i want to display invoice amounts in both home and foreign currency.

The QuickBooks Online (QBO) invoices only display one currency during printing, James208. As this feature is unavailable, I recommend sending Feedback to our Product Development team.

Our Product Development team is committed to assessing your suggestions and improving the invoicing feature that includes both home and foreign currency in a single document. To send a feature recommendation, you can follow the steps below:

1. Click the Gear icon at the top, then tap Feedback.
2. Indicate your comments or suggestions.
3. Then select Next to submit Feedback.

Moreover, you can utilize the QuickBooks Online Feature Requests page to keep track of feature recommendations.

As a workaround, you can generate the Invoice List by Date report and customize it by adding the Foreign amount column to access details on both home and foreign currency invoice amounts in one place.

Additionally, refer to this guide on personalizing your QBO reports to maximize the effectiveness of your financial reports: Customise reports in QuickBooks Online.
