# Tags

A tag lets you group tracked records by something a [project]({{< relref "projects.md" >}}) alone can't capture — a client, a cost center, anything that cuts across several projects at once.

You can add tags to a record by hand, but it's usually easier to set them once on the project (or on one of its activities): every new record tracked there then picks up those tags automatically, with nothing left to remember.

The real payoff shows up in [statistics]({{< relref "statistics.md" >}}): filter by tag instead of project, and you can see exactly how much time went into a client or cost center, no matter which project it was tracked under.
