The supply manager is responsible for resolving discrepancies in the procure-to-pay process. This includes ensuring that the quantities received match the quantities ordered and invoiced. While the receiving department records the receipt of goods, the supply manager must coordinate with accounts payable and the supplier to investigate and resolve any issues such as incorrect system entries or shipment discrepancies.
