Why time tracking in field service causes so many problems for businesses
In the office, time tracking is straightforward: employees arrive in the morning, clock in, take a lunch break, and clock out in the evening. In field service, this does not work. Here, the working day begins in the car, the first assignment is at a customer's premises, the second is on a construction site, and in between there is driving, phone calls, and documentation. When exactly did working time begin? What counts as travel time, and what counts as on-site time? And how does one prove all of this when the employee never sets foot in the office all day?
These are the exact questions many companies face – and many still have no clean answer. The result: time sheets are filled in from memory on Friday afternoon, travel times are estimated as flat figures, project assignments are incorrect, the office chases people every week, and payroll works with unreliable data.
Yet the direction is clear: under EU case law, time tracking is required for all employees – regardless of whether they work in the office, at a customer's site, or on the motorway.
What the law means specifically for field service
In the EU, the Court of Justice ruled on 14 May 2019 (C-55/18) that employers must set up an objective, reliable and accessible system for recording the daily working time of each worker. This also applies to field service employees, service technicians, sales representatives, and all other staff who regularly work outside the office.
How the obligation is implemented in detail – which data must be recorded, and which exceptions exist, for example for staff who largely organise their own working hours – is governed by national law and collective agreements in each country.
Important for field service businesses: Working time rules do not distinguish between office work and field service. The documentation obligation applies to the technician at the customer's site in exactly the same way as to the desk clerk in the office. Violations of recording obligations can be punished with fines under national law – and in the event of an inspection by the authorities, the records must be complete and readily available.
What exactly must be documented
For each working day of a field service employee, the following data is typically recorded:
- ✅ Start of work – the point in time at which the employee commences their work activity
- ✅ End of work – the point in time at which the work activity is concluded
- ✅ Breaks – the rest breaks taken (EU law requires a break when the working day exceeds six hours; its length is set by national law or collective agreements)
- ✅ Total duration – the actual working time performed during the day
In addition, it is recommended that field service businesses also record travel times (as working time or separately), project assignments, and deployment locations – not because the law explicitly requires it, but because this forms the basis for accurate client invoicing, post-calculation, and resource planning.
Why paper and Excel fail in field service
At first glance, it seems simple: the employee writes down the start time on a time sheet in the morning and the finish time in the evening. In practice, this almost never works – and here is why:
- ❌ Time sheets are not completed in real time. No technician pulls a piece of paper out of their pocket at the customer's site. Times are entered from memory in the evening – rounded, estimated, and often inaccurate.
- ❌ Travel times are given as flat figures. Was the drive to the customer 35 or 50 minutes? By Friday, nobody remembers. The result: travel times are over- or under-estimated.
- ❌ Project assignments are missing. The time sheet shows eight hours – but not how many of those apply to Client A, Project B, or Order C. Without assignment, no post-calculation is possible.
- ❌ Time sheets get lost or are illegible. In the service vehicle, on the construction site, in the rain – paper does not survive everyday field service.
- ❌ The office spends hours on follow-up work. Chasing missing entries, deciphering illegible figures, checking Excel formulas, copying data together for payroll. This effort grows with every field service employee.
- ❌ Weak proof during official inspections. Paper slips are often incomplete, filled in after the fact and easy to alter. Without complete, timely records, there is no solid basis in the event of an inspection.
Time sheets vs. app: an honest comparison for field service
| Criterion | Time sheets / Excel | Digital time tracking app |
|---|---|---|
| Recording accuracy | Low – from memory | ✅ High – real time via smartphone |
| Travel time separation | Manual – often forgotten | ✅ Separate booking with one tap |
| Project assignment | Usually missing entirely | ✅ Assign directly when clocking in |
| Location verification | Not possible | ✅ GPS or NFC when clocking |
| Offline capability | Yes (pen and paper) | ✅ Depends on the app – Jobilino stores clock-ins offline and sends them later |
| Proof during inspections | Difficult to prove | ✅ Complete, digital documentation |
| Office effort | High – chasing, retyping, checking | ✅ Much lower – data arrives ready to use |
| Post-calculation possible | Only with great effort | ✅ At the touch of a button by project |
| Cost | Hidden: rework, errors | A few euros per employee/month (Jobilino Basic: €5.99, less for larger teams) |
What a good time tracking solution for field service must be able to do
Not every time tracking app is suitable for field service. Solutions built for office work or agencies fail to meet the requirements of mobile teams. Here are the features that a field service time tracking solution absolutely must have:
1. Mobile app with offline functionality
Field service employees work in places without a stable network connection – in basement rooms, on construction sites, in rural areas. The app should reliably capture bookings even without a network and transfer them automatically once a connection is restored. With Jobilino, clock-ins are stored on the device and sent as soon as a connection is back.
