Which type of service Purchase Order is used when the service's full scope is outlined...

APlanned Service Purchase Orderis used when theentire scope and cost of the service is known upfront. The details of tasks, deliverables, and expected quantities are clearly defined and included in the PO. This allows for structured receipt and tracking of service delivery.

Unplanned services are used when details are not predetermined. Service Entry Sheets are related to service confirmation, not the PO type. Non-PO Service is a type of invoice, not a PO.
