Currency The account currency is the currency in which all journal entries for that account are recorded. By default, the currency is defined as All Currencies.
In an all currencies account, transactions can be executed in a foreign currency without the account’s foreign currency balance having any significance. Therefore, the account can accept journal entries in different currencies.
Example
A foreign sales account can be used for every sale abroad, even though the sales are in different currencies. Accounts are then settled with these customers in their account currency (an American customer buys in US dollars). However, the revenue account accumulates revenue from all the various currencies. Since this account is not a debit/credit account, its updated foreign currency balance is not relevant, and you refer only to its LC (local currency) balance.
End of the example.
If you work with a number of countries but use only one revenue account, define this account as All Currencies.
If the account currency is defined as a foreign currency, all postings in this account are recorded in both the local currency (as required by law) and in the defined foreign currency.
If you define a foreign currency account and record transactions for it, you cannot later change the account currency or perform transactions in any currency other than the defined account currency.
Accounts defined as foreign currency accounts are usually foreign bank accounts, and so on.
A foreign currency account has two balances: a local currency balance and the account currency balance.
