As its name implies, a procure-to-pay (or purchase-to-pay) system is a fully integrated solution designed to support an end-to-end process that begins with goods and services requisitioning and ends with ready-to-pay files for upload into an accounts payable system. Procure-to-pay solutions use a scan-and-capture service, supplier portal and/or a multienterprise network to enable suppliers to submit invoices electronically. In addition to core e-procurement functionality (including e-requisitioning, approval workflow and e-catalog management), procure-to-pay solutions offer purchase-order-to-invoice matching and processing for invoices that don’t match or when goods are returned.
