I've got you covered, @joearaneta.

You can utilize the multicurrency feature in QuickBooks Online (QBO) to change the currency to an invoice if your customer uses different currencies. Here's how to set it up:

1. In your QBO account, click the Gear icon and select Account and Settings.
2. Go to the Advanced menu.
3. Select the Currency section and choose your Home Currency.
4. Turn on the Multicurrency checkbox, then confirm.
5. Click Save, then Done.

Once done, you can now add the currencies you use. Let me guide you how.

1. Click the Gear icon, then select Currencies.
2. Select Add currency.
3. From the Add Currency drop-down, choose the new currency.
4. Hit Add.

I'm adding this article for more guidance: Turn on and use multicurrency.
