For accountants and bookkeepers
Your clients with a one-person company in France keep asking the same questions between visits. Here is what we have built for those questions — free to use, free to put on your own site, and nothing to sign.
Put any calculator on your own site
One line of HTML. It answers a single question on the same engine as everything else here, updates itself when a rule changes, sets no cookies and asks your visitors for nothing. The only thing we ask is the link back the widget already carries.
Paste it anywhere in your page. Nothing to maintain, and no script to add.
See the full page for this oneWhat a client can hand you
A subscriber gets a report they can give to you rather than asking you to reconstruct it. Every figure in it names its source.
- A PDF of the ranked report, with the action for each lever
- A read-only link to the same report, no account needed at your end
- A source and a tax year printed next to every figure
- The rule changes since it was computed, dated
A deadline calendar to share
The filing and payment dates for this market, as a calendar your clients can subscribe to. It reminds them a week ahead so you do not have to.
Open the calendarWhat changed, and when
A dated log of the rule changes that actually move a freelancer’s numbers, with the source that established each one. Useful for your own client mailings.
Read the change logWhere the numbers come from
Rules live as dated data, not as code: the 2026 set was last checked against primary sources on 2026-07-20, and every figure carries the source it came from. You can check any of it without paying us anything.
If you find a figure wrong, tell us. We correct it, record it in the change log, and refund the client who paid for it.

We do not have a partner programme, a revenue share or a white-label product — if that is what you are after, we would rather say so than waste your time. What we do want is to hear from practices using this with clients, and what is missing.
