An attendance record can tell a business that an employee worked eight hours. It does not necessarily show whether those hours were spent delivering Project A, supporting Project B, attending an internal meeting or completing administrative work.
A project timesheet adds that missing layer. It records where working time was spent so project managers and finance teams can connect employee effort with individual projects and activities. When the data is structured and reviewed consistently, it can support labour costing, client billing, resource planning and comparisons between planned and actual project effort.
A project timesheet is a record of the time a person spends on specific projects, tasks or project activities during a defined reporting period.
At its simplest, it connects:
Employee → Project → Task or activity → Date → Hours
Depending on the business, a project timesheet may also record whether the time is billable, a short description of the work, approval status, or information required for labour costing.
The purpose is different from simply knowing how many hours an employee worked. A project manager also needs to understand where those hours went and whether the effort being consumed by a task aligns with what was originally planned.
The Project Management Institute's guidance on project time collection describes this activity-centred approach to recording labour. Instead of assigning labour costs only to organisational units, hours can be associated with project activities so that labour effort and cost can be connected with the work that consumed them.
Project timesheets and attendance records both deal with employee time, but they answer different questions.
Consider an employee who works eight hours in a day. An attendance system may show that the employee was present for those eight hours. A project timesheet could show that four hours were spent on Project A, two on Project B, one on an internal meeting and one on administration.
Both records can be useful, but they serve different operational purposes. HAL similarly separates Time & Attendance from its dedicated Timesheet functionality.
The right level of detail depends on what the organisation plans to do with the data. A consultancy using time-and-material billing may need more information than an internal project team that only wants to compare estimated and actual effort.
Common fields include:
More detail is not always better. If employees need to choose between hundreds of similar activity codes or write lengthy descriptions for routine work, timesheet completion can become unnecessarily cumbersome.
The aim is to collect enough information to support the decisions and downstream processes that actually use the timesheet.
A simple project timesheet could look like this:
The employee worked eight hours, but the record provides considerably more information than attendance alone. It shows which projects consumed the day, which activities were performed and which hours may qualify as billable under the relevant customer agreement.
In this example, 5.5 hours are marked billable. That does not mean 5.5 out of eight hours is automatically the correct utilisation target. Billable-time expectations vary by role, company and commercial model.
A timesheet becomes useful only when the organisation defines how time should be entered, reviewed and used. The following process keeps the data focused on project management rather than treating time entry as an administrative exercise.
Employees need clear options when they record their work. Project names or codes should identify the correct engagement, while task or activity codes provide enough detail to show what part of the project consumed the time.
Avoid creating so many overlapping categories that employees have to guess between nearly identical codes. If different people consistently classify the same activity differently, the resulting data becomes difficult to compare.
Internal categories should also exist where necessary for non-project activities such as administration, training or internal meetings. Otherwise, employees may end up allocating non-project hours to whichever project code is easiest to select.
Teams need a shared understanding of what should be allocated to a project.
Depending on the business, project time might include direct delivery work, project meetings, client discussions, travel, testing, rework or project-management activities. Other activities may be recorded separately as internal administration, training, pre-sales or non-project work.
The important point is consistency. If one employee records project meetings against the project while another classifies the same type of meeting as general administration, project effort will be understated in one case and overstated in another.
Timesheet data is more reliable when employees record hours close enough to the work that they can reasonably remember how their time was allocated.
A business might use daily entry with weekly submission, weekly reporting, or another cycle that aligns with project reporting, billing and payroll requirements. There is no universal reporting frequency that works for every organisation.
PMI's project time collection guidance also notes the importance of defining a consistent reporting cycle. Where timesheet data feeds project performance analysis, the reporting period should align appropriately with the period used to review project status.
For businesses that charge customers based on time, a timesheet may need to distinguish between billable and non-billable work.
Billable time can include work that the customer agreement allows the business to charge. Non-billable project time may include internal reviews, rework, administration or other activities that support delivery but cannot be invoiced separately.
The distinction is also useful when analysing project profitability. A project can consume substantially more labour than the hours eventually billed to the customer.
However, billable and productive should not be treated as synonyms. Necessary quality checks, internal coordination and project management may create value even when they are not directly billable.
A straightforward workflow can be:
Employee enters time → submits timesheet → manager or project owner reviews → correction where needed → approval
Approval should have a purpose. The reviewer may check that hours are allocated to the correct project, activity codes are reasonable, the billable classification is appropriate and unusual entries have enough explanation.
Approvals should not become a line-by-line bureaucracy where managers approve entries without examining them. The amount of scrutiny should reflect the financial and operational importance of the data.
If approved entries later need correction, the business should also have a controlled way to make the change rather than silently replacing the original information.
Approved project hours can support several downstream processes.
For labour costing, a simple calculation is:
Project labour cost = Project hours × Applicable labour-cost rate
For time-based customer billing:
Billable value = Approved billable hours × Agreed billing rate
The cost rate and billing rate should not be confused. The internal cost of an employee's hour and the rate charged to the customer can be different figures serving different purposes.
Timesheet data can also support invoices where the commercial agreement is based on time and materials. HAL's Invoicing functionality supports invoicing workflows that include time-and-material documents, while HAL Timesheets documents invoice generation based on timesheet entries and expenses.
One of the most useful applications of project timesheets is comparing planned effort with what the work actually consumed.
Suppose a task was estimated at 80 hours but approved timesheets show 110 hours. The 30-hour difference should prompt investigation rather than an immediate conclusion about employee performance.
