The problem isn't a shortage of systems. It's that the technician forgets to log the hours between the morning coffee break and the next job. Digital time registration on the construction site is about making logging easier than skipping it.

In short

  • Digital time registration from a phone gives the office real-time data, a direct link to invoicing and statutory working-time documentation, all in one flow.
  • The system has to work offline — many construction sites have poor coverage.
  • The most common mistakes are: too complex an app, missing check-in/check-out, and hours logged at the end of the week rather than as you go.
  • Automatic transfer to payroll and invoicing saves time and drastically reduces errors.

Why digital time registration from a phone?

Paper timesheets have two basic problems on the construction site. They aren't there — the slip gets left in the van, at the office, at home. And they're inaccurate — hours reconstructed on a Friday afternoon are rarely as precise as hours logged on the spot.

Mobile time registration solves both: the technician always has the phone on them, and check-in/check-out happens in the moment. The result is more precise data, fewer lost hours and an invoice draft that doesn't need manual copying.

On top of that, it covers the statutory requirement under the Working Environment Act (arbeidsmiljøloven) §10-7 — a written, up-to-date record of actual working time per employee. For more on this requirement, see Time registration for tradespeople: requirements, responsibilities and consequences.

Step by step: how a good workflow works

Morning: check in when work starts. The technician opens the app, picks today's job(s) and logs the start. Two taps, not a form.

During the day: switch jobs when you switch tasks. Jobs are billed per order — the technician switches to the right order when moving from installation to a service task. The system tracks who spends time on what.

Breaks: log breaks automatically or manually. Some systems deduct fixed breaks automatically; others let the technician log them. Whichever the method: breaks must be documented under the working-time rules.

End of day: check out when the day's done. Either manually, or the system closes the job automatically based on GPS movement (the technician leaves the construction site). The day's hours are totalled and sent to the office.

Friday: export to payroll and invoicing. The hours overview is ready for the employer to approve, to export to the payroll run and to transfer to the invoice draft — without manual copying.

What makes a time registration app good for the field?

Works offline. Mobile coverage on construction sites varies wildly. An app that syncs when there's a signal but doesn't crash without one is a basic prerequisite.

Links to the customer and the job number. Time registration per job — not just per day — gives you a basis for billing. Time without a job reference is time you can't bill.

Shows hours accumulated. The technician sees their own hours; the employer sees everyone's. The likelihood of an overtime breach is made visible, not discovered after the fact.

Simple UI. Three taps from opening to a logged hour. Any more than that and drop-off rises.

Integration with the accounting system. Export to Tripletex, Visma, Fiken — not manual copying. One manual transfer per job is one error opportunity too many.

The most common mistakes

Hours logged at the end of the week. Reconstruction is imprecise and unlawful under §10-7, which requires an ongoing record. Set up a reminder for morning logging.

No link to the job card. Hours without a project reference are useless for billing. The system should force a link.

The app doesn't work offline. The technician gives up and writes hours on paper — which never make it into the system.

The office doesn't see the hours until they're approved. The intermediary step leaves invoices sitting and waiting. Automatic notification when the technician finishes solves this.

Materials and special-order items

Time registration is half the picture. The other half is materials. A good app lets the technician log the materials used on the same job — whether by entering them manually, scanning a barcode or picking from a product library. That eliminates the classic argument three weeks later about which materials went on which job.

Frequently asked questions

Can we combine digital and paper-based time registration?

Technically yes, but it's a source of error. Hybrid systems require manually transferring paper hours into the digital record — exactly what you're trying to avoid. Pick one system and run it consistently.

What if the technician forgets to check in?

Most systems support retroactive logging: the technician enters the start and finish manually, and the employer approves. It's perfectly possible, but it raises the risk of errors. A push notification in the morning ("remember to check in") is the cheapest preventive measure.

Do we need GPS tracking in time registration?

Not a legal requirement. GPS-based check-in/check-out (geofencing) is a practical feature for businesses that want to verify the technician is actually on the job, but it's a management mechanism — not a legal requirement.

Summary

Digital time registration from a phone isn't an IT project — it's a change of routine. The technician logs start and stop where the job is, the system totals it and links it to the invoice, and the office exports it to payroll. The system has to work offline, link to the job card and have a low enough threshold that it actually gets used. Everything else is nice-to-have functionality, but not decisive.
