Timesheet
A record documenting the hours an employee has worked during a specific pay period, used to calculate wages, track project costs, and maintain compliance with labor regulations.
What Is a Timesheet?
Key Takeaways
- ✓A timesheet is a structured record of hours worked by an employee, typically organized by day and pay period. It serves as the source document for payroll calculations and labor cost reporting.
- ✓80% of paper-based timesheets contain at least one error that needs correction before payroll can process them (American Payroll Association, 2024).
- ✓Timesheet errors affect 5 to 6% of total payroll in organizations relying on manual processes, translating directly into overpayments, underpayments, or both (Deloitte, 2023).
- ✓Digital timesheets reduce processing errors by 90% or more compared to paper, and they cut the time HR staff spend on timesheet management from hours to minutes per pay cycle.
- ✓Under the FLSA, employers must maintain accurate time records for non-exempt employees. Timesheets are the primary evidence in wage and hour disputes.
A timesheet is the document that translates work into pay. It records when an employee worked, how long they worked, and often what they worked on. Despite sounding mundane, timesheets sit at the center of one of the most consequential processes in any organization: making sure people get paid correctly. The concept hasn't changed since the mechanical time clock was invented in 1888. What's changed is the medium. Paper timecards gave way to spreadsheets, which gave way to web-based systems, which are now giving way to mobile apps with GPS verification. Each evolution reduced errors and increased the speed of data flow from time worked to paycheck issued. For professional services firms (consulting, legal, accounting, agencies), timesheets serve a second purpose beyond payroll: project costing and client billing. Every hour tracked against a project code feeds into profitability analysis and client invoices. In these organizations, timesheet accuracy directly affects revenue recognition and client relationships.
Types of Timesheets
Timesheets come in various formats depending on the industry, workforce type, and what data needs to be captured.
| Type | Format | Data Captured | Common Use Cases |
|---|---|---|---|
| Daily timesheet | Hours recorded each day separately | Clock-in/out times, breaks, total daily hours | Hourly workers, construction, hospitality |
| Weekly timesheet | One row per day for a 7-day period | Daily hours, weekly totals, overtime | Most common format for payroll processing |
| Bi-weekly/semi-monthly | Two-week or half-month period | Daily hours, period totals, overtime | Organizations with bi-weekly or semi-monthly pay cycles |
| Project-based timesheet | Hours allocated by project or task | Hours per project, billable vs. non-billable | Consulting, agencies, IT services, law firms |
| Exception-based timesheet | Only deviations from standard schedule recorded | Absences, overtime, schedule changes | Salaried workers with fixed schedules |
What a Timesheet Should Include
A compliant, useful timesheet captures more than just clock-in and clock-out times.
Required elements for FLSA compliance
Employee name and identifying information, day and time when the workweek begins, hours worked each day, total hours worked each workweek, and basis on which wages are paid (hourly rate, weekly salary, etc.). While the FLSA doesn't mandate a specific format, these data elements must be retrievable from whatever system you use. If audited, you need to produce this information going back at least 3 years.
Additional elements for operational value
Project or cost center codes (for labor cost allocation), job or task codes (for productivity analysis), break start and end times (for meal/rest break compliance), location (for multi-site operations), pay rate indicators (regular, overtime, differential), and manager approval signature or digital confirmation. The more context a timesheet captures, the more useful it becomes for workforce analytics beyond simple payroll.
Common Timesheet Errors and How to Prevent Them
Timesheet errors cost real money. Understanding the most frequent mistakes helps you design processes and systems that catch them early.
Late submission
The most common issue. When employees submit timesheets late, payroll processing is delayed or forced to estimate hours. Set clear deadlines with automated reminders (24 hours before, 4 hours before, at deadline). Some organizations dock a small amount of PTO for repeated late submissions, though this can create legal issues if not handled carefully. The simplest fix is to make timesheet submission easy: mobile access, one-tap approval, and pre-populated schedules reduce friction.
Incorrect coding
Employees assign hours to the wrong project, department, or pay code. This corrupts labor cost data and can affect client billing. Limit the available codes to only those relevant to each employee's role. Use default codes for standard work and require active selection only for exceptions. Review coding accuracy monthly, especially for project-based timesheets where billing depends on correct allocation.
Rounding and estimation
Employees who fill out timesheets retrospectively tend to round to the nearest hour or estimate hours from memory. Studies show that retrospective time entry is 30 to 40% less accurate than real-time tracking. The solution is to make real-time entry the default: clock-in at start, clock-out at end, with the system calculating hours automatically.
Buddy punching and falsification
One employee clocks in or submits time for another who isn't present. Biometric systems eliminate this for clock-based timesheets. For manual submission systems, manager attestation and random audits provide deterrence. Clear policies about falsification consequences, which can include termination, should be communicated during onboarding.
Moving from Paper to Digital Timesheets
If you're still using paper timesheets or basic spreadsheets, the transition to a digital system is one of the highest-ROI moves in HR operations.
Benefits of digital timesheets
Automated calculations eliminate math errors. Real-time visibility lets managers catch issues during the pay period instead of after. Automated reminders reduce late submissions. Integration with payroll eliminates re-keying. Audit trails provide compliance documentation. Mobile access lets employees submit time from anywhere. Reporting capabilities turn raw hours into actionable labor cost insights.
Common resistance and how to address it
Employees who've used paper for decades will resist change. Address this head-on: show them how the new system protects their pay by eliminating errors that short-change them. Provide hands-on training, not just a PDF guide. Assign digital champions in each department to help colleagues. Run paper and digital in parallel for 2 to 3 pay cycles so people build confidence before the paper option disappears. For field workers without desk access, ensure the mobile experience is genuinely simple, not a scaled-down version of the desktop app.
Timesheets for Project-Based Work
In professional services, timesheets serve a fundamentally different purpose than in shift-based operations. They're not just about payroll. They're about revenue.
Billable vs. non-billable tracking
Professional services firms track every hour as either billable (chargeable to a client) or non-billable (internal meetings, admin, training, business development). The billable utilization rate, billable hours divided by total available hours, is the single most important profitability metric. Target utilization varies by role: 60 to 70% for senior consultants, 75 to 85% for mid-level, and 80 to 90% for junior staff. Timesheet compliance rates directly affect the accuracy of utilization reporting and client invoicing.
Revenue recognition implications
For firms billing on a time-and-materials basis, unrecorded hours are lost revenue. If a consultant works 45 hours on a client project but only logs 40, the firm can't bill those 5 hours. At a billing rate of $200/hour, that's $1,000 in lost revenue per week from a single timesheet shortfall. Across a 500-person firm, even a 3% underreporting rate can mean millions in unbilled revenue annually.
