a.r.o. meaning stands for “after receipt of order,” which is a term used in business and shipping to specify that certain actions or processes, such as order fulfillment or delivery, will begin only after the order has been officially received or processed. This term is commonly used in supply chain management, particularly in reference to lead times and the timing of shipments or deliveries. It is often seen in shipping terms or contract clauses where delivery or production schedules are contingent upon order confirmation.
