Record the final terms of the trade

Before completing the trade, summarise:

• item A;
• item B;
• agreed values;
• cash adjustment;
• who pays it;
• included accessories;
• disclosed defects;
• delivery method;
• any conditions still to be checked.

The text does not need to be complex; it needs to be unambiguous.

If the negotiation takes place on Muviber, keep these details in the main conversation.
