What is a Timesheet? Definition, Types, Format & Purpose Explained

What is a Timesheet?

Every hour an employee works has a cost. But before that cost can be recorded, calculated, or paid, someone needs to track it.

That tracking tool is called a timesheet.

A timesheet is a document, physical or digital, that records the amount of time an employee or contractor spends working during a specific period. It captures hours worked per day, the type of work performed, and sometimes the project or client the work was done for.

Timesheets are the starting point for several critical business processes:

Calculating payroll (you cannot pay someone accurately without knowing their hours)
Billing clients (consultants and agencies bill by the hour)
Tracking project costs (knowing how many hours were spent on a task tells you its true cost)
Managing overtime (identifying when workers exceed standard hours)
Ensuring compliance with labour laws (many jurisdictions legally require working time records)

A timesheet sounds simple and at its core, it is. But it sits at the intersection of accounting, HR, project management, and legal compliance. Businesses that manage timesheets well control costs better, invoice clients more accurately, and run significantly smoother payroll operations.

Why Are Timesheets Important? The Purpose Behind the Paperwork

Timesheets are not bureaucratic busywork. Each one serves a specific business purpose and often several at once.

Accurate Payroll Processing

For hourly employees, timesheets directly determine pay. Without reliable time records, payroll is guesswork leading to overpayment, underpayment, and employee disputes.

Even for salaried employees, timesheets matter. They record overtime hours (which may trigger additional pay), track leave taken, and confirm attendance all of which affect the final payroll figure.

We covered the payroll register in an earlier article. The timesheet is the input that feeds the payroll register. Without accurate timesheets, the payroll register cannot be trusted.

Client Billing

Law firms, accounting firms, management consultants, architects, IT developers, and any other business that charges by the hour need timesheets to produce accurate invoices.

If a lawyer spends 4.5 hours reviewing a contract and 2 hours in a client meeting, the timesheet records those 6.5 hours against that client’s account. The billing system then multiplies by the hourly rate to generate the invoice. Without a timesheet, there is no audit trail for the client and no basis for the invoice.

In professional services firms, unbilled time is lost revenue. Timesheets are literally the mechanism that converts work into money.

Project Cost Tracking

In project-based businesses: construction, software development, consulting, engineering, each project has a budget for labour costs. Timesheets allocated to project codes allow the finance team to track how many hours (and therefore how much money) have been spent on each project against the budget.

This is the foundation of job costing and project accounting, essential tools for any business that works on multiple simultaneous projects with different cost structures.

Example: A software development company has three simultaneous client projects. Each developer fills in a timesheet allocating their hours to specific project codes each day. At the end of the week, the finance team can see that Project A has consumed 120 hours this week (within budget), Project B has consumed 85 hours (under budget), and Project C has consumed 210 hours (40 hours over budget, a flag that needs management attention).

Without timesheets, this visibility is impossible.

Overtime Monitoring and Compliance

Labour laws in most countries specify standard working hours and require higher pay rates for overtime. Timesheets are the mechanism for identifying when overtime thresholds are crossed.

In the United States, the Fair Labor Standards Act (FLSA) requires that non-exempt employees be paid at least 1.5 times their regular rate for hours worked beyond 40 in a workweek. Timesheets are the legal basis for calculating this.

In the United Kingdom, the Working Time Regulations 1998 limit average working hours to 48 per week (unless opted out) and require employers to keep records adequate to verify compliance.

In Bangladesh, the Bangladesh Labour Act 2006 specifies that no worker shall work more than 8 hours per day or 48 hours per week as regular hours, with overtime not exceeding 2 hours per day and paid at twice the basic rate (Section 100-108). Timesheets are what make this enforceable in practice.

In Malaysia, the Employment Act 1955 governs working hours and overtime. Employees earning below the wage threshold are entitled to overtime pay calculated on recorded hours.

Productivity and Resource Management

Timesheets give managers visibility into how teams spend their time. Over weeks and months, timesheet data reveals patterns which tasks are consuming more time than expected, which projects are running efficiently, and where capacity gaps exist.

This data drives better resource allocation, project planning, and staffing decisions.

What is a Timesheet? Definition, Types, Format & Purpose Explained

Types of Timesheets

Timesheets come in several forms, varying by time period covered, level of detail, and purpose.

