If your business operates in multiple currencies, the first step to set your base currency. Follow the procedure in another Guide.
Once you set your base currency, forms and reports will include the symbol for it. By default, all existing accounts and subaccounts will be denominated in the base currency. When you edit these or create new ones, you will have the option to select other currencies. You can set foreign currencies in the following tabs:
Most transactions will adopt the currency applicable to the account or subaccount they relate to. For example, when you set a foreign currency for a customer, all their invoices, credit notes and quotes will be denominated in that foreign currency.
Some tabs, such as Expense Claims or Journal Entries, allow you to specify the foreign currency on a transaction level. For example, under Expense Claims this is useful when an employee is to be reimbursed in the base currency but the expense was incurred in a foreign currency.
