Hi there,
Tracking locations in QuickBooks Online is a great feature that can help you keep track of your sales. It's essential that you're able to include each location in your Profit and Loss report.
To include all locations in your report, click the drop down menu under "Display columns by", which is located at the top left corner of the report under the reporting period. Select the "Locations" column. This is a setting that's accessed outside of the customization menu.
That's all there is to it! If you're still having issues locating this setting, please feel free to reach out in the comments below.
Have an awesome day!
