A timesheet is a record that tracks the hours an employee works during a given period — typically a day, week, or pay cycle. Originally paper forms filled in by hand, timesheets now range from spreadsheet templates to integrated software that feeds directly into payroll systems. They remain the foundation of accurate pay, compliance, and workforce planning.
Whether you run a five-person startup or a 500-person enterprise, the principle is the same: if you cannot account for hours worked, you cannot calculate pay accurately, comply with working time laws, or understand where labour costs go.
Key Takeaways
- A timesheet records hours worked per employee over a defined period, forming the basis for payroll and compliance.
- Common types include paper, spreadsheet, punch-clock, biometric, and cloud-based digital timesheets.
- UK employers must comply with the Working Time Regulations 1998, which cap average weekly hours at 48 unless workers opt out.
- Digital timesheet systems reduce payroll errors, automate overtime calculations, and create audit trails.
- Choose a timesheet system based on team size, remote/hybrid needs, integration requirements, and compliance obligations.
What Is a Timesheet?
A timesheet captures when an employee starts work, when they stop, and any breaks taken in between. The resulting data feeds into payroll, project costing, and compliance reporting. In its simplest form, a timesheet answers one question: how many hours did this person work?
For salaried employees, timesheets may seem redundant — but they still serve critical functions. They verify compliance with the UK Working Time Regulations, provide evidence in pay disputes, and help managers track project allocation. For hourly workers, timesheets are non-negotiable — every unrecorded hour is either unpaid labour or untracked cost.
Types of Timesheets
Different organisations need different approaches. The right choice depends on your team size, work patterns, and budget.
| Type | How It Works | Best For | Limitations |
|---|---|---|---|
| Paper timesheet | Handwritten daily/weekly form | Very small teams, casual workers | Prone to errors, hard to aggregate, no audit trail |
| Spreadsheet | Excel or Google Sheets template | Small businesses with simple needs | Version control issues, manual formulas, no automation |
| Punch clock / time clock | Employee swipes a card or badge at entry/exit | Factories, warehouses, fixed-site operations | Rigid, no remote support, buddy-punching risk |
| Biometric | Fingerprint, facial recognition, or iris scan | Large on-site teams needing tamper-proof records | Privacy concerns, hardware cost, GDPR considerations |
| Cloud-based / digital | Browser or mobile app with GPS, integrations, and reporting | Hybrid/remote teams, multi-site businesses, scaling companies | Subscription cost, training required |
Punch Clocks vs Digital: A Practical Comparison
Punch clocks eliminate time theft on-site but fail for remote workers. Digital systems solve hybrid work but require trust in self-reporting (or pair with GPS/geofencing). Many organisations combine both — a digital timesheet system with kiosk mode on-site and mobile access for field workers.
How Timesheets Support Legal Compliance
In the UK, the Working Time Regulations 1998 require employers to:
- Keep adequate records to demonstrate compliance with the 48-hour weekly average
- Maintain records for at least two years
- Ensure workers receive their entitled rest periods (11 consecutive hours per 24-hour period, 24 hours per 7-day period)
The European Court of Justice ruling in CCOO v Deutsche Bank SAE (2017) further reinforced that EU member states must establish an objective, reliable, and accessible system for measuring daily working hours. While the UK has diverged from the EU in some areas, the judgment has influenced best practice.
For US employers, the Fair Labor Standards Act (FLSA) requires accurate records of hours worked for non-exempt employees. Failure to maintain timesheets is one of the most common FLSA violations.
Best Practices for Timesheet Management
1. Set a Clear Submission Schedule
Employees should complete timesheets daily or at the end of each work week. The longer the gap between working and recording, the less accurate the data. Set a hard deadline — for example, timesheets due by Monday 10am for the previous week — and enforce it consistently.
2. Simplify the Timesheet Design
A good timesheet captures start time, end time, break duration, and total hours. Avoid asking for granular detail that adds administrative burden without improving accuracy. If you need project-level allocation, make that a separate field rather than the primary input.
3. Use Approval Workflows
Manager approval catches errors before they reach payroll. A single layer of review — a line manager confirming hours look reasonable — reduces disputes and overpayments. Digital systems automate this with routing rules.
4. Integrate with Payroll
The fewer manual data transfers between timesheet and payroll, the fewer errors. Modern systems push approved hours directly into payroll processing, eliminating double entry. This integration also speeds up pay cycle turnaround.
5. Track Overtime Automatically
Overtime rules vary by jurisdiction and contract. A good timesheet system applies your overtime thresholds automatically — whether that is daily (over 8 hours) or weekly (over 40 hours) — so managers do not have to calculate it manually.
6. Maintain an Audit Trail
Regulators and courts expect evidence. Your timesheet system should log who entered what, when it was entered, and who approved it. Paper timesheets with illegible handwriting do not survive scrutiny.
Digital Timesheet Features That Matter
When evaluating timesheet software, prioritise these capabilities:
- Mobile access — Essential for remote, field, and hybrid workers
- GPS and geofencing — Verifies location for off-site workers without micromanaging
- Automated reminders — Nudges employees to submit timesheets on time
- Overtime and compliance alerts — Flags when workers approach maximum hours
- Integration with payroll and project tools — Eliminates manual data entry
- Reporting and analytics — Shows labour cost distribution, overtime trends, and team utilisation
- Audit trail — Records every edit, approval, and override
Common Timesheet Errors and How to Prevent Them
| Error | Impact | Prevention |
|---|---|---|
| Rounding up hours | Overpayment, inflated labour costs | Use precise recording; round only at policy threshold |
| Missing breaks | Non-compliance with rest period laws | Make break logging mandatory |
| Late submission | Payroll delays, disputed figures | Automated reminders + enforcement |
| Buddy punching | Time fraud, inaccurate records | Biometric or mobile-based verification |
| No approval step | Errors reach payroll undetected | Require manager sign-off before processing |
Frequently Asked Questions
Are timesheets a legal requirement in the UK?
Timesheets themselves are not mandated by a single statute, but UK employers must keep adequate records to demonstrate compliance with the Working Time Regulations 1998 and National Minimum Wage calculations. In practice, a timesheet system is the standard way to satisfy this obligation. The ACAS guidance on record-keeping recommends maintaining clear, accurate records of hours worked.
How often should employees complete their timesheets?
Daily completion produces the most accurate data. If daily is impractical, weekly completion with a Monday deadline is the minimum standard. Monthly timesheets are unreliable — employees forget details within days, leading to inflated or deflated records.
Can I use a timesheet system to track remote workers?
Yes. Cloud-based timesheet tools with mobile apps let remote employees clock in and out from anywhere. Some systems add GPS verification or geofencing to confirm location. The key is choosing a tool that balances accountability with trust — excessive surveillance damages morale and may raise data protection concerns under UK GDPR.
What is the difference between a timesheet and a time clock?
A time clock is a device or mechanism that records the moment of clock-in and clock-out. A timesheet is the full record of hours worked over a period, including breaks, overtime, and approval status. A time clock feeds data into a timesheet, but a timesheet may also rely on self-reporting or project tracking tools.
Do salaried employees need to fill in timesheets?
If your salaried employees are exempt from overtime laws, you may not need detailed timesheets for payroll. However, timesheets still serve compliance, project costing, and workforce planning purposes. Many employers require all employees to log hours regardless of pay structure to maintain consistent records.
