When I send my invoices, a copy is also automatically sent to another email address I manage. Is there a way to stop this?

Welcome to the Community, -wwcairns-com-au.

Let me guide you on how to remove the other email address in getting the invoice copy sent from your QuickBooks Online account. Here's how to:

1. Click on the Settings icon.
2. Click on Account and Settings.
3. Select on Sales tab, and then tap the pencil icon under the Messages section.
4. Locate the Email me a copy at (your company email) section and remove email from CC/BCCC.
5. Click on Save and click on Done.

Once done, let's try sending a dummy invoice and verify if the other email address no longer shows or receive the invoice sent from QBO.
