The true cost of missing registrations
Every day, hundreds of Belgian companies risk fines simply because one worker wasn’t registered correctly in Check-in-at-Work (CIAW).
It’s not always intentional. Sometimes Wi-Fi fails, a badge is forgotten, or a site code is entered incorrectly.
But under NSSO law, even a small mistake counts as non-compliance, and fines can quickly add up.
Here’s what you need to know to avoid penalties and keep your operations audit-proof.
Understanding CIAW and your obligations
CIAW is Belgium’s official presence registration system for construction, cleaning, and industrial service sectors.
Every person working on a qualifying site must be registered in real time with the NSSO (National Social Security Office).
Since 2025, the system became even stricter with Check-in-and-Out-at-Work (CIAO) requiring both entry and exit times for every worker.
Failing to comply can result in:
- Administrative fines up to €6,000 per violation
- Inspection warnings and increased audit frequency
- Payment delays on public or subcontracted projects
The main reasons companies miss registrations
Even well-organised teams struggle to maintain perfect CIAW compliance when processes are manual.
Typical failure points include:
- Workers forgetting to badge in/out
- Lost connection or unstable Wi-Fi on site
- Wrong site ID or NSSO code entered manually
- Subcontractors not following your registration process
- Delayed file uploads to the NSSO portal
Each of these can trigger an incomplete or invalid registration putting your company at risk.
How to prevent CIAW fines: move from manual to automatic
The safest and most efficient way to avoid fines is to automate CIAW reporting.
Here’s how Suivo eliminates the risk:

With Suivo, compliance becomes part of your daily workflow. Not an extra task.
Preparing for CIAO 2025
Since January 2025, the CIAW system will expand into Check-in-and-Out-at-Work (CIAO).
That means:
- Both entry and exit times are mandatory
- Applies to more sectors, including cleaning and facility services
- Requires real-time reporting directly to NSSO web services
If you still rely on manual uploads, now is the time to switch.
Suivo’s Time Registration & Absence solution is already CIAO-ready, ensuring a smooth transition.
What compliance automation looks like
Once set up, Suivo manages everything automatically:
- Worker arrives on site → badges or uses the Time Logger App
- System logs presence → time, location, and NSSO site code
- Data syncs instantly → sent to NSSO, validated, and stored
- Dashboard view → HR and planners monitor live compliance
No more missing data. No more fines.
Real-world example, from risk to full compliance
A Belgian construction company with 100 mobile workers received three NSSO warnings in one year due to incomplete CIAW uploads.
After implementing Suivo:
✅ Automatic NSSO transmission for every site
✅ 0 missed registrations in 12 months
✅ Compliance reports ready in one click
✅ No further warnings or fines
“We haven’t missed a single registration since switching to Suivo.
It’s completely taken the stress out of CIAW.”
