Chiron guide · Flanders · IBP
How does Chiron work?
Since the reform of individually remunerated passenger transport (IBP) in Flanders, operators and drivers must meet new administrative obligations. Chiron is central to that system.
But concretely: what is Chiron and how does it work day to day?
In short
Chiron is not an app the driver opens on every trip. It is an official register fed by the operator’s management or dispatch software — at each key step: booking, departure and arrival.
What is Chiron?
Chiron is the digital platform set up by the Flemish authorities to register certain information relating to trips carried out under IBP.
The goal is simple:
- improve transparency in the sector;
- facilitate controls on the road and administratively;
- ensure compliance with Flemish regulations;
- replace certain manual administrative procedures with reliable digital transmissions.
Today, dispatch and taxi management software can automatically transmit the required information to Chiron — without the operator having to re-enter every trip by hand.
Chiron does not replace your business software. It connects to it: your management tool remains the centre of your activity; Chiron is the regulatory register.
Who must use Chiron?
Chiron mainly concerns actors of individually remunerated passenger transport in Flanders, under the IBP reform.
| Profile | Role regarding Chiron |
|---|---|
| IBP operator | Legally responsible — must ensure trips are correctly declared |
| Transport company in Flanders | Must connect its software to Chiron |
| Driver under IBP licence | Generally does not interact directly with Chiron |
| Taxi software vendor | Transmits data on behalf of the operator |
Even if the driver never opens Chiron, their trip data can (and often must) be transmitted via the software used by their operator.

How is a trip registered?
The system works on three key moments in the trip lifecycle. At each transition, connected software sends a message describing the current status of the trip.
1. Booking (reservatie)
When a customer books a trip — by phone, app or platform — certain information is recorded and transmitted:
- date and time of the booking;
- planned pickup location;
- administrative information required by regulations.
This step confirms that a job has actually been planned.
2. Departure (vertrek)
When the job actually starts, a departure event is generated. This tells the authorities that the trip has actually started, and not just been booked.
3. Arrival (aankomst)
When the job is complete, an arrival event is recorded. The trip is then considered closed in Chiron.

Important: these are not three separate systems. It is a single flow — software sends the full trip status at every status change.
Does Chiron record payments?
No.
Chiron is not an invoicing or accounting system. Customer payments, platform commissions (Uber, Bolt, etc.), driver income and accounting data remain managed by your business software or platform.
Chiron and invoicing serve different purposes: one tracks trips for regulatory compliance, the other manages your business activity.
Is Chiron mandatory?
Exact obligations depend on your activity, licence type and the regulatory framework applicable in Flanders.
In practice, IBP operators must ensure that:
- their internal processes meet Flemish authority requirements;
- their tools (dispatch software, fleet management) are capable of transmitting the required data;
- transmissions are complete and reliable over time.

What happens if something goes wrong?
The most common mistakes are not bad faith, but a gap between reality on the ground and what Chiron receives.
| Error | Possible consequence |
|---|---|
| Missing booking | Trip not traceable from the start |
| Departure not recorded | Inconsistency during a control |
| Arrival missing | Trip considered unfinished |
| Incomplete information | Transmission rejected |
| Software ↔ Chiron connection issue | Data loss on one or more trips |
These situations can cause problems during a roadside control or an administrative audit.
Sandbox vs production: two environments
Before transmitting real data, operators and software vendors usually test their integration in a sandbox environment (test), separate from production (real data).
| Environment | Use |
|---|---|
| Sandbox | Tests, certification, technical validation |
| Production | Official transmissions of real trips |
The sandbox → production transition is part of the compliance process. See: How to pass Chiron certification.
Why use software connected to Chiron?
Managing these declarations manually quickly becomes unmanageable as trip volume grows — especially for fleets with multiple drivers or operators active on several platforms.
Software connected to Chiron enables you to:
- automate transmissions at every status change;
- reduce the risk of human error;
- keep a history of sent events;
- facilitate administrative controls;
- save time daily for the operator and drivers.
The driver keeps doing their job. Software handles compliance in the background.
Conclusion
Chiron has become a central part of individually remunerated passenger transport in Flanders.
Although the system remains largely invisible to drivers day to day, it plays a decisive role in regulatory compliance for IBP operators.
Understanding how it works — booking, departure, arrival — helps you better anticipate your administrative obligations and avoid mistakes that could cause problems during a control.
