1. Introduction

Time tracking is a topic that affects businesses of every size throughout the EU. From an employer’s perspective, registering working hours is essential for complying with labour regulations, properly documenting employees’ working hours, and ensuring accurate wage payments. For employees, proper time tracking offers a clear overview of their own working hours, potential overtime, time off in lieu, and more. In this article, we will explore what time tracking actually is, why it is important, and how to approach it in a way that benefits both the business and its workforce. We will also highlight the growing focus on mandatory time tracking under EU regulations and what it means for employers operating within the European Union.

This article is intended as a comprehensive guide, covering everything from the basic purpose of time tracking to deeper considerations like working time directives, compliance requirements, documentation obligations, and absence management. Many companies already have some form of time tracking solution in place, but others have yet to implement a suitable system—often because of uncertainty about the regulations, confusion over which technology to use, or concerns about additional administrative work. Here, you’ll find essential information to help you make an informed decision.

2. What is time tracking and why is it so important?

In its simplest form, time tracking means keeping a record of working hours—when employees clock in, when they take breaks, when they clock out, and in some cases which tasks or projects they are working on throughout the day. This can be done manually (e.g. paper sheets or spreadsheets) or digitally via a time tracking system.

Time tracking as the foundation for business operations

• Compliance with working time rules: Working hours must be documented to ensure compliance with EU and local labour laws, including daily and weekly rest periods and maximum working hours.
• Financial clarity: Accurately recorded working hours ensure correct wage payments, including evening, weekend, or overtime supplements, and enable precise billing for client-facing work.
• Workplace well-being: A detailed overview of working hours can highlight potential stress or burnout risks if employees work excessive hours, allowing for early interventions to safeguard health and productivity.

Time tracking is a cornerstone of Workforce Management (WFM). It is nearly impossible to plan capacity, projects, or resources effectively without knowing how time is being spent.

3. Time tracking – Is it a requirement by the EU?

Growing attention has been given to mandatory time tracking across EU Member States following various directives and legal interpretations, most notably the 2019 ruling from the European Court of Justice (ECJ) clarifying that employers must set up an objective, reliable, and accessible system for recording each worker’s daily working time. While the specific dates and requirements for national legislation can vary by country, the essence is clear: businesses need a system or method in place to log their employees’ working hours in a manner that complies with both EU directives and national labour laws.

Why is the legal aspect so important?

• Compliance with the law: Regardless of your company’s size, time tracking is shifting from best practice to legal obligation in many jurisdictions across the EU.
• Fairness for employees: The overarching goal is to prevent situations in which employees work more than the allowed hours and to ensure they receive the wages, supplements, holiday pay, and potential time off in lieu (TOIL) they have earned.
• Financial accuracy: Proper documentation of hours worked makes it easier to bill clients appropriately, monitor overtime, and avoid payroll errors.

The core of these obligations is that employers must be able to prove compliance with all relevant working time rules. It’s not enough to simply “keep an eye on things” or “trust people”—businesses must be able to verify and demonstrate that everyone’s hours are recorded correctly. This usually means having a secure, user-friendly system that gives a comprehensive overview of all relevant data. If you already have a time tracking system, ensure that it meets current EU-wide standards and any national requirements, including secure storage and archiving for auditing purposes.

4. What's behind the EU's mandatory time tracking rules?

Working time regulations in the EU
The EU Working Time Directive (2003/88/EC) provides the framework for maximum weekly working hours, rest breaks, and statutory paid leave. Each Member State implements these rules in its own way, leading to variations in how companies are legally obligated to track and document working hours. Recent developments stemming from ECJ rulings have given Member States a clearer impetus to mandate explicit time-tracking solutions.

No longer optional but compulsory
Previously, time tracking was often recommended as a best practice for efficient operations and cost management. With newer legal clarifications, it is becoming a statutory duty across much of the EU, making it vital for businesses to adopt a reliable and transparent approach.

Backed by court precedent

In 2019, the European Court of Justice (ECJ) ruled that EU member states must require employers to set up objective, reliable, and accessible systems to record employees’ daily working time. This landmark decision reinforced the need for transparent time-tracking to uphold workers’ rights under the Working Time Directive, particularly to protect employees from excessive hours and to ensure fair rest periods and compensation.

