I'll share the steps to add an email using carbon copy (CC) or blind copy (BCC) in QuickBooks Online (QBO), sewhe1pme.

That is correct. The steps given above are for QuickBooks Desktop users. You can follow the procedure below for QBO to prevent entering it each time you create a sales form.

Here's how:

1. Go to Settings ⚙.
2. Click Account and Settings.
3. Select the Sales tab, then go to the Messages section.
4. Select Edit ✎, then enter the default email addresses in the Cc or Bcc.
5. Click Save, then Done.

Please see this article for complete details on how to email a sales form or report to multiple email addresses: Email a sales form or report to multiple email addresses.

You may also personalize the look by including specific information on your sales forms. Visit this link for additional info: Customize invoices, estimates, and sales receipts in QuickBooks Online.
