I would suggest you use this module https://drupal.org/project/commerce_invoice_receipt and then its very easy to modify what gets sent out.
Drop the 'commerce_invoice_receipt' folder into the modules directory '/sites/all/modules/'.
In your Drupal site, enable the module under Administration -> Modules '?q=/admin/modules'.
Setup new Commerce Order display under Store -> Configuration -> Order Settings -> Manage Display '?q=admin/commerce/config/order/display'. Click on the 'Invoice/Receipt' tab. Unhide any fields you want to use in your invoice.
Setup a rule under Store -> Configuration -> Checkout settings -> Checkout rules '?q=admin/commerce/config/checkout/rules'. Then 'Add a checkout rule', you'll find an action called 'Send invoice receipt email' under Commerce Order that you can use.
You can customize the rule to send out any info you need.
install this module https://www.drupal.org/project/commerce_message it will proivde access many type of messages along with their rules. You can configure and add your own message types
