Hi juanita-montalvo,
I'm glad to see you're using QuickBooks Online's multi-currency features to streamline your international invoices. It's a convenient way to record transactions in foreign currencies, while taking advantage of powerful exchange gains/losses calculations. To ensure consistent reports and accurate tax filings, income and expense amounts are tracked in their home currency value. This is automatically displayed when you create an invoice so you'll always know how something will affect your books. The conversion is entirely for your own books and won't be visible to your customer. You can verify how the invoice will be displayed by selecting Print or preview.
I'm here for you. Feel free to reach out any time you have questions.
