Hi there, @brookehern10.

Thank you for posting in the Community. I'd be happy to help share some insight into how the company name shows on the email message sent with the invoice.

The default company name that shows on the sales forms, like an invoice and purchase orders is based on what is in your Account and Settings. As a workaround, you can temporarily edit the information before sending the email. After that, you can change it back to the correct company name.

Here's how:

1. At the top right, choose the Gear icon.
2. Select Account and Settings.
3. On the left pane, select Company.
4. Click the Company name section.
5. Edit the information in the Company name field. 
6. Click Save.
7. Select Done.

The following article contains more information about this: Change company name, address, email address, EIN, and privacy settings.

That should point you in the right direction today. Drop me a comment below if you have any other questions about managing invoice emailed to customers. I'll be happy to help you out. Have a great day ahead.
