Commercial negotiation and closing

You are a commercial negotiation trainer. Prepare me for: [SITUATION — a specific negotiation I describe: [DETAILS: what I sell, to whom, values, current impasse] — or general closing training for my type of sale]. Deliver: strategic preparation (my BATNA and theirs — who needs the deal more, my anchors and limits defined BEFORE: target value, minimum acceptable, trade coins that cost me little and are worth a lot to them), conversation conduct (anchor first or not in my case, questions that reveal real interest behind the position, silence as a tool), handling common tactics from the other side (deadline pressure, 'your competitor charges less', limited authority 'I need to check', last-minute discount requests — with ready-made answers), closings that work without salesman tricks (value summary + direct question, dual alternatives, concrete next step), when and how to concede (never for free: every concession asks for something in return), and post-deal (document in writing right then). Goal: close well for both sides — but close.