Daily Timesheet

Records hours for a single day usually broken down by hour or half-hour, sometimes by specific tasks or projects within the day.

Best for: Field workers, factory workers with shift-based rotas, employees working across multiple projects in a single day.

Format: Rows for each hour of the workday (8 AM to 6 PM, for example), columns for work start, work end, break time, total hours, and activity description.

Example:

Time	Activity	Project/Client	Hours
08:00 – 10:00	Financial statement review	Client A	2.0
10:00 – 10:15	Break	—	—
10:15 – 12:30	Tax return preparation	Client B	2.25
12:30 – 13:15	Lunch	—	—
13:15 – 16:00	Audit fieldwork	Client C	2.75
16:00 – 17:30	Report writing	Client A	1.5
Total			8.5 hrs

Weekly Timesheet

The most common format. Records hours worked each day across a seven-day week, with a total at the end.

Best for: Office employees, part-time workers, any employee paid on a weekly or bi-weekly basis.

Format: Rows for each day of the week, columns for start time, end time, break, regular hours, overtime hours, and notes.

Example: Weekly Timesheet — Rashida Begum, Finance Executive

Day	Date	Start	End	Break	Regular Hrs	Overtime Hrs
Monday	02 Jun	09:00	18:00	1 hr	8.0	0
Tuesday	03 Jun	09:00	19:30	1 hr	8.0	1.5
Wednesday	04 Jun	09:00	18:00	1 hr	8.0	0
Thursday	05 Jun	09:00	20:00	1 hr	8.0	2.0
Friday	06 Jun	09:00	18:00	1 hr	8.0	0
Saturday	07 Jun	—	—	—	0	0
Sunday	08 Jun	—	—	—	0	0
Total					40.0	3.5

Bi-Weekly Timesheet

Covers two weeks in one document. Used by organisations that process payroll every two weeks — common in the US, Canada, and Australia.

Same structure as the weekly timesheet but doubled 14 rows (one per day), showing regular and overtime hours for each, with two-week totals.

Monthly Timesheet

Covers an entire calendar month. Common in countries where monthly payroll is standard including Bangladesh, India, the UK, and much of Europe.

For salaried employees on a fixed monthly pay, the monthly timesheet primarily tracks attendance (present / absent / leave type) rather than exact clock-in/clock-out times. For hourly workers or those earning overtime, it also records daily hours.

Example: Monthly Attendance & Hours Record

Date	Day	Status	Hours Worked	Overtime	Notes
01 Jun	Sun	Weekly Off	—	—
02 Jun	Mon	Present	8.0	0
03 Jun	Tue	Present	9.5	1.5	Month-end close
04 Jun	Wed	Present	8.0	0
…	…	…	…	…
28 Jun	Sat	Present	5.0	0	Half day
29 Jun	Sun	Weekly Off	—	—
30 Jun	Mon	Present	8.0	0
Total			188.0	12.5

Project-Based Timesheet

Allocates hours to specific projects, clients, or tasks rather than simply recording total hours worked. Essential for professional services firms, consulting, construction, and software development.

Each row represents a project or task. Each column represents a day of the week. The employee enters the hours spent on each project each day.

Example: Project Timesheet — Week of 2–8 June

Project / Task	Mon	Tue	Wed	Thu	Fri	Total
Project Alpha — design	3.0	0	2.0	0	1.0	6.0
Project Beta — testing	2.0	4.0	3.0	2.5	3.0	14.5
Project Gamma — meetings	1.0	1.5	0	2.0	1.0	5.5
Internal — admin	2.0	0.5	1.0	1.5	1.0	6.0
Leave	0	0	0	0	0	0
Total Hours	8.0	6.0	6.0	6.0	6.0	32.0

At the end of the week, the finance team can see exactly how many hours were charged to each project enabling accurate project cost tracking and client billing.

