quotes, and purchase orders or receive bills and payments in currencies other than
your own. Users can configure multiple currencies for the transaction, set its exchange
rate, and assign different currencies for individual partners and charts of accounts,
run reports on their foreign currency activities. Odoo will allow you to send sales
invoices, quotes, and purchase orders or receive bills and payments in currencies
other than the default/domestic currency. In the accounting module, Go to Configuration
