Hi Kevin,

Yes, you can do that with a PHP code snippet. 

The snippet is:

add_action('b2bking_after_subaccount_created', function($user_id){
    $userobj = new WP_User($user_id);
    $userobj->set_role('editor');
}, 10, 1);

In the above, replace "editor" with any role that you want.

You can add the above to functions.php or by using our guide here https://woocommerce-b2b-plugin.com/docs/how-to-add-a-snippet-php-or-js/

Kind regards,
Stefan