What Does a Timesheet Contain? The Key Components

Regardless of the format, a complete timesheet should contain these elements:

Employee identification:

Employee name and ID number
Department and job title
Supervisor / manager name

Period covered:

Start date and end date of the timesheet period
Pay period reference (useful for linking to payroll)

Daily time records:

Date for each row
Day of the week
Clock-in time (start of work)
Clock-out time (end of work)
Break duration (lunch break, rest breaks)
Total hours worked per day (net of breaks)
Regular hours vs overtime hours (if applicable)
Attendance status: Present / Absent / Annual Leave / Sick Leave / Public Holiday

Project or task codes (for project-based timesheets):

Project code or client name
Task description
Hours allocated per project per day

Summary totals:

Total regular hours for the period
Total overtime hours for the period
Total leave days taken
Grand total hours

Approval signatures:

Employee signature (certifying the record is accurate)
Supervisor approval signature and date

Notes or remarks:

Any explanation for overtime, late starts, early finishes, or absence

Timesheets and Payroll: The Direct Connection

The timesheet is the foundational input document for payroll processing. Here is how the connection works:

For hourly workers:

Gross Pay = (Regular Hours × Regular Rate) + (Overtime Hours × Overtime Rate)

Both figures come directly from the timesheet. Without accurate time records, gross pay cannot be calculated.

Example: A factory worker’s timesheet for the week shows 40 regular hours and 8 overtime hours. Regular rate = $12/hour. Overtime rate = $18/hour (1.5×).

Gross Pay = (40 × $12) + (8 × $18) = $480 + $144 = $624

Every figure in that calculation was driven by the timesheet.

For salaried workers:

While base salary is fixed, timesheets still matter for:

Verifying full attendance (detecting unauthorised absences that affect net pay)
Calculating overtime if applicable
Processing leave entitlements correctly
Supporting any performance or productivity bonuses tied to hours worked

The payroll process flow:

Timesheets → Payroll Register → Journal Entry → Bank Payment to Employees

Each stage feeds the next. A timesheet error in week one ripples through every subsequent step.

Timesheets and Job Costing: The Accounting Value

In job costing (also called project costing), labour cost is one of three main inputs into the cost of a job:

Direct materials — the physical inputs used
Direct labour — the people-hours spent on the job
Overhead — allocated indirect costs

Timesheets provide the data for the direct labour component.

The formula:

Direct Labour Cost per Job = Hours Worked on Job × Labour Rate per Hour

Example: A construction company is building three projects simultaneously. Its site engineer earns $35 per hour. His timesheet for the week shows:

Project A: 18 hours
Project B: 12 hours
Project C: 10 hours

Direct Labour Cost allocated:

Project A: 18 × $35 = $630
Project B: 12 × $35 = $420
Project C: 10 × $35 = $350
Total: $1,400 (consistent with his gross weekly pay)

Without the timesheet, the company cannot allocate labour costs to specific jobs and therefore cannot know whether any given job is profitable.

The journal entry for labour costs:

Dr. Work in Progress — Project A     630
Dr. Work in Progress — Project B     420
Dr. Work in Progress — Project C     350
    Cr. Wages Payable / Accrued Wages     1,400

Each project’s WIP account accumulates its share of labour cost. When a project is complete, the total cost (materials + labour + overhead) is transferred to Cost of Goods Sold or Cost of Sales.

This entire mechanism depends on accurate timesheets.

Paper Timesheets vs Digital Timesheets

Timesheets have evolved significantly from handwritten ledger books to sophisticated cloud-based systems. Both approaches remain in use today depending on the size and nature of the business.

Paper / Manual Timesheets

Still common in small businesses, agricultural work, and contexts where workers have limited technology access.

Advantages:

Simple to understand, no training required
Works without electricity or internet
Low cost — just paper and a pen
No system downtime risk

Disadvantages:

Prone to human error in recording and transcription
Easy to falsify or alter (time fraud risk)
Manual data entry into payroll systems — slow and error-prone
Difficult to aggregate for analysis
Storage and retrieval for audits is cumbersome

Spreadsheet-Based Timesheets

Excel or Google Sheets timesheets represent the middle ground structured and easier to aggregate than paper, but still manual in terms of data entry.

A well-designed Excel timesheet template can auto-calculate daily totals, weekly totals, overtime, and gross pay using formulas. This reduces calculation errors while remaining accessible to any business.

For small and medium businesses without a dedicated HR system, a standardised Excel timesheet template is a practical and cost-effective solution.

