Welcome to the Community, @usermaw.

In QuickBooks Online (QBO), you have the option to adjust your currency for foreign balances. These adjustments affect your balance sheet accounts.

Here's how to do it:

1. In QBO, go to the Gear icon at the top right to get to the Currencies. 
2. Locate the currency you want to adjust.
3. Click the drop-down arrow under the Action column, then pick Revalue Currency.
4. Enter the date, then select whether you'd like the revaluation to be based on the market exchange rate or a rate you specify.
5. Choose the account(s) you want to apply the revaluation to.
6. Hit Revalue to complete.
