Thanks for reaching back out, 

The Transaction List by Supplier report will generate all transactions linked to each supplier in your QuickBooks Online account. The totals displayed in the Amount column are inclusive of tax, and if you'd like to see the tax breakdown, you can customize your report by clicking the small Gear icon, click Show More, and check off the box next to "Tax Amount". You can also select "Net Amount" if you'd like to see the total before taxes. 

Although this report doesn't generate totals, it will present the information in a clear and concise way so that you're able to add up each transaction manually. Otherwise, you can run the Expenses By Supplier Summary to generate the totals. 

I hope this helps clear things up for you. Let me know if you have any other questions. 

Cheers.
