P2P = Procure-to-Pay A P2P system is a fully integrated and automated end-to-end business process, which starts with suppliers, continues with ordering and receiving, and ends with payment. The front end begins with suppliers who offer products and services at negotiated and contracted prices. A business then initiates the automated shopping and ordering process for food, operating supplies and equipment (OS&E), services, and furniture, fixtures and equipment (FF&E). The generation of purchase orders, approvals, receiving, invoicing and payment are processed in the system, which ends with approved to pay invoice vouchers that are integrated into an accounts payable or ERP system.
