In any real negotiation, you will give concessions. The question is never whether you concede — it's whether you do it on purpose or give the store away. A concession is a tool when it's traded for something real and stopped at a known floor; it's a disaster when it's a reflex that signals the next one will come easier. Prep told you your floor; this is the discipline of staying above it.
Concede on purpose
Every concession should cost you something small and return something real. Move on price, and take a longer term, a bigger scope, or a faster signature in return. Give a softer term, and ask for a reference or a multi-year commitment. The shape of a good negotiation is a series of swaps, not a one-way slide down your price list.
Know your walk-away price — and mean it
Your walk-away price is the line below which the deal isn't worth signing — the price and terms where the margin, the risk, or the precedent costs you more than the win is worth. Set it before the call, not in the heat of it. When a buyer pushes below your floor, the professional move isn't to cave — it's to calmly decline the terms and see if the deal can come back up. Buyers who know you can walk away respect your price more.
This isn't the same as qualifying out
Walking away here isn't qualifying out of a bad deal early — that's spotting an unqualified opportunity before you invest. This is holding your line on a real deal you want, protecting margin and integrity through the final negotiation. Both protect your quota; one protects your time, the other protects your value.

You can trade concessions and hold your floor. One more layer of the negotiation runs through a professional whose job is to squeeze you — negotiating with procurement.
