Hello there, @luvdogs914.

Thank you for posting and sharing your experience while working with invoices in QuickBooks Online (QBO).

If you're referring on the name that reflects when printing invoices, you must have checked the box beside Use display name under the Customer information to show the display named used. Let me show you how:

1. Click Sales at the left pane.
2. Select Customers.
3. Select a customer in the Customers page.
4. Click Edit beside New transaction.
5. Under the Display name as column, type in the display name you want to appear on the invoice.
6. On the Print on check as, put a check-mark on the box beside Use display name.
7. Click Save to save the changes.

That would display the display name used while printing invoices. If you're referring to something else, feel free to let me know. I'd be glad to help!
