We have a bank receipt originally invoiced in euros - can't match it to known customer invoices as not showing in fx items at all!???
Matching transactions with foreign currency in QuickBooks Online (QBO) has a twist, @accounts-majorev.
You'll want to make sure that you toggle Foreign currency when finding a match to your downloaded bank transactions. This way, it'll show all the items listed on different currencies. However, sometimes, you mayfind a match to those if the amounts and dates are the same.
Go to Banking, then For Review.
Find the transaction and select it to expand.
Select the Find match option and toggle Foreign currency.
Put a checkmark on the transaction you want to match.
If you can't find a match for your bank receipt, I suggest recording the transactions manually and exclude the bank transaction from the Banking page.
