How Timesheet Approvals Improve Project Time Visibility

Recording project hours is only the first step in creating useful project time data.
Before those hours are used for reporting, managers often need to review them.
Are the hours recorded against the correct project?
Are the right tasks selected?
Does the timesheet appear complete?
Are there unusual entries that need clarification?
A timesheet approval process provides a defined step between employee time entry and project reporting.
Instead of treating every submitted timesheet as final, organizations can give managers an opportunity to review the information before it becomes part of their reporting process.
This article explains how timesheet approvals work, why they matter for project time visibility, and how organizations can create a more effective approval process.

What Is a Timesheet Approval Process?

A timesheet approval process is a workflow in which employees submit their completed timesheets to a manager or designated reviewer.
The reviewer examines the submitted information and either:
  • Approves the timesheet
  • Rejects the timesheet for correction
  • Requests clarification, depending on the organization’s process
A basic workflow looks like this:
Employee records time
→
Employee submits timesheet
→
Manager Review
→
Approve or reject
→
Approved data become available for reporting
This creates a clear distinction between time that has been entered and time that has been reviewed.
That distinction can be important when project reporting depends on reliable time information.

Why Does Timesheet Approval Matter?

Without a review process, organizations may collect time data without knowing whether the information has been checked.
For a small team with simple requirements, that may be acceptable.
But as the number of employees, projects, and reporting requirements increases, managers may need more visibility into the quality and status of submitted timesheets.
An approval workflow can help answer questions such as:
  • Which timesheets have been submitted?
  • Which timesheets are still waiting for review?
  • Which timesheets have been approved?
  • Which timesheets were rejected?
  • Which entries require clarification?
  • Which project hours have been reviewed?
This creates more visibility around the timesheet process itself.

How Timesheet Approvals Improve Project Time Visibility

1. They create a review point

The approval process gives managers a defined opportunity to review employee time.
For example, a manager may notice that an employee recorded significantly more time than expected on a particular task.
That doesn’t necessarily mean the entry is wrong. But it may be worth reviewing before the information is included in project reporting.

2. They help identify incorrect project or task entries

Project time is useful only when it is associated with the right project and task.
During review, managers can check whether employees selected the appropriate project and task.
This can help identify issues such as:
  • Time recorded against the wrong project
  • Incorrect task selection
  • Unexpected project activity
  • Duplicate or unusual entries
The approval process therefore provides an additional validation step.

3. They make timesheet status visible

A structured approval workflow makes it easier to understand where timesheets are in the process.
For example:
Not submitted → Submitted → Approved
or:
Submitted → Rejected → Resubmitted → Approved
This is much easier to manage than relying on email conversations or separate tracking spreadsheets.

4. They create accountability

When employees submit timesheets and managers review them, both sides have a defined responsibility.
Employees are responsible for recording their time.
Managers are responsible for reviewing submitted information.
This creates a clearer process than simply asking employees to maintain a spreadsheet and sending it to someone at the end of the reporting period.

5. They improve confidence in reporting data

Project reports are only as useful as the information behind them.
If hours are entered inconsistently or errors remain unnoticed, those problems can eventually appear in project reports.
An approval process does not guarantee that every entry is correct.
However, it introduces a review step before the data is treated as approved.

What Should Managers Check Before Approving a Timesheet?

Managers don’t necessarily need to inspect every hour in the same level of detail.
However, a consistent review process can help.
  • Check the project: Are the recorded hours associated with the correct project?
  • Check the task: Does the selected task match the work performed?
  • Check the total hours: Do the recorded hours appear reasonable for the period?
  • Check billable status: Where relevant, are billable and non-billable hours classified correctly?
  • Check unusual entries: Are there unusually high or low entries that require clarification?
  • Check comments: If additional context has been provided, does it explain the work recorded?
  • Check completeness: Has the employee submitted the expected timesheet?
The exact review process will depend on the organization’s policies and the nature of its projects.

What Happens When a Timesheet Is Rejected?

Rejection should not be treated as a failure of the timesheet process.
It is often simply part of the correction cycle.
For example:
Employee records time → Employee submits → Manager identifies an issue → Manager rejects with a comment → Employee corrects the entry → Employee resubmits → Manager approves
This creates a traceable process for correcting time information.
A rejection workflow is particularly useful when managers need employees to clarify project assignments, hours, or other timesheet information.

Timesheet Approval vs. Manual Email Approval

Organizations sometimes manage approvals through email.
An employee might send a spreadsheet to a manager.
The manager reviews it and replies:
Approved.
This can work for a small team.
But as the number of employees and projects grows, email-based approval becomes harder to manage.
Managers may need to:
  1. Find submitted spreadsheets.
  2. Check which employees have submitted.
  3. Identify which timesheets are still pending.
  4. Review each file.
  5. Respond to employees.
  6. Keep track of rejected submissions.
  7. Consolidate the approved information for reporting.
A structured timesheet workflow can bring these steps into one process.
The objective isn’t to eliminate email.
It is to avoid making email the primary system for managing timesheet status.

How Timesheet Approvals Support Project Reporting

One of the biggest benefits of an approval process is the connection between timesheet review and reporting.
Consider two situations.

Without approval

Employees enter hours. → Hours are collected. → Reports are created.
In this process, there may be little distinction between entered data and reviewed data.

