For music school owners
You started with music. Not with admin.
Timetable, contracts, payments and the rules on false self-employment. One system handles it, you only steer. So you own your school again, and your time.
- Your admin runs automatically, you stay in control.
- Teacher contracts based on franchise law, designed to prevent false self-employment.
- You no longer carry the school alone. Your teachers carry it with you.
A first version has been running since 2019 at Novae Popschool, the school of founder Collin Leijenaar.

Recognise your week?
You wanted to pass on music. Now you're mostly a bookkeeper.
You picked up an instrument because it moved you. You started a school to pass that on. And now you hardly touch that instrument, because the school takes all your time.
- It's half past ten, the kids are in bed, and you're still working out who paid this month.
- A parent emails asking why a lesson was charged during the holidays. You can't quickly check whether she's right.
- Your piano teacher asks for an extra day. You have to look in three places before you can answer.
- You lie awake wondering whether a teacher contract would pass a tax audit.
- You call that one parent who hasn't paid, have that awful conversation again, and it stays with you all evening.
- You carry the school alone. Your teachers teach their lessons and leave.
The shift
From being run by your school to making music again
Same school, same passion. A different way of working.
Without Klario
- You work for your school. Employee, not owner.
- You started as a musician and hardly play anymore.
- Sixty to eighty hours a week. And the question: is this it?
- You chase payments, with all the friction that comes with it.
- You carry the school on your own.
With Klario
- You're the owner. You steer, the system does the work.
- You have time again for your instrument, your lessons and your students.
- From 60-80 hours a week to half a day.
- Invoices and reminders run automatically. The emotion is gone.
- Your team takes ownership, and stays independent.
"I could tour with my band again while the school kept running and growing."
False self-employment
You work with freelance teachers. The tax authority is watching.
Almost every Dutch music school works with independent teachers. Since 1 January 2025 the Dutch tax authority is enforcing the rules on false self-employment again. For a music school this is not a detail. It affects your whole teaching staff.
Often there seems to be only one choice: carry the school alone, or involve your teachers so deeply that it starts to look like employment. Klario solves this with a franchise structure as the foundation and one shared system as the engine. Your teachers take ownership, and stay independent business owners.
Klario is designed to prevent false self-employment. The working relationship follows the Dutch franchise law, and you can show that when the tax authority looks.

You make music again
Everything in one place. You steer, Klario does the work. And you get back to why you started.
Why Klario gets this
Built by a music school owner who went through it
Klario wasn't dreamed up by a software company. It was built by a musician and school owner who got stuck and found a way out. He went from sixty to eighty hours a week to half a day.
That school is Novae Popschool: over 28 years of practice and 300+ students a year. A first version of Klario has been running there since 2019. Klario 3.0 is being built right now.
