# **Time tracking**

Time in tobbli lives on a project, not as a free-floating timesheet. Start the timer there, stop it, then pull unbilled hours onto an invoice.

1. **1**## **Open the project you are working on**

   Create or open a project under the client. The timer belongs here so hours, expenses, and documents stay on the same engagement instead of a global dump of time.
2. **2**## **Start the timer, then stop it**

   Start when you sit down, stop when you stand up. If you forgot to stop, edit the duration on the entry. The record is the hours you will bill, not a surveillance log.
3. **3**## **Find hours that are not on an invoice yet**

   Unbilled entries stay on the project until you pull them. Filter or scan for work that has not become a line item yet so a week does not disappear into a notebook.
4. **4**## **Turn those hours into invoice lines**

   From the project, add unbilled time to an invoice. Descriptions and quantities come from the entries — you should not retype the week in the document editor.

## **Why the timer is not on the invoice first**

Invoicing from memory is how hours go missing. Tracking on the project first means the invoice is a rollup, not a reconstruction. If you only ever send one-off invoices with typed lines, you can skip the timer — it is there when the week is too messy to remember.

## **Fixing an entry after the fact**

Adjust duration or notes on the time entry before you bill it. After hours are on a sent invoice, treat that like any other sent line: the document is locked, so a correction is a credit note, not a quiet edit of history.