"Time tracking provides clarity. It ensures fairness in payroll, optimizes workforce allocation, and prevents burnout. With accurate data, businesses can reduce inefficiencies and improve productivity while giving employees transparency and control over their time."

5. What are the financial benefits of time tracking?

Time tracking isn’t just about staying compliant with the law – it’s the foundation for a more profitable and efficient workplace. When digital time tracking is integrated into a Workforce Management (WFM) system, businesses can unlock measurable financial gains and significantly streamline administrative processes.

In an internal analysis of a department with 25 employees, we identified a time saving of 703 hours per month – that’s around 88 working days. Over the course of a year, this adds up to 1,055 working days that were previously spent on manual tasks like recording hours, holidays, absences, shift swaps, time off in lieu, and payroll calculations. That time is now freed up for more strategic, value-adding work – things like budget control, resource planning, financial follow-up, and strategic HR efforts.

From a financial perspective, this equates to roughly €12,700 in monthly savings just from reduced payroll costs linked to routine admin and error handling. On top of that, we’ve seen an overall efficiency improvement of up to 15%, thanks to better data quality and less manual input.

The direct financial benefits of digital time tracking within a full WFM setup include:

• Streamlined payroll
  Automatic validation of hours worked reduces errors and disputes, saving time and resources in both HR and payroll teams.

• Accurate invoicing
  For businesses that invoice by the hour, digital tracking ensures accurate reporting of time spent, maximising revenue and providing solid invoicing data. For instance, a manufacturing firm can record the exact time spent on each customer order, improving billing accuracy and cutting losses from underreported hours.

• Less admin work
  Integration with payroll, HR, and ERP systems removes manual tasks like correcting input errors, managing absences, or rounding off hours manually.

• Smarter resource management
  Greater visibility over employee time allows for better tracking of budgets, wage percentages, and staffing levels, giving finance teams the tools for more effective decision-making.

• Strategic HR insights
  HR departments can proactively monitor key metrics like absence rates, compliance with labour laws and agreements, and catch issues early, lowering the risk of costly personnel issues, internal conflicts, or fines.

A proven overall efficiency boost of up to 17% shows that digital time tracking, when supported by a full WFM system, isn’t just a tool – it’s a smart, strategic investment that brings clear financial value and strengthens your business’s competitive edge.

6. Building trust: Why does proper time tracking benefit employees?

Employees invest a significant part of their lives at work and expect transparency about overtime, TOIL, holidays, and other aspects of employment. A system that accurately records working hours enhances clarity and peace of mind:

• Eliminates uncertainty: Clear records of attendance, weekend shifts, or overtime.
• Ensures timely and correct pay: Avoids payroll errors and frustration.
• Provides documentation: Allows employees to easily demonstrate their hours and entitlements if disputes arise.

Time tracking is not just a management tool; it serves the workforce as well, reducing misunderstandings and fostering a culture of openness.

"A strong time tracking system builds trust and accountability. Over time, it leads to better labour cost control, improved compliance, and higher employee satisfaction. It also helps companies spot trends, refine processes, and create a healthier work environment."

7. Getting started with time tracking

We have now covered the key points: it’s becoming mandatory in many countries, it helps the bottom line, and it fosters employee trust. But how do you actually implement a good time tracking solution? Let’s examine manual versus digital approaches, integration with payroll software, and more.

Manual versus digital methods

• Manual: Employees log their hours on paper or spreadsheets, which then get entered into a payroll system.
• Pros: Low initial cost, minimal technical requirements.
• Cons: High risk of errors, time-consuming administration, hard to gain a complete overview.

• Digital: Employees record hours via mobile apps, online portals, or terminals, and all data flows into a central system.
• Pros: Automation, reduced error rates, real-time overview, easy integration with payroll.
• Cons: Requires investment in software and training.

In most EU countries, a digital approach is increasingly preferable and often necessary for meeting the detail and security standards required by law.

What can a good time tracking system do?

• User-friendly: Log hours in real time via mobile app or web browser.
• Project tracking: Assign time to specific tasks, clients, or departments.
• Absence management: Track holidays, sickness, parental leave, etc.
• Overtime & TOIL: Calculate overtime automatically, reducing manual errors.
• Integration: Sync seamlessly with payroll, finance, or ERP systems.
• Reporting: Generate insights on time usage, overtime patterns, and absences.
• Scalability: Handle anything from a few employees to thousands.

