When vehicles are substituted, Peruvian auto dealers should pause payments related to the replaced vehicles until they receive an updated written order. The update should state the new vehicle VINs, specifications, condition, price impact, and delivery terms, and be confirmed by authorized representatives of both parties. Procurement personnel should also recheck the photos, draft invoice, and shipping records. If the change affects import arrangements, confirm the applicable procedure with a local licensed provider.
