Welcome to the Community forum, NinaAlexander.
When updating email address on your QuickBooks Self-Employed (QBSE) account, it is not linked to the invoices.
Let me show you how to update the email address where the invoice is sent from. Here's how:
- In the left menu, click Invoices.
- Pick the Create invoice button at the upper right hand.
- Enter the necessary information.
- Hit the Edit work info link at the bottom.
- In the Your work info window, update the email address and Save.
- Choose Send invoice.
From there, you'd able to see what your invoice looks like. It will now show the email address you've recently entered.
