Thanks for coming to the Community. I'm here with some insight to provide about sending invoices from QuickBooks Desktop.
I think it's a great idea if we can set up QuickBooks to email invoices depending on the Ship To address. At this time, QuickBooks uses the customer's email address as the basis on where to send your invoices. For more information about this, you can check out this article: Set up email service
Please let me know if there's anything else I can help you with. I've always got your back. Thanks again for dropping by, wishing you all the best.
