To change business owner details, log in using the email address originally used to sign up to Sage (the business owner email).

Check the user settings to verify if you're a business owner. 

If you have access to the registered business owner email address, use that to log into your account:

1. From your profile dropdown in the navigation bar, select Manage account.
2. Select Manage profile settings, then select Continue to sign in (new tab).
3. Log in to Sage's account management area and select Personal details.
4. Edit the personal details and select Submit.
5. Enter the current business owner email address and password and then select Log in.
   You'll see a success message display to confirm the change.
