# Going Plural

A sender can work for more than one client, through more than one agency, at the same time - and Zipwire is built around that being completely normal, not an edge case.

## One journal, many clients

The [journal](/zipwire-approve/unboxing-key-concepts/the-journal.md) is a single, private record that belongs to the sender, not to any workplace or agency. Whether someone works for one agency or five, they keep one journal and log their day-to-day work there just once, regardless of how many places that work ends up being billed to.

## Sheets are generated, not typed

Because the journal and the [sheet](/zipwire-approve/unboxing-key-concepts/timesheets.md) are deliberately separate things, a sender doesn't have to keep several different timesheets in step with several different sets of hours. They enter time once in the journal, tagged against whichever **Activity** it belongs to, and Zipwire works out which assignment - and therefore which client, workflow, and billing plan - each entry belongs to.

## Under the hood

When it's time to send, Zipwire doesn't produce one sheet from the whole journal. It walks the journal entries, groups them by the assignment each activity is linked to, and sends out a separate copy of the sheet for each one - each routed to the right approver and processor team, correctly filled out under that assignment's own billing plan. A sender working two agencies at once ends up sending two sheets from one act of journalling, without doing the matching themselves.

## Why this only works because the login is personal

Going plural isn't a separate feature bolted on top - it falls directly out of [data ownership](/overview/data-ownership-in-zipwire.md) in Zipwire. Because the account and the journal belong to the individual rather than to whichever agency set them up, there's nothing stopping the same person, the same login, and the same journal from serving several agencies at once, or picking up a new one the moment an old engagement ends.
