I'm here to help you with updating your company address, @beatrice-goh.
The company address change will only be applied to newly created invoices. If you're printing those previously created invoices, you may need to change them manually.
First, let's ensure the company address is updated on your Account and Settings page as well as the template.
Here's how to review the address in the Account and Settings:
Go to the Gear icon, then select Account and Settings.
Pick Company from the left panel.
Select the Address pencil icon and update the Company address.
