Dear gandhiapaq,

Good day ! i'm here to help :)

The exchange gain or loss in QB is recognised via the exchange rate field in the vendor invoice. For example, when we record the vendor invoice at a rate of 1:1.5 and subsequently, we record the payment at 1:2.0, there will be an exchange gain or loss based on the vendor invoice value X the difference in exchange rate (0.5 difference here).

We can avoid the exchange gain or loss by making sure the exchange rate is the same for the invoice and payment. To do this, we open the payment transactions, and edit the exchange rate to be the same as the vendor invoice exchange rate. The exchange gain or loss will be cancelled/removed.

Thanks
