No Purchase Order (PO), No Pay
No Purchase Order, No Pay, usually No PO, No Pay, is a business policy that refers to the practice of not paying a vendor or supplier for goods or services delivered unless a valid purchase order (PO) has been issued and authorized by the purchasing department or authorized personnel. This policy is intended to help prevent unauthorized purchases or invoices, reduce the risk of fraud, and ensure that all purchases are approved and tracked according to company policy. Essentially, it means that payment will not be made unless a valid PO has been created and approved.
In many jurisdictions, the policy can fall foul of common contract law and would not be upheld in court.
