Hi there, @Mark.

I will guide you on how to find the report in QuickBooks Desktop that shows income by customer with their zip code or city.

To show the zip code or city in the income by customer report, you have to customize it. Here's how:

1. Go to Reports and select Company & Financial.
2. Find Income by Customer Detail
3. Select Customize Report
4. Under the Display tile click on Search Columns
5. Type Name Zip to show the zip code and Name City to show the city name of the report and click OK
6. To ensure that the report is displaying the latest information, kindly click on the Refresh button
