least 24 hours notice earns a make-up; later cancellations are charged. It drafts invoices that show the calculation line by line, and the teacher approves every invoice and any exception. It offers open make-up slots for eligible missed lessons and tracks whether they are used before they expire. After sending, it checks payments; if an invoice is unpaid after 14 days, it drafts a polite reminder for the teacher and checks again a week later. Edge case: lessons the teacher cancelled are always credited or rescheduled, whatever the notice rule says.
