How the service works
Three offers, one journey: you connect your Odoo, we read your books from outside, and you get the file or the database.
Belgian accounting, Odoo 19.
From the first screen to the file
Connection — give us the address of your Odoo and an API key you create yourself (keep it, you will need it again).
Diagnosis — we check that your database is compatible and work out the price. To do so, we read a few totals, an investment table and the size of your attached documents: aggregates only, never an individual amount, never a label.
Payment — you choose your options (for example: take over the PDFs of your invoices too?) and you see the total price (the full grid is here). One order per company and per financial year. Accounting firms and fiduciaries pay by pack of files, from 25 € per file, and activate each client file with their pack code: see the packs.
After payment, we ask for your API key again — we did not keep it — to read your database. Your data is kept only while your delivery is being prepared, then deleted.
Delivery — depending on the offer, you download files (your annual accounts for the National Bank, your Biztax dossier) or an Odoo 19 database fed with your accounting. What each one contains is on its own page: Biztax, BNB, accounting migration.
The diagnosis is free, reads totals only and commits you to nothing: you decide afterwards whether to go on.
What each offer produces
For your annual accounts, we produce an .xbrl file, an xlsx file and a pdf that let you check carefully what you are about to send. And we replay the Central Balance Sheet Office's official checks on the .xbrl: you get their verdict as it is.
For the corporate income tax return, our tool prepares the .biztax file for assessment year 2026 and gathers the PDF annexes in one place.
In the Biztax module, a checklist shows what is still missing from your file, and you upload the PDFs the administration asks for in the same place.
The module replays the FPS Finance's official checks on your file and hands you their verdict as it is: if a box is a problem, you are told at once by a clear error message.
For the corporate income tax service, we copy your accounting — chart of accounts, balances, investment lines, and down to the entries, invoices and attachments depending on the takeover you choose — into a recent version of Odoo carrying the module that will build your .biztax file. The rest does not follow: not your custom modules, not user accounts and rights, not payroll, stock, messages or reports. The list is closed: it is article 4.5 of the terms of service.
We host that database. It is downloadable at any time, and it is erased after 14 days; you can buy more time, 7 days at a time, when you order. Would you rather nothing left your own machines? Then install the Anthracite Biztax module in your own Odoo — an Odoo you host, or odoo.sh (a paid module cannot be installed on Odoo Online).
Our tool lets you migrate your accounting from Odoo 17, 18 or 19 to version 19: into a database we host, onto your own server, or onto your standard Odoo Online (a database whose licence you pay for at Odoo's rate). An older version? Write to us.
The takeover of your entries, the whole history, is free, whatever the size of your database. The full takeover (invoices, contacts, attachments) has a price, and it is published: the grid is on the pricing page, there is no quote to wait for.
How we guarantee the security of your data
1 - If you can, give us a key that cannot write
In Odoo, an API key belongs to a user. Every door the user can open, the API key can open! We recommend creating a "technical" user who has only the right to read the accounting (all of the accounting, but read-only), and creating the key in that user's preferences > Security tab.
Careful: on Odoo Enterprise, one more user costs a licence. We do not require it — we are not going to make you pay for a seat in order to buy from us. If that worries you, create the key on an existing user instead.
2 - On our side, we have restricted what our program may do
Whether the key can open every door or not, we, on our side, have given our application very narrow rights. It can only READ your data. Concretely, here are the commands our application is able to run:
fields_get · search · search_read · search_count · read · formatted_read_group · has_access · has_group
3 - And we never keep your key
Not in a database, not in a file, not in a session, not in a log line, not in a redirect URL. It lives in memory for the length of one reading. You can even revoke it as soon as your delivery is in your hands.
The list of what our program may read is public, at service.anthracite.brussels/sante, and the program checks at every start that it applies exactly that list — otherwise it refuses to start. The modules we sell follow the same list.
What this service does not do
- We do not file anything for you. Not with the National Bank, not on Biztax. The file is yours; you file it.
- We do not draw up your annual accounts. Drawing them up is reserved to ITAA professionals; we put figures that already exist into the form the recipient expects.
- We never write into your source accounting. We only read it; your legal books stay where they are, retention obligations included.
- We do not audit your accounting. If a figure is wrong in your books, it is wrong in the file. The takeover is checked to the cent against the source: the copy is faithful, which does not make the accounting right.
