How it works
Your tools, already connected.
Kadrella fits the tools you and your students already use, so nothing has to be typed twice.
From the first message to payment.
A student writes on WhatsApp. Kadrella suggests a slot, schedules, sends the reminder, issues the invoice and reconciles the payment. You confirm with a word.
- ✓ Slot proposed & confirmed
- ✓ Reminder sent automatically
- ✓ Invoice issued & payment reconciled
The founder's story
Built by a teacher, for his own tutoring business.
I teach maths and computer science, and I run my own private-tutoring business: several teachers, around a hundred students. I'm also a software engineer. In 2024, I started building this tool for myself, because tracking payments and chasing late ones took every Sunday. I've used it every day since. Kadrella is that same tool, opened up to other teachers.

Comparison
Built for private tutors, not schools.
Most tools target centres and agencies (portals, multi-branch, LMS). Kadrella focuses on what you need, and does what the others don't.