8. Managing absences, overtime, and TOIL

Leave of absence

Ensuring compliance with working time rules and labour standards includes registering not only when people work but also when they do not:

• Sickness: Record start and end dates of sickness absence, ensuring correct rules for pay and any applicable state benefits.
• Holidays: Track accrued holiday entitlements, paid and unpaid leave, and clearly mark approved holiday periods.
• Parental leave: A more complex category involving both EU legislation and local regulations for maternity, paternity, and parental leave.
• Special leave: Covers compassionate leave, bereavement, or jury duty, ensuring employees can take necessary time off with the correct documentation.
• Unpaid leave: Any personal or extended leave periods outside standard entitlements that need to be tracked for payroll accuracy.

A robust system typically sets up categories for different types of absence so both administrators and employees can easily stay on top of remaining leave balances, holiday pay, or any associated costs.

Overtime and TOIL

Overtime can be challenging if recorded incorrectly. By using a modern digital system, it becomes simpler to:

• Automate alerts: Notify managers and employees when maximum daily/weekly hours are about to be exceeded.
• Apply correct rates: Automatically factor in evening or weekend pay differentials.
• Manage TOIL: Ensure time off in lieu is tracked properly so employees receive the rest days owed to them.

A well-structured workforce management system takes the guesswork out of handling absences, overtime, and TOIL. By automating compliance checks, tracking leave entitlements, and ensuring correct pay calculations, businesses can maintain both operational efficiency and employee well-being—all while staying compliant with local labor laws and collective agreements.

9. Implementation: How to set up a time tracking system

Setting up a time tracking system requires careful planning to ensure it aligns with business needs, integrates smoothly with existing workflows, and is easy for employees to use. A structured approach helps maximize efficiency and compliance from day one.

Needs assessment

Choosing the right time tracking solution begins with understanding your organization’s specific requirements. Key factors to evaluate include:

• Company size
  How many employees will need to use the system, and how are they distributed across departments, teams, or locations?

• Organisational structure
  Do you require segmentation or grouping – for example, by region, business unit, or job role – that involves different rule sets or configurations?

• Industry
  Are there any collective agreements or specific regulations you need to account for? This could include rules around overtime pay, holiday entitlement, rest periods, or industry-specific compliance requirements that the system must support.

• Integrations
  What existing systems (such as payroll, ERP, or HR platforms) does your time tracking need to integrate with?

• Mobility
  Do employees work remotely or on the move, requiring mobile access to log time wherever they are?

• Work time complexity
  Does your organisation have complex scheduling rules, such as flexitime, shift work, or overtime, that the system must automatically manage?

• Reporting and data analysis
  What kind of reporting do you need? For example, budgeting, payroll data, or absence tracking?

Onboarding and training

Once the system is selected and set up, the next step is making sure it’s introduced properly to both administrators and employees. A smooth onboarding process is essential for ensuring the system is used correctly and consistently. Focus on the following:

• Create user profiles
  Make sure everyone has access and the right permissions in both the system and the app.

• Tailor the user experience
  Show relevant features based on roles – for example, team leads, hourly workers, or salaried staff.

• Walk through key workflows
  Demonstrate how to log hours, request leave, and approve timesheets.

• Offer hands-on training
  Use demos, short guides, or interactive workshops to make the process clear and easy.

• Provide support and follow-up
  Have a support plan in place and check in during the first few weeks to ensure everything’s running smoothly.

10. Integration with payroll: Avoid double-entry

Integrating a time tracking system with payroll eliminates redundant work, reduces errors, and saves significant administrative time. Many employers underestimate how much efficiency they gain by automating this process.

Integration benefits

By linking time tracking with payroll, businesses can:

• Data transfer: Employee hours are submitted directly for payroll processing, ensuring accuracy and compliance.
• Minimise errors: Eliminates manual re-keying, reducing costly payroll mistakes and saving an estimated 3.6 workdays per month per payroll worker.
• Save time: Each payroll worker can save 29 hours per month, adding up to 43 workdays saved annually.
• Boost efficiency – Automating payroll processes contributes to an overall 10.5% efficiency gain, allowing payroll teams to focus on strategic tasks rather than data entry.

