Trusted by tutoring businesses
In France, at-home private tutoring entitles your students to a 50% income-tax credit, as long as you give them an annual tax certificate (attestation fiscale). Filling one in by hand, student by student, costs hours every January. Kadrella builds it from the payments already recorded: one document per student, with the yearly total, ready to send.

The founder's story
Built by a teacher, for his own tutoring business.
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.

Frequently asked questions
What is an attestation fiscale?+
It is the annual document you give each student or parent so they can declare what they paid and claim the French tax credit for personal services.
Is the tax credit really 50%?+
Yes. At-home tutoring qualifies for an income-tax credit equal to 50% of the sums paid, within the annual ceilings set by French law.
Do I have to type in the amounts?+
No. Kadrella uses the payments already recorded for each student and totals the year automatically.
