Where do I change the from information on the emails of statements?

Good day, fdrko.

I can provide some information and show you how to change the from information on the customer's email statement in QuickBooks Online.

If you meant to change the email subject line for your customer statements, follow the steps below:

1. Go to the Gear icon.
2. Choose Account and settings.
3. Select the Sales tab, go to the Messages section, and hit the Edit.
4. In the Sales form dropdown, select Statement.
   
5. Make the changes in the Email subject line.
6. Then, click Save and Done.

Otherwise, if you want to change the customer-facing email or the email address that appears on your sales forms, you can use the following resources:

• Change your customer-facing email address
• Change the email address your customers see in QuickBooks Online

I've also added this article so you'd know how to personalize your sales forms:  Customize invoices, estimates, and sales receipts in QuickBooks Online.

Don't hesitate to leave a comment if you mean something else or have follow-up questions about statements. I'd be glad to help. Have a great week!