Two-way communication

Advanced payroll integrations can also pull in relevant data—such as up-to-date holiday balances or TOIL accruals—creating a seamless, real-time ecosystem for all time-related information.

By streamlining payroll processes, companies significantly reduce administrative burdens and increase overall productivity, making payroll automation a highly effective investment.

11. Documentation and compliance: Meeting all requirements

Ensuring proper documentation of working hours is not just about efficiency—it’s a legal necessity. Under EU directives and most national laws, businesses must maintain detailed records to comply with labour regulations, avoid penalties, and uphold fair working conditions.

What needs to be documented?

Under EU directives and most national laws:

• Accurate record of start/end times (or total hours per day).
• Archiving: Data typically must be retained for several years in case of inspections or audits.
• Detailing: Some industries may need to show which tasks were performed (e.g. to verify billable hours or for payroll/tax controls).

Consequences of non-compliance

Failing to document working hours properly can lead to serious consequences:

• Financial penalties: Authorities can impose fines for failure to comply.
• Reputational damage: Breaches can harm an employer’s credibility with employees and the public.
• Legal action: Workers or unions may pursue claims if working hours are deemed unfair or incorrectly documented.

Why did time-tracking become a requirement?

12. Use cases across service industries

Retail
With varying opening hours and seasonal employees, a clear digital overview helps quickly adjust staffing, avoid errors with weekend or overtime supplements, and seamlessly transfer hours to payroll.

Hospitality
Hotels and restaurants often have diverse pay rates for different roles and shift times. Time tracking ensures all shifts are appropriately documented, correct allowances are paid, and staffing is optimised for busy periods.

Care and clinical services
Night and weekend shifts, on-call duties, and strict rest requirements make accurate time tracking crucial. This ensures patient or client coverage and compliance with local labour regulations.

Manufacturing
It might not always be viewed as a “service” in the traditional sense, but production involves multiple shifts, possibly union agreements, and occasional overtime. Clear record-keeping is vital to optimise workflow and comply with employee welfare standards.

Entertainment
Project-based work, irregular hours, and rotating teams are the norm. Good time tracking allows management to see exactly where resources are deployed, anticipate pinch points, and ensure fair compensation.

Logistics and warehouses
Warehouses and transport companies see changing workloads based on seasonal peaks and campaigns. Digital systems let you see at a glance whether you need more staff and track any overwork.

Housing associations
Caretakers and property managers often split their hours across multiple sites. Time tracking documents how many hours are spent where, helps plan holidays, and keeps overtime transparent.

A common thread unites these industries: service, flexibility, and transparency. When you record hours consistently and clearly, it’s far easier to explain how overtime pay is calculated, how leave is administered, or how to rotate staff in response to demand.

13. Time tracking as a tool for improvement

Time tracking isn’t just about knowing when employees clock in and out – it can also be a powerful tool for resource management and optimising internal processes. When data on working hours is collected continuously, it opens the door to a more advanced approach to Workforce Management (WFM).

For example, managers can use real-time reporting to identify which projects or departments need extra support – and who has the capacity to help. This makes it easier to reallocate staff across teams, ensuring workloads are balanced and potential bottlenecks are avoided.

At the same time, this level of insight allows you to compare planned hours with actual time spent, giving you the opportunity to constantly refine and improve your planning processes.

And when time is tracked in more detail – for instance, by task or project – it provides a clearer view of productivity and resource usage. This makes it easier to make informed long-term decisions around staffing, team structure, and priorities.

In this way, time tracking becomes far more than just a documentation tool – it turns into a proactive management resource that supports strategic planning, operations, and, ultimately, employee wellbeing.

14. Introducing or upgrading a time tracking system

Rolling out a new time tracking system – or upgrading an existing one – can be a significant change for both management and employees. But with solid planning, clear communication, and a gradual approach, the transition can be made smoother, ensuring the system supports both business needs and employee well-being.

1. Leadership support

Make sure senior leadership is involved from the outset. Their backing gives the project legitimacy and reinforces that this isn’t just a technical upgrade – it’s a strategic priority.
Clarify the purpose of the new system: Is it mainly about legal compliance, ensuring accurate pay, or improving planning and resource management?

