In a dispute, consider both sides of the trade

A dispute involving a trade can be more complex than one involving a sale.

To reconstruct the situation, consider:

• condition of item A;
• condition of item B;
• cash adjustment;
• any shipments;
• timing;
• changes made after handover;
• documentation from both parties.

Avoid improvised solutions that address only one half of the transaction.

If an official procedure applies to the transaction, follow it.
