From within the Billing Settings page, you can change your account settings so that time entries are automatically rounded up whenever you create an invoice.
You can round up to the nearest 5, 10, 15, 20, 25, or 30 minutes. For example, a time entry of 2h 10m would round up to 2h 15m when added to an invoice if the Time Entry Rounding was set to 15 minutes.
โ ๏ธ Note: The Billing feature is only available for US-based accounts at this time.
To setup time rounding, do the following:
Click Settings under Billing
Scroll to the bottom of the page on the Payments tab
Select the desired round time up value and click Save Rounding Settings
Anytime you create an invoice from the Unbilled page, the billed quantity will be rounded up based on your settings.
