QuickBooks maintains a Vehicle List and can track the mileage for those vehicles, as well as help to charge customers or clients for mileage recorded.
The Vehicle List tracks 3 simple pieces of information about a vehicle: the name, the description, and the active status.
To manage the Vehicle List, click on the Lists->Customer & Vendor Profile Lists->Vehicle List menu selection.
Click on the Vehicle button to add, edit, delete, or change the active status of list entries.
