Hey there, qbo2.

Allow me to provide additional information regarding adding a class to the Exchange Gain Or Loss account in QuickBooks Online.

Adding a class to the Exchange Gain Or Loss account is currently unavailable in QuickBooks Online. The Exchange Gain Or Loss is calculated once the payment is applied. You can only assign a class in the invoice and not at the time of payment.

These articles are a good reference:

• Frequently Asked Questions about Home Currency Adjustments.

• Differentiate Cash and Accrual basis.
• How to set up and use class and location tracking.
