S2P is the complete process between an organization's suppliers and its customers. It begins with identifying the right suppliers to meet a need, then negotiating terms and signing contracts with them to receive goods or services. Invoicing and payment to suppliers is the last stage of the process. Source to pay refers to strategic procurement activities like spend analysis, sourcing and contract management. It also includes downstream activities like e-procurement and purchase orders. Invoice automation is an option. Accounts payable and payment processes are also included. The Source-to-Pay process is used by businesses to reduce costs, monitor, lower risk, improve innovation, strengthen suppliers relationships, and many other purposes. Ivalua's Source-to-Pay platform digitizes all aspects of the process, including all categories of spend and all suppliers.
