Linking time registration to payroll: process hours automatically
Every month, the same ritual. Collecting hours from Excel, a time clock or paper lists. Retyping them into your payroll system. Checking that everything adds up.
And then? Spotting an error anyway, right after the payroll run.
Sound familiar? Then it's time to link your time registration to your payroll. We'll explain how it works, what you gain and (more importantly) where things go wrong if you're not careful.
Why link the two?
Fewer errors. Less work.
When your time registration system talks directly to your payroll or social secretariat, manual entry disappears. Hours worked, overtime, night work, absences: everything flows automatically into payroll processing without you having to lift a finger.
In practice, this means:
- No more double entry (finally)
- Typos? Only if an employee clocks in wrong
- Faster payroll processing, sometimes days sooner
- Real-time insight into staff costs
- More time for real HR work instead of Excel acrobatics
Want to know how to prevent errors in hours registration? We've written a separate article on that.
For companies with a lot of variable hours (think hospitality, construction, retail), this isn't a luxury.
It's survival.
How does the link work technically?
Most modern time registration systems offer standard connections with Belgian social secretariats. There are two ways data gets exchanged.
API connection
A direct link between the two systems. Data is synced in real time or daily. This is the most seamless solution, but it requires both systems to be compatible. Don't work together? Tough luck.
File exchange
The time registration system generates an export file (often CSV or XML) that you import into your payroll. Less automated, but it works with virtually any system. Including that old social secretariat you've been working with for 15 years.
Which option is available? That depends on your current software. Most of the big players (Protime, GeoDynamics, Strobbo) have ready-made connections with SD Worx, Securex, Liantis, Partena and other social secretariats.
What exactly gets sent through?
A good connection sends more than just the "number of hours". A lot more.
Typically, this includes:
- Regular working hours per day
- Overtime (distinguishing voluntary from mandatory)
- Night and weekend hours
- Absences (illness, holidays, short leave)
- Cost centres or project codes
- Place of employment (relevant for commuting)
- Sometimes even breaks and travel time
The richer the data, the more accurate the salary calculation. Premiums for night work or weekend shifts are applied automatically, without anyone having to check them by hand. Saves your accountant a lot of headaches too.
The concrete benefits
Time savings
Depending on the size of your company, you save hours every month. No more Excel puzzles at the end of the payroll period. You can put that time into things that really matter.
Fewer errors
Manual entry is error-prone. A wrong figure, a forgotten overtime hour, an employee you skipped. With automatic transfer, the source is the time clock itself. If that's right, the rest is right too.
Faster processing
Payroll processing can start as soon as the hours period is closed. No waiting for paper or Excel files that are "supposed to be somewhere on the shared drive".
Better oversight
You get real-time visibility into hours worked and costs. Handy for budget monitoring and staff scheduling. And even handier when you suddenly have to explain why last month's wage cost spiked.
Compliance
Overtime, night premiums and other allowances are calculated automatically and correctly, in line with the applicable collective labour agreement (CLA) and your Joint Committee. Less risk of errors during NSSO (National Social Security Office) inspections. Because those always come at the worst possible moment.
Things to watch during implementation
Setting up a connection isn't plug-and-play. Sorry. Here are the things that usually go wrong (and how to avoid them):
Make sure the data is right at the source
Garbage in, garbage out. If employees don't clock in correctly, you'll get garbage out of payroll too. Invest in clear procedures and checks. Otherwise you're just automating your chaos.
Test thoroughly before go-live
Run at least one payroll period in parallel: both via the old method and via the connection. Compare the results.
Only go live when everything adds up. Not "mostly" adds up. Really everything.
Involve your social secretariat early in the process
They know the technical requirements and can help with mapping the data. Some secretariats have their own implementation teams for connections. Call them before you buy a time registration system, not after.
Plan for exceptions
Not everything fits into a standard connection. Think of after-the-fact corrections, manual adjustments or employees who work at multiple locations. Make sure there's a process for exceptions. Otherwise you'll keep retyping hours anyway (which was exactly what you wanted to avoid).
Popular combinations in Belgium
A few commonly used connections we come across in practice:
| Time registration | Social secretariats |
|---|---|
| Protime | SD Worx, Securex, Liantis, Acerta |
| GeoDynamics | Liantis, Securex, Accuria, Group S, Partena |
| Strobbo | SD Worx |
| GPS-Time / Emprova | Various, via API or file exchange |
Most systems are flexible. When in doubt, request a demo or check with your current supplier which integrations are available.
Voluntary overtime: 2026 update
Good to know: from 1 April 2026, the voluntary overtime scheme gets a permanent place in Belgian labour law. This means your time registration has to be able to distinguish between regular overtime and voluntary overtime (the "relance hours").
Check whether your system supports this. If not? Then you'll have to track it manually.
Exactly what you wanted to avoid.
When is a connection worthwhile?
Not every company needs an advanced connection. A rule of thumb:
Fewer than 10 employees with fixed hours Manual entry is often still workable. It might cost you an hour a month.
10 to 50 employees or variable hours A connection saves significant time and errors. This is where it starts to get interesting.
50+ employees A connection is virtually indispensable for efficient payroll processing. Otherwise you're collecting hours full-time.
Do you work with a lot of temporary staff, flexi-jobbers (flexi-job: a form of secondary employment with favourable tax and social security treatment) or agency workers? Then automation matters even more. The admin per employee is limited, but the volume makes it labour-intensive. Ten flexi-jobbers per weekend? That's already 40 contracts a month. Check out our checklist for temporary employees so you don't forget anything.
At Recruit, we process thousands of temporary workers every month. A good time registration connection is essential for correct and timely pay.
Steps to get started
Want to link your time registration to payroll? These are the steps:
1. Take stock of your current situation Which time registration system do you use? Which social secretariat or payroll system?
2. Check the available connections Ask both suppliers which integrations are possible. Do this before you decide anything.
3. Decide what you want to send through Just hours? Or also project codes, cost centres, places of employment? The more complex your data, the longer the setup.
4. Plan the implementation Set aside time for setup, testing and training. Count on at least a month from first conversation to go-live.
5. Test and fine-tune Run in parallel until everything adds up. Resolve the exceptions.
6. Go live and monitor Keep checking extra carefully during the first few months. Edge cases you didn't foresee always pop up.
In short
Linking time registration to payroll eliminates manual work and reduces errors. Most Belgian time registration systems offer standard connections with social secretariats. The investment in setup pays for itself quickly, especially with variable hours or larger teams.
Still retyping hours from Excel?
It doesn't have to be that way.

Frequently asked questions
Does every time registration work with every social secretariat?
Not automatically. Most big players have standard connections, but always check this in advance. When in doubt, file exchange (CSV/XML) can be an alternative. Less sexy, but it works.
What does such a connection cost?
This varies widely. Some connections are included in your time registration subscription, others require a one-off setup cost or a monthly fee. Ask both suppliers for quotes. And keep asking, because the first price is rarely the full price.
Can I send absences through automatically too?
Yes, most connections support this. Illness, holidays and other absences are sent along to payroll. Saves you manual work again.
What if there are errors in the time registration?
Corrections are always possible, but it's more efficient to fix errors at the source. Put good procedures in place around clocking in and check the data before closing the payroll period. Because after the payroll run, you're too late.