2. Assess needs and current processes

Begin by mapping out how time is currently recorded: What systems or routines are in place today, and where are the biggest challenges?
Consider any collective agreements, seasonal work patterns or unique payroll structures that the new system must accommodate.

3. Early employee involvement

Involve representatives from different departments and job roles to ensure the system works well for everyone.
Make room for questions and feedback. Some employees may feel sceptical or concerned that time tracking will feel like increased surveillance.

4. Pilot and system setup

Test the system in a smaller part of the organisation before rolling it out company-wide. This gives you the chance to fine-tune the setup and resolve any issues.
Ensure things like overtime rates, absence types and holiday rules are configured correctly from day one, so calculations are accurate from the start.

5. Training and communication

Offer short workshops or simple guides to help staff learn the system – both on desktop and mobile.
Reinforce the message: The aim is to make things easier for everyone, to ensure fair and accurate pay, and to meet new legal requirements around working hours.

6. Ongoing follow-up and adjustment

Keep an eye on how the system is used day to day. If challenges arise, address them quickly to avoid frustration or loss of trust.
Consider running a review after three months: What adjustments could improve workflows or make the system even more effective?

Common pitfalls—and how to avoid them

• Overcomplicated systems
  If it takes 10 clicks to log a break, employees will find ways around it. Choose a simple, intuitive system.

• Lack of training
  Throwing a new system at staff without an introduction leads to mistakes – and frustration. Proper onboarding is key.

• Incorrect rule setup
  Overtime, bonuses and collective agreements must be configured properly. If not, payroll errors are inevitable.

• Half-hearted implementation
  To stay compliant, the system must be embedded in daily operations. If some departments don’t use it, you’re still at risk of breaching working time laws.

15. What is the future of time tracking?

In an era of flexible work arrangements, international teams, and increasing digitalisation, effective time tracking is more important than ever. New legal obligations are just one piece of the puzzle: companies that leverage modern technology to create transparency and data-driven practices can gain a significant competitive edge.

We are already seeing how intelligent solutions fully integrated into HR and Workforce Management systems make it easier to plan capacity, spot early signs of overload, and analyse productivity. Cloud-based and AI-driven technologies allow large-scale real-time data collection across multiple locations and time zones. The result is not just correct payroll and compliance but also a more flexible and dynamic work culture that supports remote work and asynchronous collaboration.

Striking the balance between advanced tracking and respect for privacy will become increasingly crucial. Successful organisations are those that foster a culture where time tracking is seen as a tool for fair wages, improved well-being, and responsible labour practices. Over the longer term, the historical data you collect will form a vital foundation for strategic decision-making, new business development, and strong positioning in a constantly evolving jobs market.

And perhaps most importantly: the sooner you start collecting reliable data on working hours, the sooner you'll gain valuable insights that can help optimise operations and resource use. Over time, this historical data becomes a vital foundation for making better decisions, developing new business areas, and maintaining a strong position in a rapidly changing job market.

In other words, time tracking isn’t just a legal requirement – it can become one of your company’s most powerful competitive advantages.

"Time tracking is becoming more automated, real-time, and employee-centric. AI and integrations will make it seamless, reducing admin work while improving accuracy. Future systems will focus on flexibility, fairness, and better work-life balance."

15. Wrapping up 

As flexible work patterns, remote employment, and complex employment contracts proliferate, a robust and compliant time tracking system is essential. EU rules on working time have shifted from “nice to have” to “legally required” in many jurisdictions. If you don’t already have a solution, it’s wise to act swiftly to meet both present and forthcoming requirements; if you do have a system, ensure it meets modern standards.

Beyond avoiding penalties, implementing a well-structured, digital time tracking solution yields multiple benefits: streamlined billing, payroll accuracy, easier planning, reduced admin tasks, and, above all, a workforce that feels supported and fairly treated. In other words, it’s a simple yet powerful way to add value across your entire organisation—from the frontline employees to the leadership team.

With reliable time tracking, you’ll be well equipped for the challenges of tomorrow’s workplace, whether that involves new forms of employment, stronger legal requirements, or tougher market competition. And most importantly, you’ll demonstrate responsibility towards both your employees and your company’s financial health at a time when transparency and compliance matter more than ever.
