For Tutors: Many Small Sessions, Many Parents, One Calendar

A tutor’s billing maths is unusual: small amounts, many clients, and a third party — the parent — paying for the second party — the student. Twenty-five euros a session, four sessions a week, fifteen students. That’s sixty invoices’ worth of activity a month at amounts too small for any of it to justify thirty minutes of spreadsheet work.

The friction adds up. So does the parent’s impression every time an invoice arrives.

Meet Vaida

Vaida tutors English in Klaipėda — preparing 14- to 18-year-olds for the school-leaving exam, plus a few adults rebuilding their English for work. A normal week: 20 sessions across 15 students, mostly online via Google Meet, some in person at the public library or the student’s home. Sessions are €25 each.

Most students rebook in monthly cycles — a parent buys a pack of eight sessions and they’re consumed twice a week. A few pay session by session. One adult is on a corporate budget and wants a proper invoice with a company VAT number every two weeks.

The same shape applies to music teachers running piano or guitar lessons, and to academic tutors for math, physics, or chemistry. The cadence is identical: lots of small transactions, parents paying, scheduling shifts week to week.

The Real Billing Reality

Two pain points dominate:

• The amounts are small but the count is high. Forty invoices a month at €25 each is the same paperwork as four invoices at €250 — except the four would be quietly tolerated and the forty become a Sunday-evening Excel session. Each invoice needs the student’s name on the line, the dates of the lessons, sometimes a note about cancellations.
• The parent reads the invoice. The student attends the lesson, but the parent receives the PDF, reviews it, and forms an impression of how organised the tutor is. A clean, on-brand invoice in their inbox at month-start is a quiet form of marketing — and a sloppy one, the same. Many parents also forward the invoice for tax-deduction purposes (children’s education expenses qualify in several jurisdictions), which means it has to look like a real document.

The cadence has another quirk: rescheduled sessions land in the next month’s invoice rather than the original one — so the bill has to reflect when the lesson actually happened, not when it was booked.

How Haiku Fits a Tutor’s Practice

Three pieces of Haiku do the work:

• Bulk-create monthly invoices from your calendar — every session on Google Calendar; at month-end, point Haiku at the previous month, group by student name (or parent’s company for corporate clients), and one invoice per family falls out with every session dated and listed. The rescheduled lesson lands in the right month automatically. Bulk-create invoices from Google Calendar.
• One-off invoice in under a minute for a session pack paid up front, a new student starting mid-month, or the adult’s corporate two-week cycle. How to create an invoice.
• Send from your own email via SMTP if you use Outlook, iCloud, a school-issued address, or any provider that isn’t Gmail. Same effect: the parent’s inbox sees “Vaida Tutoring” not no-reply, and the sent folder is the proof when somebody asks for “last March’s invoice” in May. Set up email sending via SMTP.

Whether you teach languages, music, or academic subjects — the workflow is the same: every session on the calendar, one invoice per family at month-end, branded so the parent’s inbox treats it like a real bill.

When It’s Not the Right Fit

If you teach through a school or platform that handles invoicing for you, you don’t need this — but most tutors with even a handful of private students do the billing themselves. If your sessions live somewhere other than Google Calendar, the bulk flow won’t connect; the one-off invoice still works.

Getting Started in 3 Steps

1. Sign up free at haiku.lt and connect Google — 500 invoices in the free plan covers a year of mid-volume tutoring.
2. Issue one invoice manually for each billing pattern — a per-pack family, a monthly family, the corporate adult. Three templates Haiku reuses.
3. At month-end, run the Calendar wizard, grouping by student or family name. First month is fifteen minutes (clean up the calendar naming); from the second, five.
