Choose to round up to next, down to previous or to nearest. For example, if you chose up to next and are using 30‑minute billing units, 10 minutes would be rounded up to 30 minutes on an activity slip. Or, if you chose to nearest and are using 30 minute billing units, 15 minutes would be rounded up to 30 minutes.

If you are not using a special billing unit of time—that is, you are billing in hours—you can specify the rounding increment. For example, if you want to round the actual time you clock using the timer up to the next minute, choose up to next and enter 1 in the Minute Increment field. That way, if you clock 21 minutes and 32 seconds of an activity, 22 minutes will be entered automatically in the Units field.

Note: If you specify a special time billing unit, the Minute Increment field will not be displayed as part of the rounding rule option.

Note that the I Sell This Item option must be selected in the Item Information window before you can include an item on a time billing invoice.
