Can someone explain the use of Reports>>Sales And customers>> Deposit Detail???

I'm here to share information about the Deposit Detail report in QuickBooks Online (QBO).

The Deposit Detail report shows all of the deposits you've entered along with the date and the amount. You can also filter it to see the linked name (either customer or vendor).

You can use this report to easily track all the deposits entered in your program for a specific time frame. 

For more details, check the Next steps: Manage bank deposits section of this article: Record and make bank deposits in QuickBooks Online.

Customising reports to include only the data you need is a breeze in QBO. Read this link for detailed guidance: Customise reports in QuickBooks Online.

I'm just around the corner to help if you have any other concerns managing your reports. Please don't hesitate to leave a reply below. Have a good one.
