how do I create an "Expenses by Vendor Summary" report

Hi there, @CrossGold.

Since you are using the international version of QuickBooks Online, have you tried running the Expenses by Supplier Summary report? If you haven’t yet, please know that the term Supplier is used instead of Vendor, which is likely why the report you were looking for didn't appear in the search results.

To find this report and get the totals you need, you can follow these steps:

1. Click Reports on the left menu.
2. In the search box, type Expenses by Supplier Summary and select it.           
3. Set the Report period dropdown to Last Financial Year.
