With QuickBooks Online, you can export your reports to Excel and take advantage of the built-in features of the spreadsheet-editing software. By doing so, you can get the totals you need without manually doing the calculations. For this specific situation, I suggest doing as follows:
- Select Reports from the left menu
- Scroll down to the Expenses and suppliers section
- Select Transaction List by Supplier
- Customize the report to show the transactions you need for each supplier, if needed.
- Once done, select the Export icon (see attached screenshot)
- Select Export to Excel
- Select Open with Microsoft Excel
- Find the Amount column and execute an AutoSum for each supplier
