Each student has a fixed monthly tuition amount and due date. The system sends automatic WhatsApp reminders to parents 3 days before the due date. Mark payments as 'paid' with one tap. End-of-month dashboards show who paid and who's overdue. 95% faster than manual spreadsheet tracking.

Yes. Tag the instrument per student. The same system can hold 5 piano students, 3 violin students, and 2 guitar students. Monthly reports show revenue breakdown by instrument.

Messages go out 3 days before due date, on the due date, and 1 day after. Tone is professional and polite — you don't personally 'chase' anyone. Delays beyond 3 days move into a manual call list.

Add extra lessons as separate payment line items beyond the monthly tuition. The end-of-month report shows 'standard tuition + extra lessons' separately. Parents receive a detailed breakdown.

Each student is configured as 'fixed monthly fee' or 'per-lesson billing'. Fixed monthly includes vacations (per the contract). Per-lesson bills only for lessons taught. Most music schools prefer fixed monthly for predictable revenue.

From the financial reports section, export the annual income breakdown as PDF or CSV with one tap. Monthly distribution, per-student revenue, and payment-method breakdown (cash/transfer) are all auto-calculated. Format your accountant can use directly.