With approval

Employees enter hours. → Employees submit timesheets.→ Managers review. → Timesheets are approved or rejected. → Approved information is used for reporting.
The second process introduces a quality-control step before reporting.
This can be particularly useful when project reports are used by managers or leadership to understand project effort.

How Approved Timesheets Improve Project Time Visibility

Once timesheets have been reviewed, organizations can use the resulting information to examine project effort from different perspectives.
For example:
  • By project: How many hours have been recorded against each project?
  • By employee: Which employees are contributing time to a project?
  • By task: Which project activities are consuming the most time?
  • By billable status: How much time is classified as billable or non-billable?
  • By approval status: Which timesheets are approved, pending, or rejected?
These views can help project managers understand not only how much time was recorded, but also the status and context of that time.

How Microsoft 365 Can Support Timesheet Approvals

Organizations already using Microsoft 365 may want their timesheet workflow to operate within the same environment.
SharePoint can provide a foundation for storing structured timesheet information, while Microsoft 365 can support the broader workflow.
A dedicated timesheet solution can bring together:
  • Employee time entry
  • Project and task selection
  • Timesheet submission
  • Manager approval
  • Rejection and resubmission
  • Reporting
  • Power BI analysis
The exact workflow should reflect the organization’s existing approval structure.

How Timesheet Pro 365 Handles Timesheet Approvals

Timesheet Pro 365 provides a structured workflow for employee timesheet submission and manager review within Microsoft 365 and SharePoint.
Employees record time against projects and tasks and submit their timesheets.
Managers can then review submitted timesheets and approve or reject them.
This creates a clear workflow:
Record → Submit → Review → Approve/Reject → Report
Timesheet Pro 365 also provides reporting capabilities around timesheet information, helping organizations understand submitted and approved project time.
For organizations using Power BI, timesheet information can also be used for additional analysis and dashboards.
The purpose is not to add an unnecessary approval layer.
It is to create a clear process for reviewing project time before it becomes part of broader reporting.

Common Timesheet Approval Problems

Managers approve everything without reviewing

If approval becomes a simple checkbox exercise, the workflow may not add much value.
Managers should know what they are expected to review.

Approval responsibilities aren’t clear

Employees should know who reviews their timesheets.
Managers should know which employees and projects they are responsible for.

Rejection reasons aren’t communicated

When a timesheet is rejected, employees need enough information to understand what needs to be corrected.

Managers don’t know what is pending

If pending timesheets are difficult to identify, managers may still need to rely on manual follow-up.
  • Approval happens too late

Approval happens too late

If timesheets are reviewed only long after the work occurred, correcting inaccurate entries becomes more difficult.
A defined approval schedule can help keep the process moving.

How to Build a Better Timesheet Approval Process

A good approval process doesn’t have to be complicated.
  • Define who approves each timesheet: Employees should know exactly who reviews their submissions.
  • Establish a regular submission schedule: For example, organizations may use weekly or monthly timesheet periods depending on their requirements.
  • Keep the review criteria simple: Managers should know what they are expected to check.
  • Make rejection actionable: If something is wrong, provide a clear reason for the employee.
  • Monitor pending approvals: Managers should have visibility into timesheets that are waiting for review.
  • Use approved data for reporting: Once a timesheet has passed the review process, the information can become part of project reporting.
The objective is a predictable process that employees and managers can follow consistently.

Timesheet Approval Shouldn’t Create More Administrative Work

An approval process is valuable only when it is easier to manage than the problem it is intended to solve.
If managers need to download spreadsheets, respond to emails, maintain separate approval trackers, and manually consolidate information, the process can become unnecessarily complicated.
A structured workflow should make the status of a timesheet clear:
What has been submitted?
What is waiting for approval?
What has been rejected?
What has been approved?
When this information is visible in one place, managers can spend less time figuring out the status of the process and more time reviewing the actual information.

From Approved Timesheets to Better Project Reporting

Timesheet approval is not the final goal.
The larger objective is to create reliable project time information that can support reporting.
The complete process looks like:
Capture
Employees record project and task hours.
→
Submit
Employees submit their timesheets.
→
Review
Managers check the information.
→
Approve
Approved time becomes part of the organization's reviewed data.
→
Report
Project teams analyze hours and project effort.
→
Analyze
Organizations can use reporting tool such as Power BI for deeper analysis.
This connection is important because project reporting starts with the quality of the underlying data.

Key Takeaways

Timesheet approvals are more than an administrative step.
They provide a structured review point between employee time entry and project reporting.
An effective approval process can help organizations:
  1. Review project and task assignments.
  2. Identify unusual or incorrect entries.
  3. Create visibility into timesheet status.
  4. Give managers a defined review responsibility.
  5. Improve confidence in project time data.
  6. Create a better foundation for reporting and analysis.
For project-driven organizations, the combination of time tracking + approval + reporting provides much more value than collecting hours alone.

Improve Visibility Into Project Time

Collecting employee hours is only the beginning.
A structured process that connects time entry, submission, approval, and reporting can give project teams greater visibility into where time is being spent and which information has been reviewed.
Timesheet Pro 365 provides project and task-based time tracking, timesheet submission and approval workflows, reporting, and Power BI integration within Microsoft 365 and SharePoint.
