Sales negotiation
After a negotiation video call, the salesperson sends an email “just to make sure I've noted everything correctly”, listing the price, scope and deadlines agreed, and invites the client to confirm, which they do, sealing the deal.
Send the recap while it is still hot and ask for explicit confirmation; the client's “yes” amounts to a commitment.
Freezes the agreement before the client reopens it and creates a consistency effect that eases signature.
A recap that inflates your advantages will be spotted and will reopen the whole discussion.
