The Source-to-Pay cycle is a term describing the collection of processes a company has implemented between placing a purchase order or similar means of communicating the purchase of goods or services and the payment for these goods or services. The span of processes involved depends on the supply chain configuration and process strategy, but is typically limited to S processes*:
- Replenishment of purchased materials, products, goods or services: S1
- Special order or Source-to-Order materials, products, goods or services: S2
- Engineer-to-Order parts, materials, products, goods or services: S3
* The processes listed are incomplete as the final step in the Source-to-Pay cycle is the actual disbursement of funds. This process is a Financial process outside of the scope of Source.
Alternative names include: Purchase-to-Pay, Procure-to-Pay.
