Can I obtain a total dollar value spent from one particular customer?

Hi nellygirl11-outl,

In QuickBooks Online, the reports will always use your home currency regardless of the the currency used in the transactions. If you want to obtain the total dollar value for a customer, you can run a Transaction List by Customer report in your QuickBooks Online account and can customise the report to add Foreign amounts in the columns. 

Here's how:

1. Click on the Reports tab.
2. On the search box you can enter Transaction List by Customer.
3. Click on Customise to add row/columns and select Foreign amount.
4. Click on Run report.
