Hi there, @lynnhagerman. I'm happy to help.

We need to input your email address into the Company Info section and the Customer contact info so that your clients or customers will see it as the sender when invoices are sent.

Here's how:

1. Log in to your QuickBooks Online(QBOA) account.
2. Click the Gear icon in the upper-right corner.
3. Under the Settings, select Company settings.
4. In the Company Info section, enter your email address.
5. Scroll down to the Customer Contact Info section to add your email in the Customer contact info.
6. Once done, click Save, then click Done.

Please respond to this thread if you need further assistance in setting up email address in QBOA.
