KP3 revealsDigital school logbook
Straight to parents’ Zalo. Teachers just tap once.
A logbook in your own brand, running on your school or center’s Zalo OA. Attendance, grades, comments, tuition reminders with a QR code. Parents don’t install an app, and you pay no SMS fees.

Dear friend,
If you’re looking at Digital school logbook to get more customers and more revenue without taking on more work yourself, this could be the most important page you read this week.
One-tap attendance (unexcused absences flagged automatically), comments and grades sent privately to each parent, monthly progress charts. Tuition reminders go out automatically with a QR code for the exact amount, and reconcile themselves when parents transfer the money.
Once the digital logbook is in: at six in the evening, the teacher finishes taking attendance. A few minutes later, parents get “your child is here” and the end-of-class comment on Zalo. When tuition is due, the reminder goes out by itself, with a QR code.
But before I tell you what KP3 does, let me ask you one question…

Paper, Excel and hand-typed messages
- Teachers take attendance on paper, the office types it into Excel, then messages each parent.
- Tuition reminders by hand, reconciled by hand. Miss a few students a month and millions of dong are gone without anyone noticing.
- Parents only hear from the center when something’s wrong.
If you nodded at even one line above, it’s not your fault. It’s a sign that the way you work now has run out of room to grow.
The good news: there’s a faster, surer way — and you don’t have to do it yourself.

Wait… this service isn’t for everyone
Because KP3 commits to KPIs, we only take on businesses we’re sure we can help:
- You already have a product or service that customers really buy — KP3 helps you sell more; it doesn’t find you a product.
- You’re ready to let KP3 lead on the expertise — you review and decide, but you don’t take the work back.
- No banned goods, no pyramid schemes, no scams, and nothing you wouldn’t dare tell your mother about.

Questions you might be asking yourself
Can parents who aren’t tech-savvy use it?
Yes. Messages land straight in Zalo, with SMS as a backup.
We use other software. Can it plug in?
Yes, through an API.
Are there monthly SMS fees?
No, because messages go through your own Zalo OA.
P.S. You could keep doing everything yourself, try a few more tools, hire a few more people — and hope next month turns out different.
Or you could spend 30 minutes talking with the KP3 team. We’ll show you exactly where you’re losing customers and how to fix it — free, no strings attached. Even if you don’t hire KP3, you leave with a growth map.
