Thanks for getting back to us, stephentilerllc.

I've got the steps on how to change the company email that you use for your sales forms. Changing or updating the company email you use for sending invoices in QuickBooks Online is pretty easy. I'll show you how:

1. Click the Settings icon at the top and choose Account and Settings. 
2. Select Company on the left panel then click the Pencil icon on the Contact Info section.
3. Enter your new email address in the Company email field and make sure to put a checkmark on Same as company email.
4. Click Save, then Done.
   

Moving forward, the system will apply the new email address for your sales forms.

For future reference, I'm also including these articles you can check for further guidance:

• How to email or print an invoice
• Change the email address you use to sign in
