Which of the following can also be assigned as a source of supply for a purchase requisition?

The assignment of a source of supply for a purchase requisition in procurement processes is typically associated with formal agreements that outline the terms of purchase. A contract serves as a legally binding agreement between a buyer and a supplier, detailing the terms, conditions, pricing, and obligations each party has regarding the purchase of goods or services.

In the context of a purchase requisition, having a contract allows the organization to secure best pricing, guarantee supply, and ensure compliance with procurement policies. Contracts are crucial for maintaining a clear expectation of delivery, quality, and service levels, which are essential components of effective procurement practices.

On the other hand, proforma invoices and credit notes are typically financial documents that deal with billing and payment rather than the initial supply arrangement. A proforma invoice is a preliminary bill of sale sent to buyers in advance of a shipment or delivery of goods, while a credit note acts as a document that acknowledges a reduction in the amount owed, often due to returns or discounts. Supplier lead time relates to the time it takes for a supplier to fulfill an order and does not constitute a source of supply in the context of purchase requisitioning.

Thus, assigning a contract as a source of supply for a purchase requisition is entirely appropriate and aligns