Digital Timesheet Software

Dedicated timesheet applications and modules within HR/payroll systems offer significant advantages for businesses with more than a handful of employees.

How digital timesheets work:

Employees log in to the system (via web, desktop app, or mobile) and clock in/out or manually enter hours. The system records timestamps, calculates totals, flags anomalies, and routes the timesheet through an approval workflow. Approved timesheets feed directly into payroll processing eliminating the manual re-entry step.

Popular timesheet and time-tracking tools globally:

Toggl Track — simple time tracking, popular with freelancers and agencies
Clockify — free timesheet and time tracking tool widely used by SMEs
Harvest — combines time tracking with invoicing, popular with professional services firms
TSheets (now QuickBooks Time) — integrates directly with QuickBooks payroll
BambooHR / Gusto / ADP — full HR platforms with integrated time and attendance
SAP Time Management — enterprise-level time recording within SAP HCM
Jira / Tempo Timesheets — project-based time tracking for software development teams

Biometric and hardware-based systems:

Many factories and large offices use fingerprint scanners, card swipe readers, or facial recognition systems to record clock-in and clock-out times automatically. This eliminates buddy-punching (where one employee clocks in for another) a significant time fraud risk in manual systems.

These hardware systems generate attendance records automatically, which feed into payroll software.

Timesheets and Labour Law: International Compliance Requirements

Maintaining accurate time records is not just good practice in many jurisdictions it is a legal obligation.

United States — Fair Labor Standards Act (FLSA):

The FLSA requires employers to keep records of hours worked for all non-exempt (hourly) employees. While the law does not specify a particular form, it does require that records show daily and weekly hours worked for each employee. Failure to maintain these records can result in significant back-pay liabilities and penalties in wage-and-hour lawsuits.

United Kingdom — Working Time Regulations 1998:

Employers must keep adequate records to show compliance with the 48-hour average working week limit. Records must be retained for two years.

European Union — ECJ Ruling 2019:

In a landmark European Court of Justice ruling (CCOO v Deutsche Bank, 2019), the ECJ held that EU member states must require employers to set up an objective, reliable, and accessible system for recording the daily working time of each worker. This ruling pushed many European countries toward stricter time-recording requirements.

Australia — Fair Work Act 2009:

Employers must keep time-and-wages records for each employee for seven years. Records must include the number of hours worked each day and the total number of hours each week.

Bangladesh — Bangladesh Labour Act 2006:

Section 100 limits working hours to 8 per day and 48 per week for factory workers. Employers are required to maintain records of attendance and hours worked. Overtime must be recorded separately and must be compensated at twice the basic wage rate. Labour inspectors can request these records during inspections.

Malaysia — Employment Act 1955:

Employers must maintain wage registers and records of working hours for employees. These records must be kept for six years and be available for inspection by labour inspectors. The Employment Act governs overtime pay for employees earning below the statutory wage threshold.

The specific requirements vary, but the common thread across all jurisdictions is this: if you employ people, you must be able to prove the hours they worked. Timesheets — whether paper or digital — are how you do that.

Timesheet Fraud: What It Is and How to Prevent It

Timesheet fraud is the deliberate falsification of time records to claim pay or client billing for hours not actually worked. It is more common than many managers realise and represents a significant financial risk.

Common forms of timesheet fraud:

Buddy punching — one employee clocks in on behalf of another who has not yet arrived. Prevented by biometric systems (fingerprint or facial recognition).

Inflated hours — claiming more hours than actually worked. Prevented by supervisory review, random audits, and cross-checking against access logs or computer login data.

Project misallocation — charging non-billable internal time to client project codes to hit billable hour targets. Prevented by project manager review and regular comparison of billed hours to client deliverables.

Ghost employees — timesheets and payroll for fictional employees. Prevented by the ghost employee audit procedures we discussed in the payroll register article, physically verifying employee existence and matching bank payment details.

Prevention measures:

Require employee self-certification and supervisor sign-off on every timesheet
Use biometric or digital clock-in systems with audit trails
Conduct random spot-checks — comparing timesheets to building access logs, computer activity records, or client deliverables
Implement segregation of duties — the person who approves timesheets should not be the person who processes payroll from them
Establish a clear policy on consequences for timesheet fraud
Use project-level review — project managers comparing hours billed to work completed

Timesheet Best Practices

Whether you are implementing timesheets for the first time or improving an existing process, these practices make a significant difference:

Fill in daily, not retrospectively. The longer the gap between working and recording, the less accurate the record. Daily completion takes two minutes; reconstructing a week from memory on Friday afternoon takes twenty — and is much less reliable.

