Who publishes Idonis
Idonis is published by Vanbe SRL, a company under Belgian law registered with the Crossroads Bank for Enterprises under number 0561.776.191 and based in Montigny-le-Tilleul. The responsible publisher is Charles Vanbeneden, managing director of Vanbe SRL. Vanbe SRL's accounts are public, like those of any company: its company page.
Idonis is an information and analysis tool. It is not affiliated with the Crossroads Bank for Enterprises, the National Bank of Belgium or the Belgian Gazette: it reuses their publications and cites them.
Where the data comes from
- The company register (CBE): the open data of the Crossroads Bank for Enterprises (FPS Economy) — name, legal form, date of incorporation, status, registered office, activities. Synchronised every day.
- The annual accounts filed with the Central Balance Sheet Office of the National Bank of Belgium, taken in as they become available, with their filing date.
- The Belgian Gazette: the annexes on legal entities — incorporations, amendments to the articles, appointments, proceedings. The public company page shows their date and type of deed.
- The Peppol network (OpenPeppol): a company's registration for e-invoicing, checked once a day in the network's public directory.
How it is processed
Filed accounts are read item by item, using the codes of the National Bank's schema. When a filing only exists as a scanned PDF, its figures are extracted automatically; these figures, like an extracted balance sheet that does not balance, are flagged on the company page with limited confidence.
Idonis distinguishes three kinds of figures: a published amount is as it appears in the filed accounts; a calculated ratio is derived from them by a fixed formula, shown on the company page; an estimated figure comes from a model and carries a range and its label.
The Idonis soundness score applies the same rules to every company; its method is published in full. For directors, Idonis shows the mandates as they are published: no person is scored or assessed.
How it is checked
Every figure points to its source: the filing and its financial year, the deed and its publication date. The company page links to the original publications, so that you can redo the reading yourself. Its "Updated on" date is that of the most recent fact it shows: latest filing, latest publication in the Gazette or latest check.
The score itself is also checked in hindsight. Back-test on 1,072,223 filed accounts for the financial years 2022 and 2023: within the following 18 months, about 1 in 780 companies graded A was declared bankrupt in the Belgian Gazette, against about 1 in 53 for grade E (measured on October 27, 2026) — group rates, not a forecast.

Reporting an error
Does a figure, a publication or a mandate look wrong to you? The "Dispute the score or report an error" link on each company page, or this form, sends it to us; you can also write to contact@idonis.ai. We check it at the source and reply in writing. An error on our side is corrected at the source, and the score is recalculated; we never change a score by hand. If the filed accounts themselves are wrong, only a corrected filing with the National Bank can fix them.
A person named in a published mandate can exercise their rights over their data: the procedure is described in the privacy policy (in French).
