Zero manual input
Hours registered via the Timer app land in your bookU Portal automatically & correctly encoded, ready to process. No double entry, no typos, no end-of-month stress.
Most SMEs are still on Excel, paper sheets, or memory. bookU’s Timer app changes that: your team clocks in, the right rules apply automatically, and validated performance data reaches your payroll partner in a few clicks. Accurate, compliant, zero manual work.

Hours registered via the Timer app land in your bookU Portal automatically & correctly encoded, ready to process. No double entry, no typos, no end-of-month stress.
Contracts signed digitally at clock-in, Dimona declarations filed automatically. And the bookU Timer app already meets the mandatory digital time registration requirement coming into force in 2027. Switch now and you’re ahead of the deadline.
Validated hours, processed with the correct performance codes, absence codes, and overtime rules, sent to your payroll partner in a few clicks. The “we’ll fix it on the next payslip” conversation stops here.

Download the bookU Timer app on a tablet or smartphone, place it in your business, and your team can start clocking in straight away. Available in the App Store and Google Play.
Employees find their name and enter their personal PIN at the start and end of every shift. Hours register live in your bookU Portal. No manual input, no errors.
Activate the optional camera alongside the PIN for extra certainty. Always know exactly who clocked in, even when you’re not on site.
Students and flexi-workers sign their contract digitally the moment they clock in via the Timer app. Never anyone on the floor without a signed contract.
Get a notification when an employee is late or forgets to clock out. A complete, real-time picture of who’s on the floor. Always.

Employees request leave or report sick directly via the bookU Staff app. They also check their holiday balance, overtime, and other counters, without asking you.
Check all leave requests in one clear overview in the Portal. Filter by employee, period, or absence type. Approve or decline in one click. No back and forth.
Configure the absence types that apply to your business: annual leave, ADV days, overtime counters, parental leave, sick leave, and more. Check the remaining balance per employee directly from their profile. Always up to date, always accurate.
Absences are automatically included in month-end performance processing and exported to your Payroll partner. No extra action required.

Compare registered hours with planned shifts at a glance, per employee, down to the minute. Correct manually where needed before sending anything to your social secretariat.
Review and approve performance per day, week, or month, whichever view fits your workflow.
Round time registrations according to your company agreements, or use the standard settings. bookU applies them consistently across your entire team.
After validation, time registrations are encoded automatically with the correct rules: overtime settings, performance codes, absence codes and more. Fewer errors, cleaner payroll.
All validated performances, encoded correctly, sent to your social secretariat in a few clicks. In the exact format their payroll system expects. Directly integrated.

Alexis runs Take Five, an espressobar in Ghent, the kind of small business that lives or dies by its team of students, flexi-workers, and weekend baristas. Before bookU, every new shift meant another Dimona declaration to file with the RSZ, another contract to chase, another late-night admin session that ended in dread. “I had literal nightmares about Dimonas,” he says. “Every student, every flexi-worker, another action I had to take. I thought I’d be chained to this for the rest of my life.”
Now, the moment someone clocks in on the Timer app, the contract generates and the Dimona files itself. Take Five’s biggest weekend used to be Alexis’s worst Saturday morning. Now it’s just a busy day.
Every workforce capability, connected. Grom planning to payroll prep.
