Growth is good news. But every new hire adds a layer of administrative complexity. Somewhere around the 25-employee mark, informal arrangements stop being enough: roster changes, leave requests, overtime monitoring and statutory obligations start to pile up. This is exactly the right moment to professionalise your processes, before the pressure becomes unmanageable.
Why 25 employees is a genuine inflection point
Belgian labour law draws several important lines based on company size: rules around union representation, works council obligations and the formalities required in your internal work regulations all shift as you grow. Add to that the mandatory electronic working-time registration coming in 2027, and the case for acting now becomes clear. It is far easier to implement a solid system while you still have room to breathe than to rush one in while simultaneously onboarding new colleagues.
The 38-hour week, daily and weekly overtime caps, and the rules governing part-time contracts are more nuanced than they first appear. If your time records still live in spreadsheets or paper sign-in sheets, there is a real risk that errors go unnoticed until a social inspection brings them to light. As explained in our guide on what a legally valid working-time record must contain, Belgian law requires server-stamped, tamper-evident entries. Spreadsheets simply cannot provide that guarantee.
Processes to get right before you scale
Before you cross the 25-employee threshold, it is worth tackling the following areas deliberately:
- Leave and absence management: Requests, approvals and registrations should flow through a single, auditable channel. A clean absence and leave-approval workflow prevents miscommunication and gives managers a real-time view of team availability.
- Overtime monitoring: Set clear rules and let the system alert you when employees approach legal limits. Belgian overtime rules are strict: there is a daily cap, an internal company cap and an annual ceiling. Manual tracking at scale is a recipe for costly mistakes.
- Department-level rostering: Once you have multiple teams, per-department scheduling becomes essential. A shared spreadsheet breaks down quickly when several managers are making simultaneous changes. A structured tool removes the ambiguity.
- Payroll accuracy: Time data that does not flow cleanly to your social secretariat leads to payroll errors that employees notice immediately. Your time-registration system should produce reliable, structured output rather than requiring manual re-entry.
Preparing for inspections and reporting obligations
As your headcount grows, the statistical likelihood of a labour inspection increases. Social inspectors request specific documents: attendance records, employment contracts and evidence of communicated schedules. If that information is scattered across folders, email threads and spreadsheets, a single inspection can cost you hours of frantic searching and increase the risk of formal sanctions.
A system that produces inspector-ready exports in minutes removes that anxiety entirely. Tikkit stores all time-stamp data server-side in a way that is both immutable and instantly retrievable, so you can present a complete, verifiable record whenever it is needed.
It is also worth ensuring your invoicing is in order as you scale. Since 1 January 2026, the B2B e-invoicing mandate via Peppol has been in force in Belgium. If you invoice other Belgian businesses, you are legally required to send and receive structured electronic invoices. For growing SMEs still relying on PDF invoices emailed as attachments, the time to regularise this is now, in parallel with sorting out your time-tracking processes.
Scaling with confidence, not chaos
The underlying principle here is straightforward. Systems that work well for ten people tend to crack under the weight of thirty. Waiting until things break means paying twice: once for the disruption and once for the emergency fix. Investing proactively in robust time registration, a clear leave policy and compliant invoicing processes means you grow more smoothly and present a more professional face to clients, employees and regulators alike.
Tikkit is built for Belgian SMEs making exactly this transition: moving from informal, good-faith arrangements to structured, legally compliant processes, without the cost and complexity of an enterprise platform.
