Hi there,
Keeping track of your expenses is so important, and it helps you better assess your business health. QuickBooks Online comes stocked with tons of helpful reports you can use to track your expenses. I'd be happy to suggest a report you can refer to.
I'd suggest running the Expenses by Vendor Summary Report. You can find it by clicking the Reports tab on the left navigation menu, then typing the title of the report into the search bar.
This report shows your total expenses for each vendor, and you're able to customize the date-range to display a certain time period you'd like to track.
You can get a more detailed look at each vendor's expenses by clicking the total expense amount from the report. This will display a list of all the transactions associated with the vendor.
I hope this helps you get back on track. If you're still in need of assistance, please touch base with our tech support team.
Have a great day.
