Dozens of locations, shifting crews
Paper lists and stand-alone time clocks cannot keep up with a real-time registration obligation.
Presence registration
Check in with one tap. NSSO declaration, automatic and on time.
CIAO Clean, our registration solution for the cleaning sector: your workers check in and out in an app that speaks 11 languages, and every movement reaches the NSSO automatically and within the legal deadline — followed through to the final response.
- Automatic NSSO declaration within the legal deadline
- App in 11 languages
- EU-hosted, GDPR-compliant
01 The problem
Sound familiar?
The legal deadline is not a job for people
Every check-in has to reach the NSSO almost immediately — passing it on by hand does not scale, and forgetting it becomes a finding at inspection.
Multilingual crews, monolingual instructions
Registered wrongly or not at all, because the app or the explanation does not speak the language of the shop floor.
You only see registration errors when the inspection does — unless your system follows them up itself.
02 How it works
From one tap to an accepted declaration
-
The worker checks in
One tap in the CIAO Mobile app, in their own language; the geofence confirms presence at the right work location.
-
CIAO Clean files the registration with the NSSO
Automatically, within the legal deadline, signed with your own NSSO certificate — and guaranteed never twice.
-
You see the result
Every declaration is followed through to the final government response, in plain language in your dashboard and reports.
Behind the scenes: every movement is signed with your own NSSO certificate, sent within the legal deadline, and followed through to the final government response.
03 What CIAO Clean does
Register. File. Follow up. Prove.
One tap, in their own language
The CIAO Mobile app runs in 11 languages, with PIN-first sign-in, a dark theme for outdoor work, and buttons that work with work gloves on.
Filed automatically, never twice
Every qualifying movement reaches the NSSO within the legal deadline. Three independent safeguards rule out duplicate declarations; failed submissions are retried automatically and reported rather than repeated endlessly.
Followed to the government response
CIAO Clean tracks every registration until it is accepted or rejected, translates every remark into plain language, and freezes each movement as an immutable snapshot — audit-proof.
Built for your reality
Multiple legal entities in one organisation, teams with their own sites and managers, and registrations from other systems on the same contracts — in a single view.
04 Privacy
Registration without surveillance.
The app reads location only at the moment of checking in or out, to confirm that your worker is at a registered work location. No background tracking, no permanent monitoring — and the app says so to the worker in as many words. Position history has a short, configurable retention period.
A registration system you can also put in front of the works council.
05 The app
CIAO Mobile — made for the shop floor
One app for every worker: check in, check out, and see what was registered. No training needed, no manual on site.
What do the NSSO error codes mean? The full guide lives on ciao-connect.be — one catalogue for the whole CIAO family, never a copy per site.
06 The CIAO family
Already registering with another system?
Or do you also want to monitor what is already filed with the NSSO? CIAO Connect, our compliance monitoring for Check In and Out at Work, continuously checks every registration — including registrations that never went through CIAO.
One platform, three ways in: register with CIAO Clean, monitor with CIAO Connect.

- EU data hosting

08 Frequently asked questions
Answered straight
What is Check In and Out at Work (CIAO)?
Check In and Out at Work is the NSSO obligation to register workers' presence at the workplace in real time, against a declared work contract (DWC). It applies today to the cleaning sector, among others.
Does this work with multiple establishments or companies?
Yes. Multiple legal entities and teams with their own sites and managers sit in a single view, each with their own registrations and reports.
We already register with a time clock — what then?
Your existing registrations stay usable: CIAO Connect, our compliance monitoring for Check In and Out at Work, also reads registrations that other systems filed with the NSSO, on the same contracts.
What if a worker checks in or out outside the zone?
The registration is refused with an explanation in plain language, and edge cases are flagged transparently for the supervisor — never silently accepted.
Which languages does the app work in?
Available in 11 languages, including Arabic with full right-to-left support.
Does the app track my workers?
No. Location is read only at the moment of checking in or out, to confirm presence at a registered work location — no background tracking, and the app says so to the worker in as many words.
