Hi there, @FulingSean.

Thank you for getting back to us. Let me help you send sales orders to different email addresses from an invoice. You'll need to manually enter the email addresses to whom you want to send the sales order and invoice.

Here's how:

1. Create or open a Sales order transaction.
2. Fill up the necessary details.
3. Click on Email.
4. Enter the email address in the To field.
5. Select Send.
6. Convert the Sales order to invoice by selecting Create Invoice.
7. Double-check the necessary details and click Email.
8. Enter another email address in the To field.
9. Select Send.

With QuickBooks Desktop, you can also create and send customer statements, providing a clear overview of their invoices, payments, credits, and balances.

Let me know if you have questions other than sending different email addresses from sales order to invoice. I'd be glad to help you anytime. Have a great day!
