I need to have the invoice emails sent from my company domain. What is the process for authentication with my email server? I don't see any options...

Thank you for posting here on the Community page, divine.

I recognize the ability to set your company domain for emailing invoices in QuickBooks Online (QBO) would be helpful for you and your business. Currently, this option is unavailable in QuickBooks Online.  The invoice sent from QuickBooks comes from Intuit's service email addresses.

 As a workaround, you can download the invoice and then send it using your company's email domain.
 

At times, we roll out enhancements based on our customer's requests. That being said, I suggest sending a recommendation to our product developers. They'll review this idea and might consider updating it in the future.

Here's how:

1. Go to the Gear menu and then select Feedback.
2. Type in your feature request in the description box.
3. Once done, click on Next.

You can also track feature requests through the Customer Feedback for QuickBooks Online website.

I've added this article that will guide you in personalizing your sales forms: Customize invoices, estimates, and sales receipts in QuickBooks Online.

As always, add a comment below if you have any other questions about using and customizing your domain to send emails in QuickBooks. Have a great day.
