How to I add a header image or logo to my Order Invoice?
Visit Admin > Layout
On the left column (under Admin heading) click on either Invoice PDF (or Invoice PDF 2, Invoice 3, Invoice 4, Invoice 5 and Invoice 6).
Here you can upload an image to the header or footer. In addition, you can add header and footer text on this page. (In this example below, we have upload a header image).
You can test how your Invoice PDF appears to your customer, by clicking on any order and emailing yourself a test invoice. View the attachment, as shown below. (In the example below, we selected to view our default layout – Order Invoice).
