Quotes, invoices, client tracking. All in a single standalone file that runs on your machine and stores your working data on your device. Not SaaS. No account in the file.
Designed for professionals who want to stay in control of their tools
Three things have been normalized that should not have been. Here they are.
Offline, nothing works
Without a connection or an active account, you can't work. If the service goes down, changes its terms or shuts down, your business stops with it. And every month the direct debit goes through.
Remote servers, off your machine
Addresses, amounts, invoices, files: all hosted elsewhere. You don't know exactly where, who has access, or what happens in case of a breach.
Half a day minimum
200 screens, 50 settings, 30 integrations that don't concern you. Half a day to understand, support to configure, and every update breaks a habit.
Your tool no longer lives with the publisher. It runs on your machine, with your data, like a notebook on your desk.
The studio runs in your browser, on your computer. It is not an online service: it does not need our servers to work day to day.
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.
It's a standalone file. Your data and your exports stay readable and exportable for years, without us.

Three long guides to fully understand before you buy.
Why move away from monthly subscription software. Anatomy of a Cahier Autonome, comparisons, use cases by profession.
Who is concerned and from when: the official schedule, approved platforms, the new mandatory mentions.
Planned contents: pricing over 1, 5 and 10 years, where your data lives, protection, the 2026 reform and migrating from these tools.
You receive your Cahier Autonome (1 standalone file) by email. You open it in Chrome, Safari, Firefox or Edge. It works immediately. 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. No user account in the file.
No. A Cahier Autonome runs locally in your browser, on your device: it is not an online service. Each studio is offered under an annual licence, renewed automatically, with no monthly fee: its price is stated on its page.
You request a new download link with the email address of your order. For your data, the file automatically exports to JSON, a text format you can store on Dropbox, Drive, or a hard drive. You choose where. Backup is under your control.
A studio is built for individual use, and your data is stored in the browser, not in the file: sharing the file does not share your data. Invoice Studio: one licence, one open session at a time; to change computer or browser, make a backup on the old one, activate the studio on the new one with your code, then import the backup there. Prélèvement Studio, sold in French for France, shares the centre's logbook, encrypted, across five devices in total, the manager's included: the manager invites each device.
Each studio runs in your browser, on your device, and stores your working data there. It connects to our server to check the licence. Depending on the studio, other features also go through a server: an encrypted shared logbook, forms sent to your clients, public data services. Each product page states what is sent, when and why.
Yes: new versions are available as long as the annual licence is active.
You export to JSON and PDF at any time. No lock-in: you leave with everything. For an annual licence, you cancel from the Stripe customer portal; access stays open until the end of the period already paid. Afterwards, Invoice Studio deletes nothing and switches to read-only: the backup, PDF and PNG files, printing, ZIP, CSV and accounting exports and the CII file stay available.
Those are online services (SaaS): the software and your data live on their servers, you work connected, with an account, and you depend on their availability. A Cahier Autonome runs on your machine: your working data is stored on your device and it works offline day to day. Invoice Studio is offered under an annual licence (7-day free trial, then EUR 99 per year, VAT not applicable, art. 293 B of the French General Tax Code), but it is not SaaS.
