Timesheet rounding rounds each time entry to a set number of minutes when you bill it, for example to the next 15 minutes. Use it when you charge for time in fixed blocks.
The timesheet always keeps its original duration. Rounding happens when time is added to an invoice or a supplier bill, and in reports when you ask for it.
Set up rounding
Go to Settings › Timesheet Settings. Administrators, Finance Managers and Portfolio Managers can open it.
Under Timesheet Rounding, choose a method in the first list: round to the nearest increment, or round up to the next one.
Choose the increment, in minutes, in the second list. The change is saved straight away.

To switch rounding off, choose no rounding in the first list. The increment list then disappears. The setting applies to the whole account.
How each method rounds
- Round to the nearest: less than half an increment past a boundary rounds down, half or more rounds up.
- Round up: anything past a boundary rounds up. Timers record time to the second, so even a few seconds over can add a whole increment.
- Both methods: an entry shorter than one increment becomes one full increment. An entry of zero hours stays at zero.
With a 15-minute increment:
Time entry | Round to the nearest | Round up |
|---|---|---|
5 minutes | 15 minutes | 15 minutes |
20 minutes | 15 minutes | 30 minutes |
25 minutes | 30 minutes | 30 minutes |
1 hour 7 minutes | 1 hour | 1 hour 15 minutes |
1 hour 15 minutes | 1 hour 15 minutes | 1 hour 15 minutes |
Each entry is rounded on its own, before entries are grouped into invoice lines. Rounding up to 15 minutes, three 10-minute entries become 45 minutes, not 30.
Where rounding applies
- Invoices: time added with Add Time, recurring invoices that include unbilled time, and invoices created through the API. The invoice line shows the rounded hours. See why timesheets round up on an invoice.
- Supplier bills: time added to a bill is rounded the same way.
- Reports: the reports below have a rounding option, which is off by default. Tick it to see the hours as an invoice would show them.

Reports round with the setting as it is when you run them. Invoices keep the hours they were created with: changing the setting doesn't change existing invoices. So after a change, a report for an earlier month can differ from the invoices you sent then.