Be specific about task descriptions. “Client work” is useless. “Audit fieldwork — vouching of sales invoices for Q2 — Client ABC” is useful. Specific descriptions support client billing, project cost analysis, and future project planning.

Record all time honestly, including non-billable time. Many professionals are tempted to hide non-productive time. Accurate records — including time spent on admin, training, and internal meetings — give management a realistic picture of capacity utilisation.

Standardise project codes. If timesheets use inconsistent project names (“Proj A”, “Project-A”, “Alpha Project”), data aggregation becomes a nightmare. Standardise codes across the organisation.

Process approvals promptly. Timesheet approvals should not sit in a manager’s inbox for a week. Delayed approvals delay payroll and create operational stress.

Retain records for the legally required period. The minimum retention period varies by country — commonly 5 to 7 years. Build a document retention policy around this.

Summary

A timesheet is a document that records the time an employee spends working, typically broken down by day, project, or task for a defined period.
Timesheets serve multiple purposes: payroll calculation, client billing, project cost tracking, overtime management, and legal compliance.
The main types are: daily, weekly, bi-weekly, monthly, and project-based timesheets.
Timesheets are the primary input for the payroll register and for job costing — two of the most important accounting functions in any labour-intensive business.
Labour laws in the US (FLSA), UK (Working Time Regulations), EU, Australia (Fair Work Act), Bangladesh (Labour Act 2006), and Malaysia (Employment Act 1955) all require employers to maintain time records.
Digital systems offer significant advantages over paper — accuracy, speed, audit trail, and direct payroll integration — but paper and spreadsheet-based systems remain practical for small businesses.
Timesheet fraud is a real risk. Prevention requires supervisory approval, segregation of duties, biometric systems, and periodic audits.
Best practice: complete timesheets daily, use specific task descriptions, standardise project codes, and approve promptly.

Frequently Asked Questions (FAQs)

Q: Are employers legally required to use timesheets?

Employers are not always required to use a specific format called a "timesheet," but most labour laws require them to maintain accurate working time records. Timesheets are the standard practical tool for meeting that obligation. The specific requirements vary by country and employment type hourly workers typically require more detailed records than salaried employees.

Q: Do salaried employees need to fill in timesheets?

It depends on the organisation. Some companies require all employees to complete timesheets for project tracking and resource management purposes, even if pay is not directly linked to hours. Others only require timesheets from hourly or overtime-eligible employees. In professional services firms, all fee-earners regardless of salary structure typically complete project timesheets for billing purposes.

Q: How do timesheets relate to overtime pay?

Timesheets record the total hours worked each day and week. When hours exceed the legally defined or contractually agreed standard (e.g., 48 hours per week in Bangladesh, 40 hours in the US), the excess is overtime. The overtime hours from the timesheet feed into the payroll register, where they are multiplied by the applicable overtime rate (typically 1.5× or 2× the regular rate) to calculate overtime pay.

Q: What is the difference between a timesheet and a time card?

A time card (or punch card) was historically a physical card inserted into a time clock machine that stamped the arrival and departure times mechanically. It was common in factories. A timesheet is a broader record, it can include time-card data plus additional detail like project codes, task descriptions, and leave records. In modern usage, the terms are sometimes used interchangeably to mean any working-time record.

Q: How long should timesheets be kept?

Retention requirements vary by country. As a general guide: Bangladesh (5 years under accounting standards, longer under labour law inspection requirements), UK (2 years under Working Time Regulations, 6 years recommended for payroll records), US (2 years under FLSA, 7 years recommended for tax purposes), Australia (7 years under Fair Work Act). When in doubt, apply the longest applicable retention period in your jurisdiction.

Q: Can employees access their own timesheet records?

In most jurisdictions, employees have the right to access their own employment records, including time records. This is explicit in UK GDPR and similar data protection frameworks. Employers should have a clear process for employees to request and review their own timesheet records.
