Move your WhatsApp, Excel and receipt book into one system.
Built for Hong Kong tuition and hobby-class centres. Schedule classes, take attendance, bill monthly fees and session packages, send bilingual receipts and notify parents. Enter it once and everything else updates.
Pilot centres use it free for 3 months, then pay half price for 12 months.
No app for parents. They open a link to see the invoice and upload a payment screenshot.
What your centre does by hand today
None of it is hard. Together it fills the owner's evenings and the days of one or two staff.
Reschedules and make-ups over WhatsApp
A parent asks for leave or a tutor drops out, and you reply to each parent yourself. Miss one make-up and you get a clash or a double booking.
Fees tracked in Excel and a receipt book
Package balances and due dates are counted by hand. Overdue fees are chased one parent at a time, and the books get reconciled at night.
Attendance and billing kept apart
Attendance lives on paper or in a group chat, so deductions and invoices get typed in again. When a parent asks why a session was charged, someone has to dig.
One leave request, step by step
A parent asks for leave at 08:30. You approve it with one tap.
Leave, the make-up, the session count and the parent notice are linked. Staff confirm; nobody recalculates or retypes.
The parent taps Leave on their phone and can pick a make-up slot in the same course.
Staff approve it on the Leave page. The leave and the make-up go straight into attendance, and the student joins the make-up class roster.
The parent is notified straight away.
The tutor takes attendance on their phone. Only one of the two sessions is charged, so the package balance stays right.
Attendance → sessions → invoice
Tutors take attendance. Packages and fees follow.
Tutors mark present, late, absent, leave or make-up on their phone. Packages deduct by attendance, and per-session monthly fees count the sessions scheduled that month. Nothing is entered twice.
- One student can have a monthly class and a package class at once
- A class transfer counts as one continuous enrolment, so the package balance moves with it
- Tutor and room clashes are blocked the moment you schedule

Invoice → payment proof → receipt
One click at the start of the month bills every student.
Mid-month joiners are prorated by the sessions left, and early-bird and returning-student discounts apply on their own. Parents get an email with the PDF and a no-login link. After paying by FPS or PayMe they upload a screenshot, you approve it and the receipt goes out.
- Monthly fees, session packages, term fees and drop-ins
- Bilingual PDF invoices and receipts with your logo, signature and company chop
- Overdue fees and payment proofs waiting for review, on one billing page

Data security
Student and parent data stays with your centre.
Each centre's data is kept apart, everyone sees only what their role allows, and you can take all of it with you as an encrypted export at any time.
Each centre's data kept apart
Every record belongs to one centre and every read is limited to yours, so no other centre can see your students, parents or accounts.
Payment screenshots kept private
Transfer screenshots parents upload are never public; only signed-in staff can open them.
Export any time, encrypted
The owner can export all centre data to Excel, encrypted with AES-256 under a password you choose; the login password is asked again first.
Designed around how Hong Kong centres work
Parents message on WhatsApp, pay by FPS and PayMe, and expect receipts in Chinese and English. The system works the same way.
Parents upload a screenshot or deposit slip; staff check it and record the payment.
Every screen and every PDF in both languages. Each person picks their own.
The system writes the message; staff send it from the centre's own WhatsApp with one tap.
Owners, admins, staff, tutors and parents each see only what they need.
Now taking pilot centres
Academic tuition centres and hobby-class centres both welcome. We go through your current fee rules with you and set up your students and classes. Free for 3 months, then half price for 12 months.
