Hi there, Rebecasira.

I'm glad to see you here in the Community. Let me help you with the vendor report you need in QuickBooks Online.

You can try running the Expenses by Vendor Summary report to show all vendors and the expenses. Here's how to run the report:

1. On the left panel, click Reports.
2. In the search bar, type in Expense and click Expenses by Vendor Summary.
3. Below Report period, select Custom.
4. Enter the dates.
5. Click Customize.
6. Configure the rows, columns, and filters if needed.
7. Click Run report.

Please refer to this screenshot:

If there is information unavailable within the report, please know you can also export the data to Excel. From there, you'll be able to customize the QuickBooks data further.

As always, I'm available for any help you may need with the reports. You can get back to me by posting your response down below.
