I'm pleased to have you here, @safeer. Let me give you an overview of the Budget vs. Actual report in QuickBooks Online (QBO).
The report is set to display the Income first before the Expenses. If you have a different arrangement of accounts, you can re-sort it by following these steps:
Open the report.
Click on the drop-down menu under Sort.
Select either:
Default
Total in ascending order
Total in descending order
Tap on Run report to refresh the page.
Here's an article you can use as a reference for more tips while running basic reports in QBO: Run reports in QuickBooks Online.
