Hi,
You can edit your HikaShop emails in the menu System>Emails.
There, you'll find the "order status notification" email which is sent when the order goes from "created" to "confirmed".
For each email, you'll see the "CC" field that you can use to add an email address which will be included in the CC of the email sent to the customer.
Please note however that this email is also sent to the customer when you change an order manually to another order status and you check the "notify user" checkbox. If that's something you need to do, then you would have to click on the "per status override" button of the "preload" section and there you can select the status for which you want the override and then add a bit of PHP code to add the cc manually:
where XXXX is to be replaced by the email address you want in CC.
