Every Monday, somewhere in a small business, a manager is doing the same thing: chasing down timesheets. Sending Slack messages. Waiting for employees to "fill in the form". Then approving everything manually the day before payroll runs.
This process is broken — and it's costing you more than you think.
What Is a Timesheet Approval Workflow?
A timesheet approval workflow is the process by which an employee's recorded hours move from submitted to approved and then to payroll. At its simplest:
- Employee submits hours for a period (daily, weekly, or bi-weekly)
- Manager reviews and approves or rejects with a comment
- Approved timesheets flow to payroll
Without a defined workflow, hours get lost, disputes arise, and payroll delays become routine.
The Problem with Manual Timesheet Approval
Most small businesses manage timesheets through a combination of spreadsheets, email, and verbal confirmations. This creates:
- Lost approvals: An email approval has no audit trail. If a dispute arises, you can't prove who approved what.
- Late submissions: Without a system that prompts employees, timesheets come in whenever — sometimes not at all.
- Payroll errors: Hours get transcribed incorrectly from a spreadsheet into payroll software.
- Manager overload: If a manager is out for a day, the approval bottleneck backs up the entire payroll process.
- No visibility: Employees don't know if their timesheet was received, let alone approved.
According to workforce management research, businesses using manual approval processes spend an average of 4–6 hours per week on timesheet admin. That's $100–$200/week in direct labor cost for a manager earning $25–$33/hour.
The 5 Components of an Effective Approval Workflow
1. Submission Window
Define when employees must submit timesheets:
- Daily: Best for hourly staff or variable-hour workers. Catches errors while the day is fresh.
- Weekly: Most common for salaried teams. Employees submit by Monday for the previous week.
- Bi-weekly: Matches some payroll cycles, but errors can compound over two weeks before being caught.
2. Automatic Submission Reminders
Don't rely on employees to remember. A good system sends:
- A reminder notification on Friday afternoon (or end of pay period)
- An escalation reminder if the timesheet isn't submitted by the deadline
- A notification to the manager if a timesheet remains unsubmitted
3. Clear Approval Rules
Define who approves what before you set up your system:
| Scenario | Approver | |----------|----------| | Standard weekly hours | Direct manager | | Overtime hours (> 40 hrs/wk) | Manager + sign-off | | Hours logged to client projects | Project manager | | Manager's own timesheets | Their manager or owner |
The most common mistake is not defining who approves when the primary approver is unavailable. Set a backup approver for every role.
4. Approval Deadline
Managers need a deadline too — not just employees. Set an approval deadline 24–48 hours before payroll runs. This gives payroll processing time to resolve any discrepancies.
5. Payroll Export
Approved timesheets should flow directly to payroll — either through automatic integration or a clean export. The critical principle: approved timesheets should never need to be re-entered manually. Manual re-entry is where transcription errors happen.
Setting Up Your Workflow in WorkRoster
WorkRoster handles the complete approval lifecycle:
- Employees submit timesheets from any device — mobile, tablet, or desktop
- Managers receive an instant notification when timesheets are submitted
- Managers approve or reject with an optional comment (rejection comments are required)
- Employees see their approval status in real time
- Approved data exports to PDF or CSV for payroll
The entire flow takes under 5 minutes per week for most managers once employees are submitting consistently.
Common Workflow Mistakes (and How to Fix Them)
Mistake: Approving bulk batches at month-end This creates a massive admin burden and means errors aren't caught until they've compounded over 4 weeks. Fix: approve weekly, even if payroll runs monthly.
Mistake: Approving without reviewing Rubber-stamping timesheets defeats the purpose. Managers should verify: total hours are reasonable, overtime is accounted for, project codes are correct. Takes 2 minutes per timesheet, not 20.
Mistake: No rejection workflow If a manager rejects a timesheet but there's no clear process for the employee to correct and resubmit, the timesheet just sits in a "rejected" state and gets forgotten. Define the correction process upfront.
Mistake: Using approval as a control mechanism Some managers hold approvals until the last minute as a power move, or reject timesheets for minor formatting issues. This destroys trust. Define approval as administrative validation, not performance management.
Mistake: No delegate approver If the only approver is on leave, payroll grinds to a halt. Always configure a backup approver.
Measuring Whether Your Workflow Is Working
Track these metrics monthly:
- Submission rate: What % of timesheets are submitted by the deadline? Target: 95%+
- Approval cycle time: How many hours from submission to approval? Target: < 24 hours
- Late submissions: How many timesheets require chasing each period? Target: < 5%
- Rejection rate: What % of timesheets are rejected? Target: < 3% (high rejection = submission training issue)
If your submission rate is below 90%, the problem is usually the submission process (too complex) or the reminder system (not effective). If your approval cycle time is over 48 hours, the bottleneck is manager behavior, not employee behavior.
Frequently Asked Questions
What is a timesheet approval workflow? A timesheet approval workflow is the structured process by which employee-submitted hours are reviewed, approved, and passed to payroll. It defines who approves, when they approve, what happens when timesheets are rejected, and how approved data reaches payroll.
How long should timesheet approval take? For most businesses, timesheet review should take a manager 2–5 minutes per employee per week. Total approval time for a 10-person team should be under 30 minutes weekly. If it's taking longer, the submission process or data quality needs improvement.
Should timesheets be approved daily or weekly? Weekly approval is the most common and practical approach for most businesses. Daily approval makes sense for high-turnover hourly workplaces or operations where project costs are tracked in real time. Monthly approval is not recommended as errors can compound and are harder to trace.
Can timesheet approvals be automated? Yes — some businesses auto-approve timesheets that fall within a defined range (e.g., standard hours, no overtime, no anomalies). This works well for predictable, salaried roles. Overtime, unusual hours, or flagged entries should always require manual review.
What happens when a timesheet is rejected? A rejected timesheet should return to the employee with a specific comment explaining what needs to be corrected. The employee corrects and resubmits. The corrected version goes through the same approval flow. WorkRoster handles this automatically — rejection triggers an instant notification to the employee.
