Setting up the company's email address you use for sending invoices in QuickBooks Online (QBO) is pretty easy.

Here are the steps:

1. Click the Settings icon at the top and select Account and Settings.
2. Choose Company and click the Pencil icon on the Contact Info section.
3. Enter your email address in the Company email field and put a checkmark on the Same as company email.
4. Click Save, then Done.

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