Hello there, roger.

When you run both reports in QuickBooks Online (QBO) within the same date range, there shouldn't be a discrepancy between the two. 

You'll need to run a cash Balance Sheet and Statement of Cash Flow report with the dates aligned together to locate the entries making a disparity.





Also, check out this resource for more information on how to personalize the data reflected in your reports: Customize reports in QuickBooks Online.

Should you have follow-up questions or need further assistance running specific reports in QBO, feel free to notify me by leaving a reply below.
