Purchase order management is an internal procurement process adopted by organizations to ensure that each and every purchase is necessary, justified and optimized for costs. Many organizations have well-established purchase order management policies to ensure that employees follow standard operating procedures before purchase orders are executed. Purchase order management also ensures that retailers maintain an audit trail, which can support better supplier relationships with increased transparency. Increased flexibility with suppliers is also facilitated by a purchase order management system, supporting flexible purchase orders: there is no need to re-raise orders for incomplete deliveries, as the system permits receipt of additional deliveries. As we move into the era of automation, automatic purchase order creation defaults can be set by user to speed up purchase order processing, as well as a copy function for faster processing of similar purchase orders.
