The Source-to-Pay (S2P) process represents a comprehensive sequence of activities that link an organization with its suppliers, initiating with the identification of suitable suppliers to meet specific needs, followed by negotiations and contract agreements for the acquisition of goods and/or services. This process concludes with the invoicing and payment to these suppliers. S2P also involves strategic procurement processes, including spend analysis, sourcing, contract management, and supplier management, which addresses supplier information, risk assessment, and performance evaluation, along with downstream tasks such as electronic procurement, purchase orders, invoice automation, and accounts payable operations. Organizations leverage the Source-to-Pay framework to minimize expenses, mitigate risks, foster innovation, enhance supplier partnerships, and achieve a range of other objectives.
