There isn't one right way to log time, and forcing the wrong one on a team is a fast way to get incomplete or inaccurate timesheets. Two entry modes cover most real-world workflows: the weekly grid and the timer.
The weekly grid
A spreadsheet-style layout — click a cell, type hours, tab to the next day — with daily and weekly totals updating live and auto-save so nothing's lost. This fits teams whose hours are predictable and known at the end of the day: office staff, salaried workers, or crews who already know how many hours a job took without watching a clock run.
The timer / stopwatch
Start a timer when work begins, stop it when it ends. This fits people who move between tasks throughout the day and would otherwise have to reconstruct their hours from memory at the end of the week — service techs jumping between tickets, or anyone whose day doesn't have a clean start and stop time.
Or both
Company Settings can allow grid entry, timer entry, or both at once — some businesses let office staff use the grid while field techs use the timer, and both feed the same weekly timesheet and the same approval workflow.
How to decide
If your team already knows their hours at day's end, the grid is faster and requires no discipline mid-day. If hours are only accurate when captured in the moment — multiple short jobs, unpredictable schedules — the timer will produce more accurate numbers than anyone's memory will at 5pm on Friday.
