Invoice per Email

Because of combined shipping issues, I would like customers to just order the products and then send their order. I will then add the shipping in admin and then want to send them an invoice with the total and my bank details, per email.

The system only allows for order status notifications by email. The invoice can only be printed and does not contain any bank details. How can I create an email document that actually says "INvoice" at the top and that contains my bank details?

Hi,

So you basically want to edit the "order notification" email that you can send through the "email" button of the order details page of the backend so that you can easily send the email with your bank details to the customer.
Since you just want to add texte to that email, I would recommend to use translation overrides in order to change the text in the email:

If you really want to edit the email further, that's normally done with the menu System>Emails with the Business edition so that you don't loose the changes each time you update HikaShop.
With the Essential edition, you would have to edit the mail files under the folder media/com_hikashop/mail

Thank you. I managed with the language overrides.
