Free Mechanical Engineer Timesheet Template
Mechanical engineers working on a fee basis need to track time accurately across design, analysis, testing, and reporting activities, each of which involves different levels of expertise and complexity. A timesheet that links hours to specific systems or components helps clients understand where engineering effort is focused and supports monthly fee invoicing. It also provides essential data for project cost management and post-project profitability review.

What should a mechanical engineer put on a timesheet?
A mechanical engineer timesheet records hours by project, system, and activity, with the date, the task, and the time spent. Note the project, whether the work was design, CAD modelling, analysis, or a review, and the system. System-level records support fee claims and let the practice track cost against each project.
Typical line items
- Date of work
- Project name or number
- System (HVAC, piping, equipment)
- Activity (design, CAD, analysis, review)
- Hours worked
- Billable or non-billable flag
- Staff charge-out rate
- Running total per project
How the work is charged
Mechanical engineers often work to a fee by project stage but log hours underneath to manage the budget and bill variations or extra analysis by the hour. Design reviews and workshops are usually recorded as their own entries.
Payment terms and deposits
A timesheet supports an invoice rather than collecting payment itself. Fees are commonly billed monthly or on stage completion, so keep entries dated and tied to the system for client review.
Tax and compliance
If you are registered for sales tax or VAT, that applies on the fee invoice the timesheet supports, not the timesheet itself. Confirm the rules in your jurisdiction.
Frequently asked questions
How should I describe engineering calculation work on a timesheet?
Reference the specific system, component, or standard being applied. 'Pressure drop calculations for cooling water circuit in accordance with EN 13480' is far more useful than 'calculations'. This level of detail also makes your timesheet a valuable technical record for the project.
Should I bill for time spent in design review meetings with the client's engineering team?
Yes. Design reviews are a critical part of the engineering process and require substantial preparation and active participation. Log the meeting time and any associated preparation or follow-up actions as separate entries.
How do I handle overtime or weekend work on a client project on my timesheet?
Log the hours on the day they were worked. If your contract includes a premium rate for overtime or weekend work, note this in the rate column or description. Clients on fixed-fee contracts may not pay a premium, but recording the hours still demonstrates the effort invested.
