what is a timesheet - A timesheet is, at its simplest, a record of how much time someone spent working — broken down by day, task, or project — that gets reviewed and approved before it's used for payroll, client billing, or reporting. That definition hasn't changed much in decades. What has changed is almost everything about how a timesheet gets created, reviewed, and used once it's submitted.
This guide covers what a timesheet actually is, the different forms it takes, and how the shift to cloud-based software has changed what businesses can do with the data once it's captured.
What a timesheet actually records
At minimum, a timesheet captures who worked, when, and for how long. Beyond that baseline, most modern timesheets record a fair amount more:
- Which project or task the time was spent on, not just a total for the day
- Whether the time is billable, for organizations that invoice clients based on hours worked
- Overtime, when hours exceed a standard threshold for the period
- Remarks or notes, giving context a manager might need when reviewing the entry
The format varies by industry and company size. A retail employee's timesheet might just track clock-in and clock-out times against a schedule. A consultant's timesheet might break a single day into six different entries, each tagged to a different client and billable status.
Paper, spreadsheet, or software: the three eras of the timesheet
Timesheets have gone through roughly three phases, and a lot of businesses still operate somewhere in the middle of the transition.
Paper timesheets were the original format — filled out by hand, physically submitted, and manually entered into a payroll system by someone in HR. They work, technically, but every step is manual and error-prone.
Spreadsheet timesheets digitized the format without automating much of the actual process. Someone still fills in cells by hand, still has to remember what they worked on, and a manager still has to manually review and compile the data before it's usable for payroll or billing.
Software-based timesheets — increasingly cloud-based — automate large parts of what used to be manual. Time can populate from a running timer rather than being typed from memory. Approvals route automatically and escalate if nobody acts. Attendance and payroll data connect to the timesheet directly, instead of living in separate systems someone has to reconcile.
Why the software era matters more than it might seem
The practical difference isn't just convenience — it's accuracy. Ask someone to recall how they split their day across three tasks a week after the fact, and the answer is going to be an estimate, not a record. Employee time tracking that happens in real time, as work is done, produces meaningfully more accurate data than anything reconstructed later from memory.
That accuracy compounds. More accurate time data means more accurate client billing, fewer payroll corrections, and reporting that reflects what actually happened rather than what someone guessed at the end of the week.
How this connects to time and attendance cloud software
A timesheet on its own is just a record. Time and attendance cloud software is the system that captures, stores, and connects that record to everything else — attendance, leave, payroll, project reporting — without requiring manual work to link them together. If you're evaluating a platform and want the fuller picture on how the cloud-based version of this works, our companion guide covers it in more depth: What Is Time and Attendance Cloud Software?
What to look for if you're moving off paper or spreadsheets
- An employee timesheet template or default structure that's flexible enough for how your team actually works — daily totals for some roles, task-level detail for others
- A start/stop timer, if accuracy matters more than convenience for your use case
- Automatic approval routing, so timesheets don't stall waiting on one person
- A direct connection to payroll and attendance, removing the manual reconciliation step entirely
- Mobile access, for anyone who isn't submitting their timesheet from a desk
Where OfficePortal fits
OfficePortal's timesheet software covers the full progression from paper to cloud in one platform — daily or weekly entry, a start/stop timer for precise tracking, multi-level approval with automatic escalation, and a direct connection to attendance and payroll. It's free for up to 5 users, which makes it a reasonable way to test what a proper timesheet system actually changes versus continuing with a spreadsheet.
Conclusion
A timesheet hasn't changed much as a concept — it's still a record of time worked, reviewed and used for payroll or billing. What's changed is how much of that process can now happen automatically instead of manually, and how much more accurate the underlying data is as a result.
