# Timesheets

We call these **Sheets** in the product, not Timesheets, because a sheet doesn't have to be about time at all.

Most of the time (pun intended) a sheet is a collection of contiguous days and the number of time units being billed for on that day, plus some information on what was worked on. But the units billed can come from somewhere other than a clock, so "Timesheet" would imply an assumption the model doesn't make. A sheet has a status, may have attachments, comments and messages, as well as a history of actions, an audit trail and knowledge of the **Workflow**.
