We reverse the contract.
Your software and your data should not have to live at the publisher's, 2,000 kilometers away. Here is what we stand against, and what we defend.
What we have normalized
Three things that should not be normal.
Pay more, every year
A SaaS invoicing tool is billed every month for access to a hosted service, and its price keeps rising year after year.
Wait for updates
You discover new features when the editor ships them. You have no say.
Stack up accounts
1 account per tool, 1 password, 1 2FA, 1 online access. For 1 person.
“A Cahier Autonome is not an access to our server. It is a file that works on your machine.”
What we defend
Three principles, non-negotiable.
Real control
The studio runs on your machine, in your browser. It does not need our servers to work day to day, and your exports stay readable and usable without us.
Data privacy
Each studio stores your working data on your device. It connects to our server for the licence and, depending on the studio, for specific features described on its product page.
Radical simplicity
If you can open a PDF, you can use a Cahier Autonome. No 200 screens, no 50 hidden settings.
How it is built
A deliberately minimal stack.
01
A standalone file
Everything is embedded: UI, business logic, styles, fonts. The same format as the web pages you read every day.
02
Local browser storage
Your entries live in your browser's local storage, on your device.
03
JSON and PDF export
At any time, you export your data in readable, transferable, archivable formats.
04
20-year compatible
This format is the most backwards-compatible on the web. Your files and exports will stay readable in 5, 10, 20 years.
For whom
Built for those who want to stay in control.
Freelancers, small businesses, regulated professions. Anyone running their activity with a few precise tools who no longer wants their tools and data to live at a publisher's.
Our commitment
We commit to not owning you.
Coherent with what we just read?
Invoice Studio applies the manifesto to invoicing: a standalone file that runs on your machine, your data on your computer. 7-day free trial, then EUR 99 per year (VAT not applicable, art. 293 B of the French General Tax Code).
