Why teams stop using spreadsheets for time tracking

Spreadsheets are the default starting point for almost every team tracking hours. They're free, flexible, and everyone already knows how to use them. For a team of two or three people, that's usually enough.

The cracks start showing once a team grows past a handful of people. Someone forgets to fill in Friday. Someone else copies last week's tab and forgets to clear the formulas. A manager asks 'how many hours did we bill client X last month' and the honest answer is 'give me twenty minutes.'

The underlying problem isn't the spreadsheet software — it's that a spreadsheet has no idea what a 'day' or a 'running timer' actually is. It can't stop you from double-booking an entry, it can't tell you a timer has been running for 14 hours because someone forgot to clock out, and it can't give an employee a view of only their own hours without a separate tab per person.

A dedicated timesheet removes all of that by construction: one clock running per person, one place entries live, and totals that are always correct because they're computed, not typed in.
