Within Preferences you can set your default mileage and travel unit:
- Mileage rate: This is your rate per mile/kilometre, the figure will always be the currency already pre-selected in Company Settings. Click on the field to enter the rate, this gives you the option to enter a rate with 4 decimal places.
- Travel unit: To select your preferred travel unit, tap on the small down arrow to select KM or Miles.

If you need to change your mileage rate for a one-off project or client, you can do this as and when needed when creating or editing your mileage item within the app itself.
