You can customize the invoice (or receipt) design in the Configuration -> Invoice dialog. You can edit the HTML code representing your invoice here and use special expressions to insert dynamic parts of the invoice. For example, you can use the ##BILLINGADDRESS## expression to insert the customer's billing address into the invoice. You can find a complete list of available dynamic expressions at the bottom of the dialog.
This section allows you to attach a file to each autoresponder e-mail, such as event agenda, white papers, etc. When a file is uploaded in the field, two icons are displayed next to it:
|•||Edit () - if the file is an image, clicking the icon opens it in the built-in image editor. If the file is not an image, the metadata editor is opened after clicking the icon.|
|•||Delete () - removes the file from the field.|
