What Is a Timesheet? A Complete Guide for 2026

A timesheet records the hours an employee worked in a given period - a day, week, or month. It captures start time, end time, break duration, and any overtime. That data feeds payroll, underpins legal compliance, and resolves disputes when time records are challenged.

The simplicity of the concept masks how much depends on getting it right.

Types of Timesheets

Paper timesheets are filled manually by the employee or supervisor. Common format: a printed grid with columns for date, start, end, break, and total. Low setup cost, high error rate. Retroactive filling - completing the sheet from memory at end of week rather than in real time - is the single biggest problem with paper records.

Digital timesheets are generated from check-in and check-out data. The system records the timestamp at clock-in and again at clock-out, calculates hours, deducts scheduled breaks, and produces a record that requires only supervisor approval. Error rates drop because data entry happens at the moment of the event, not from memory.

Project-based timesheets allocate hours to clients, projects, or cost centers. Used in professional services, consulting, construction, and any operation that tracks labour cost by job. Each entry requires a time code in addition to start and end times.

Legal Requirements

Most countries require employers to maintain working time records. The legal basis varies:

  • EU: The European Court of Justice ruling in CCOO v Deutsche Bank (2019) established that employers must have an objective, reliable system for recording daily working hours for all employees. This applies across all 27 EU member states.
  • US: The Fair Labor Standards Act (FLSA) requires employers to keep records of hours worked for all non-exempt employees. Retention: 2-3 years depending on record type.
  • UK: The Working Time Regulations 1998 require employers to keep records demonstrating compliance with the 48-hour average weekly limit and other protections. Retention: 2 years.
  • Australia: The Fair Work Act requires time and wages records for all national system employees. Retention: 7 years.

Standard retention across most jurisdictions runs 3-7 years. The safest practice: retain records for the longest period applicable to your operating countries.

Minimum Content Requirements

A compliant timesheet contains:

  • Employee name and identifier
  • Date of work
  • Start time (actual, not scheduled)
  • End time (actual, not scheduled)
  • Break duration
  • Total hours worked
  • Overtime hours and rate, if applicable
  • Employee confirmation or signature
  • Manager approval

Some jurisdictions require additional fields - job role, work location, project code. Check the specific requirements for your country and sector.

Common Errors and Their Consequences

Retroactive filling. The employee fills in a week's worth of hours on Friday afternoon from memory. Actual hours get rounded, forgotten, or misremembered. In a labour dispute, a record filled days after the fact carries less legal weight than a contemporaneous timestamp. In an audit, gaps or inconsistencies raise immediate questions.

Systematic rounding. Some payroll systems or supervisors round all hours to the nearest 15 minutes. Rounding down consistently - even by a few minutes per shift - constitutes underpayment. The US Department of Labor and UK HMRC have both pursued employers for systematic rounding that disadvantaged employees.

Missing approvals. A timesheet that lacks supervisor sign-off or employee confirmation is unilateral. If the employee later disputes the hours recorded, an unsigned record provides no protection.

Incorrect overtime calculation. Applying overtime thresholds to the wrong reference period - daily vs. weekly vs. reference period averages - produces payroll errors. In countries with dual thresholds (France at 35 hours, British Columbia at 8 hours daily/40 weekly), automated calculation prevents manual errors.

Digital Check-In Solves the Three Core Problems

Retroactive filling becomes impossible: the timestamp records the moment of clock-in, not when the employee remembers to fill in the form.

Rounding happens at system rules level, consistently and visibly, rather than through supervisor judgment.

Missing approvals get flagged: unapproved timesheets are held in a pending queue until the manager acts, creating an audit trail for every record in the system.

The result is a timesheet that is accurate at the source, compliant with retention requirements, and defensible in a dispute or inspection.

Rezano Timesheets

Rezano generates timesheets from QR, GPS, or manual check-in data. Records are timestamped at the moment of clock-in and clock-out. Break deductions are configured per shift type. Overtime calculates against the rules set for each employee's location and contract. Managers approve with a single tap. Records export to the payroll system and are stored for the retention period specified for each country of operation.

No retroactive filling. No manual rounding. No missing approvals sitting in an inbox.
