Hello dear I need to show the total amount of invoice with two currency how can i do that Thank you

Hello and welcome to the Community, kha93ahm.

I've got just the steps you'll need to show the total amount of both currencies on an invoice. If it's the first time you'll create an invoice with more than one currency, then you'll need to turn on the Multicurrency feature in QuickBooks Online. Please keep in mind that you can only turn on multi-currency for new customers. For customers that are already in your QuickBooks, "This customer pays me with" option is greyed out.

To turn on multi-currency:

1. Go to the Settings icon and select Company Settings.
2. Select Advanced and in the Currency section, click Multicurrency.
3. Check the box labeled Multicurrency to turn this feature on. Note: Once multicurrency is turned on, the home currency is set and cannot be changed in QuickBooks Online.
4. Click Save, then Done.

Once turned on, you need to set up your customer for multicurrency. Whenever you create invoices, it will automatically detect its currency.

1. Go to the Sales tab and select Customers.
2. Click New customer.
3. Fill out the Customer Information window.
4. Click the Payment and billing tab.
5. Click on the drop-down under This customer pays me with, and select the correct customer currency.
6. Click Save.
