You can let your software create the linked exchange account for you or you can specify one yourself. To create an account yourself, see ‘Set up accounts’. You will need to select the correct currency and exchange account in the Account Information window.
If you plan to track unrealized gains and losses, you need to create an income account for this purpose. You may want to name it ‘Unrealized Currency Gain/Loss’ or something similar. We recommend that you consult your accountant to determine whether your business needs to track unrealized gains and losses and, if it does, the most appropriate way for it to do so. See ‘Tracking currency gains and losses’ for more information.
