Start with the whole day.
Open a completed shift and look at its start and finish time, earnings and total miles together. The aim is to understand what happened across the day, not just the moments when you had a paying job.
Look between the jobs.
Follow the route and notice the stretches between paid journeys. Where did you reposition? Where did you wait? A strong fare can look different when you include the travelling around it. In Kerbi, the shift view separates jobs from between-job travel so you can revisit that context.
Give the costs a home.
If you paid for parking or a toll, add the expense to the relevant journey while the reason is fresh. Keep a note and the receipt together. A number labelled after logged expenses reflects what you have recorded; it is not automatically a complete profit figure.
Choose one thing to investigate.
A review does not need to become a spreadsheet session. Pick one question for the next shift: whether a return route was worthwhile, whether a waiting spot led to too much empty travel, or whether a certain part of the day deserves another look. One shift gives you a question; a longer history helps you test it.
