Sales negotiation
After a sales call, the salesperson sends an email “to confirm what we agreed” that locks in the discount obtained in exchange for a volume and a duration commitment. The client confirms without objecting, securing the counterpart.
Send the recap within the hour, tying each concession to its counterpart. Phrase it so that the other party's silence counts as acceptance.
Fixes the counterparts before the other party forgets them; creates an enforceable basis for the order.
An overly slanted recap is spotted and corrected point by point, which can reopen settled matters.
