Systems, methods, and processor-readable storage media for processing merchandise shipping are provided to ensure that a supplier fulfills a purchase order in a manner that will keep a supply chain filled with the product based on a demand. For example, when a purchase order is generated, a timer can be activated. Within a predetermined period, the supplier can confirm fulfilment of purchase order through an online platform. Based on this confirmation and historical data collected for the supplier, a shipping location and other shipping parameters can be predicted by the online platform. If the timer is expired and no supplier's confirmation is received or if the supplier denies confirming the fulfilment of purchase order, a default operation is initiated. The default operation may cause canceling of purchase order or communicating to the supplier to resolve any issues.
