Invoicing
Generate invoices from the lessons given, always know who's paid, and chase late payers without thinking about it.


Trusted by tutoring businesses
Invoicing private lessons is three repetitive tasks: counting lessons, producing one invoice per student, tracking payments. Kadrella starts from the schedule you already keep to generate PDF invoices compliant with French rules, with sequential numbering and lesson detail. The bank connection reconciles transfers automatically.

The founder's story
I've taught maths and computer science since 2020, and I run my own private-tutoring business, Head of Science: 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.
