Hi peter-halpenny,

Thanks for getting back to us here.  In addition to the information provided above, it's important to understand how QuickBooks Online uses exchange rates.  for additional clarification, I recommend speaking with your accountant.  If you don't have an accountant, we can help you locate a ProAdvisor in your local area.
