Tutors bill one person for another person's lessons: the parent pays, the student attends. The invoice that works names both, lists every session, and makes paying take less time than scheduling.
The parent or whoever pays — they're the billed party. Put the student's name in the line items, like this template's example, so report-card season and your books tell the same story.
Set the policy in your terms — "24-hour notice to reschedule; late cancels billed at half rate" — and bill late cancels as their own line. A policy that lives on every invoice never feels personal.
One line — "Package — 10 sessions, prepaid" — invoiced before sessions begin, then track the dates in the notes of a monthly zero-balance summary, or keep your own log. Prepaid means never chasing session twelve.
Turn on "Get paid online" and the invoice includes a pay page that takes cards and bank transfer. Parents juggling three schedules pay the invoice they can settle from a phone.