Questions might include:
HAL Project Management documents project scheduling, task allocation and comparison of planning information with actual timesheet data. Historical timesheet information can also provide useful inputs when estimating similar work in the future.
For more on different ways to build project estimates, see HAL's guide to project estimation techniques.
Timesheet data can contribute to several project-management decisions when it is recorded consistently.
The Association for Project Management's guidance on project controls describes project controls as covering areas such as time, cost, resources, risk, change and performance reporting. It also emphasises measuring completed work and forecasting what may happen next once a project is underway.
A timesheet can provide part of the evidence needed for that process. It is an input into project control rather than a complete project-control system by itself.
Labour can represent a significant share of project cost, particularly in consulting, professional services, implementation and other people-intensive work.
If accounting records payroll only at company or department level, managers may know how much the organisation spent on labour without knowing clearly which projects consumed that cost. Project timesheets help create that link.
For example, assume an engineer records 20 approved hours against Project A and the organisation applies a project labour-cost rate of SAR 120 per hour:
20 hours × SAR 120 = SAR 2,400
That SAR 2,400 can then form part of the project's labour-cost view.
The appropriate labour-cost rate depends on the organisation's accounting approach. Some businesses may use direct wage cost, while others may apply a broader rate that incorporates selected employment or overhead costs. A timesheet records the effort; the business still needs to determine the appropriate costing methodology.
Timesheets are particularly important for businesses working under time-and-material arrangements because customer charges can depend directly on approved hours.
A typical workflow is:
Approved timesheet → Billable hours → Contracted billing rate → Invoice
Not every project uses this model. Fixed-price, milestone-based and retainer arrangements may use different billing structures. Even then, project timesheets can still help management understand how much internal labour the project consumed compared with the revenue earned.
HAL Timesheets documents billable-time tracking and invoicing based on timesheet entries and expenses. The key control is that recorded hours should not automatically become customer charges unless they are valid under the contract and appropriately reviewed.
Poor timesheet practices can produce data that looks precise while providing little useful project insight.
Common mistakes include recording most work against one generic project code, reconstructing an entire week long after the work happened, creating too many confusing task categories, and failing to distinguish billable from non-billable work where that distinction matters.
Problems also arise when timesheets are approved without meaningful review or when previously approved entries can be changed without a controlled correction process.
Another mistake is treating project hours as a direct measure of productivity. A person recording more hours has not necessarily produced more value, just as a task exceeding its estimate does not automatically indicate poor performance. Scope, complexity, quality, rework and the quality of the original estimate all affect the interpretation.
✓ Project codes are clear and current
✓ Task and activity categories are easy to understand
✓ The reporting period is defined
✓ Employees know which work should be recorded against projects
✓ Billable rules are documented where relevant
✓ Time is recorded consistently
✓ Submitted hours receive appropriate review
✓ Corrections follow a controlled process
✓ Approved time feeds the correct downstream process
✓ Planned and actual effort are compared
✓ Completed or inactive project codes are closed
✓ Timesheet detail is useful without becoming excessive
A good timesheet process should make project information easier to use. If employees spend more time interpreting the form than recording their work, the structure probably needs simplifying.
A spreadsheet can work well for a small team with only a few projects and straightforward reporting requirements. Dedicated software becomes more useful as projects, users and downstream workflows increase.
The decision should therefore be based on complexity rather than assuming every business needs specialised software immediately.
HAL Timesheets connects time information with project and commercial workflows. Its current product documentation includes expected and actual project hours, re-forecast comparisons, billable-time tracking, resource allocation, project profitability analysis, team scheduling and invoicing based on timesheet entries and expenses.
HAL Project Management also supports project organisation, scheduling, task timeframes, team allocation and comparison of project planning information with actual timesheet data.
Connecting these areas can reduce the need to repeatedly move the same time information between separate spreadsheets, project records and billing processes. The system still depends on employees using the correct projects and activities, managers reviewing submitted time, and the business applying appropriate costing and billing rules.
A useful project timesheet answers more than how many hours somebody worked. It shows where the time went and what the business needs to do with that information next.
When project and task codes are clear, entries are made consistently and submitted hours are reviewed, timesheets can support labour costing, resource planning, client billing and planned-versus-actual project analysis.
HAL Timesheets connects project hours with wider resource, project and invoicing workflows. Book a HAL demo to explore how HAL can support time tracking and project management across your business.
A project timesheet records the time a person spends on specific projects, tasks or activities. It helps businesses allocate working hours to the work that consumed them rather than recording only overall attendance.
Common fields include employee, reporting period, project, task or activity, date, hours, billable status where relevant, work description and approval status. Additional fields should be added only when they support a genuine business requirement.
Attendance records whether and when an employee worked. A project timesheet allocates those working hours to particular projects and activities. The two records can be connected but serve different purposes.
There is no universal frequency. Weekly submission is common, but the appropriate cycle depends on project reporting, billing, payroll and management needs. The key requirement is consistency and sufficiently timely entry.
Approved hours can be multiplied by an applicable labour-cost rate and allocated to the project or activity that consumed the time. The organisation needs to determine how its internal labour-cost rate is calculated.
Yes, where the customer agreement permits time-based billing. Approved billable hours can support invoicing using the agreed customer rate. Fixed-fee and milestone projects may use timesheets mainly for internal cost and profitability analysis instead.
Not by themselves. Timesheets record effort and time allocation. Productivity also depends on output, quality, task complexity, scope, working conditions and other factors, so hours should not be interpreted as a standalone performance measure.
