Hello there, @oldtimberfloors.

You can connect a Google account to send forms from a Gmail address in QuickBooks Online (QBO). This way, your customers will receive one from a different email. Let me show you how.

QuickBooks send forms, like invoices, using the default email address (quickbooks@notification.intuit.com). However, you can add a Gmail address and let your customers receive them through it. To do this, let's go to the Send email window. Here's how:

1. Go to the Sales menu.
2. Open an invoice.
3. Make sure the customer's email is entered in the Customer email field and select the Save and send option below.
4. Click the From drop-down arrow and select the + Add Gmail address option.
5. In the Send invoices from your Gmail address window, click the Connect Google account button.
6. Follow the on-screen instructions to complete the process.

Once you're done, select your Gmail address in the From field while in the Send email window before sending.

Also, you may want to check out this article as your reference to guide you if you need to change what email address appears on your sales forms in QBO: Change the email address your customers see in QuickBooks Online.

Let me know if you have other concerns about sending forms and managing income transactions in QBO. I'll gladly help. Take care, and I wish you continued success, @oldtimberfloors.