2. Project assignment when clocking in
When starting their working time, the employee must be able to select directly which client, project, or order they are working on. Only in this way are clean project times created that can be used for post-calculation, client invoicing, and quote preparation. A simple start-stop time clock is not sufficient in field service.
3. Travel time separation
In field service, travel time makes up a significant part of the working day. Good solutions allow travel times to be booked separately – distinct from productive on-site time at the customer's premises. This is not only relevant for invoicing, but also for route planning and tour optimisation.
4. Location verification – GPS or NFC
For many field service businesses, proving that an employee was actually at the customer's site is business-critical. Two technologies help with this:
- GPS: Records the location when clocking in and out. Advantage: works anywhere with mobile coverage. Disadvantage: data protection concerns, less precise indoors.
- NFC: The employee holds their smartphone against an NFC tag at the customer's premises or deployment location. Advantage: proves physical presence at the exact spot, more data-protection-friendly than GPS, works offline. Disadvantage: NFC tags must be installed in advance.
For cleaning sites and fixed deployment locations, NFC is generally the better choice. For changing customer addresses without pre-installed tags, GPS is the more practical solution. The best software offers both.
5. Simple operation without training
Field service employees are technicians, tradespeople, service staff – not IT experts. The app must be simple enough to use immediately without any training. One tap on Start, one tap on Stop, select project – done. If the app is more complicated than the time sheet, it will not be used.
6. Multilingual support
Many field service businesses employ international teams. An app available only in German excludes part of the workforce. Good solutions offer the interface in multiple languages – ideally German, English, Serbian, Croatian, Albanian, Hungarian, Slovak, and Turkish.
7. Reports and export
In the end, the question is: what value does the recorded time bring to the office? The answer must be: ready-made reports. Monthly overviews per employee, hour breakdowns per project, exports for payroll – at the touch of a button, without manual collation.
GDPR note: If your time tracking solution processes GPS data, employees must be transparently informed about the type, scope, and purpose of data collection. GPS tracking is only permitted during active working hours – recording outside working hours is not allowed. Where employee representatives exist, national law may require their involvement. NFC location records are less sensitive from a data protection perspective because they only prove presence at a specific point and do not create movement profiles.
Typical field service scenarios and how time tracking works there
Depending on the industry and working method, different requirements arise for time tracking in field service. Here are the most common scenarios:
Service technicians with multiple customer assignments per day
The technician opens the app in the morning, selects the first customer, and begins the journey. At the deployment location, they switch to on-site time. After the appointment, they book the drive to the next customer. In the evening, the system shows exactly: 45 minutes travel, 2.5 hours at Client A, 30 minutes travel, 3 hours at Client B, 20 minutes travel back. The office immediately has the data for client invoicing and payroll.
Cleaning staff with changing sites
Cleaning staff work at several sites each day – office buildings, medical practices, residential complexes. An NFC tag is installed at each site. The employee holds her smartphone against the tag and is clocked in. When leaving the site, she holds it against the tag again. The system documents completely: who was at which site and when? Ideal for providing proof to clients.
Installation workers on construction sites
Installation workers and tradespeople often work an entire day on one construction site – but not always the same one. Working time must be assigned to the correct construction site, the correct trade, and the correct client. If the site is selected directly when clocking in, every hour ends up on the right job – without filling in gaps at the weekend.
Sales representatives with customer appointments
In sales, working hours are often difficult to define clearly – customer meetings, travel, phone calls, quote preparation. A good field service time tracking solution allows bookings under various categories: customer visit, travel, internal work. This gives management visibility into how much sales time is actually spent with customers.
Checklist: finding the right time tracking solution for your field service
Not every solution is suitable for every field service operation. Check the following points before making your selection:
- ✅ What works without a network – for example clocking in via NFC tag in basements, on construction sites, and in rural areas?
- ✅ Can working times be assigned to a project, client, or order directly when clocking in?
- ✅ Is there a separation between travel time and on-site time?
- ✅ Does the app offer location verification – via GPS, NFC, or both?
- ✅ Is the app multilingual – for international teams?
- ✅ Can foremen or team leaders see who in the crew is currently clocked in?
- ✅ Are there ready-made exports for payroll and client invoicing?
- ✅ Is the app simple enough for employees to start using immediately without training?
- ✅ Is data stored in a GDPR-compliant manner on European servers?
- ✅ Can I test the solution free of charge and without obligation?
Conclusion: time tracking in field service is solvable – with the right app
Time tracking in field service is not a special problem requiring exceptional creativity – it is a solved problem. Modern apps record times in real time, assign them to projects, separate travel times from on-site times, and deliver ready-made reports to the office for payroll and invoicing.
The difference between a business that battles with time sheets every week and a business that has its field service hours cleanly under control comes down to a single decision: implementing the right time tracking app. Not next month. Not next quarter. Now.
Implementation typically takes just a few hours. Employees need no training. And the results – fewer queries, clean data, fast payroll preparation – are noticeable from day one.
