How to Void Order Tags

Would you able to provide any Customer account invoice template to send to customer email if any chance

You need to edit the Void Order State in Settings > States

Notice the <s> and </s> tags In my example I also changed the text to red. And changed the size and name format. etc.

There is no such thing.
The invoice would be the receipt from POS where you charge to account which would usually use the normal receipt/bill template.
From an account you would print statement, not an invoice.
