You could add notes to the order to save some administrative information along with the order. The customer won't be able to see the notes. Only store admins can view the notes. To add note to the order, go to the order detail page (refer to Edit Orders on how to get to the order detail page) and find "Add Note" button. Enter any note in the text box above the "Add Note" button. Click "Add Note" button to save the note.
