How do I add or setup email address so that I get a copy of all invoices issued? and also how do I change from email QBO std email to my co name?

Let me guide you on how to set up your email address in QuickBooks Online (QBO), info1082.

We can go to the Account and Settings page to set up the email for Company email where QuickBooks can contact you. Then, add the email for Customer-facing email where customers can contact you shown on sales forms. Let me show you how: 

1. Go to the Gear icon on the top menu. 
2. Choose Account and Settings.
3. Select Company from the left menu.
4. Enter the email address in the Company email and Customer-facing email section. 
5. Hit Save.
6. Press Done.

To learn more about this one, see the Change company name, address, email address, and privacy settings article. You can use your Gmail address to send invoices in QBO. Also, you can send an email to multiple email addresses by doing either of the following:

• Typing in multiple email addresses separated by a comma and space.
• Using the Cc (carbon copy) or Bcc (blind carbon copy) fields.

Feel free to visit our Sales and customers page for more insights about managing your company's income and customers.
