The posting feedback process is identical for both transaction partners (buyer and seller).
Go to the Feedback (Home -> Members Area -> Feedback Received) menu:

Important: Unless completing the Comments field, the feedback won't be posted.
The final screen will display a message confirming the posting of the feedback and the updated reputation (rank) of the buyer.
