On every order, you can view, edit, and add notes.
To do so, click on the order # to view the order details page. Add a note by typing in the Notes box.
Notes are visible to users on both sides of the order (i.e., both the buyer and seller can add, view, and edit the order's notes). You can continue adding notes and comments to orders even after the status has been updated to Delivered! 😃
Note: all notes are updated in real-time so there is no need to save your changes.
