I understand the importance of having a comprehensive ledger report for your law firm's bookkeeping, @Marufa0013. Thanks for providing a screenshot. I'm committed to exploring potential solutions to address the best possible guidance.
To generate a comprehensive ledger report, we can run two separate reports: one for the client-side transactions and another for the office-side transactions. You can then export these reports to Excel and combine the data into a single spreadsheet.
To export your reports to Excel from QuickBooks Online and download your data from your account, please see these resources: Export reports, lists, and other data from QuickBooks Online. Here's more information on working with reports that may come in handy moving forward: Reports included in your subscription.
Regarding the specific format of the combined ledger report you've attached from LEAP, it may not be possible to have the exact same layout in QBO, but you can customize reports and combine the necessary information to achieve a similar overview.
If you need more information, I have added an article that explains how to memorize reports in QBO for future reference: Memorize reports in QuickBooks Online.
Rest assured that I am here to guide you in obtaining the best financial report that suits your specific needs within QuickBooks Online. Your satisfaction is my priority. If you have any further questions or additional details to share, please don't hesitate to reach out. I look forward to working with you to achieve the optimal solution.
