Graceful Acceptance

"I appreciate you working with me on this. I am thrilled to accept at $X with [agreed terms]. Could you send the updated offer letter so I can sign today?" Always get the final terms in writing before celebrating — a signed document is what actually counts.

Never accept or reject an offer on the spot. "I would like a day to review this carefully" is always appropriate and buys strategic thinking time — cooling your relief at being chosen before it overrides your math.
