Welcome to the Community space, @allislandsinspec.
You can edit your invoice email by clicking the Edit work info option. Let me guide you how:
- Log into your QuickBooks Self-Employed account.
- On the left panel, click Invoices.
- Click Create invoice or edit the invoice you've created already.
- In the Invoice, screen click Edit work info.
- Enter your email address.
- Hit Save.



In case you need to personalize your invoice details like Email, Design, etc. Just click the Customize settings on your invoice screen.
