I need to send out invoices in more than one currency, but it says I can only choose one currency to invoice in, do you have to upgrade to get or do they just not offer?

Hello Jennifer, welcome to the Community page. I'm here to assist you with sending an invoice using multiple currency in QuickBooks Online.

Please note that this feature is only available on QuickBooks Plus and Advanced subscriptions. If you're subscribing to Simple Start & Essentials, I recommend upgrading it.

You'll need to enable multicurrency before sending the invoice to various locations. Be aware that once you turn on Multicurrency, there's no way to undo it.

To enable multi currency, follow these steps:

1. Access your QBO account.
2. Click on the Gear icon and select Account and Settings.
3. Select Advanced.
4. Click on the Edit button in the Currency section.
5. Choose your preferred currency from the Home Currency dropdown.
6. Check the Multicurrency box and acknowledge that you can't undo this option.
7. Save your changes.

Once done, you can proceed in sending invoices to your customers with different currencies.

Additionally, you can refer to this article to help you receive payment for your customer's invoices: Record invoice payments in QBO.

I'll be here to assist you further If you have more questions with managing your sales form in QBO. Have a wonderful day.

You should tun on multi-currency in QBO

When you add a new customer, you will have option to pick the currency.

All your existing customers will be assigned the home currency by default. You can't change the currency of existing customer so you will have to create new customers for different currency.
