Good day, ruthjb.

You can pull up and print the Expenses by Vendor Summary report in QuickBooks Online (QBO). This report will show you the last categories used for a specific vendor.

Here are the steps:

1. Go to Reports.
2. Enter Expenses by Vendor Summary in the search field and click on it to open.
3. Set the date under the Report period.
4. Then, click on Run report.
5. Locate the vendor and click on the amount to open the Transaction Report page.

I've attached some screenshots for reference.

I'm linking an article that will help you in the future: Vendors overview.

Reach out to me if you have any follow-up questions. I'm here to help further. Have a great day.
