It's time to track your mileage usage:

Open TEAK and create a new Auto Mileage entry for your client. Because TEAK's "drop-down" displays the last entry you made, all you need do is change the task, enter the mileage and a billing description.

And if that seems fast, wait till you use the option to have your previous stop mileage appear in the start mileage field. Either enter the stop mileage or the miles traveled and you're done!!
