A standing purchase order is an approved order used for repeated purchases from the same supplier during a defined period. It sets the permitted goods or services, pricing or rate basis, spending limit, validity and release controls so individual recurring needs do not require a new PO each time.
When is a standing PO suitable?
It can suit predictable recurring requirements such as maintenance, consumables or scheduled services where the supplier and commercial basis are already approved.
What controls should it contain?
State the maximum value or quantity, covered items, locations, authorized requesters, release method, pricing, expiry, invoice instructions and owner.
Standing PO versus blanket PO
Organizations often use the terms similarly. Some distinguish a standing PO for recurring scheduled purchases from a blanket PO that sets a broad ceiling for releases. The document’s actual controls matter more than the label.
How are invoices managed?
Each invoice should identify the standing PO and applicable release or service period. Track cumulative usage and match the billed item, rate and accepted delivery.
What are the risks?
Broad descriptions, shared authorization, weak balance monitoring and automatic renewal can enable out-of-scope or duplicate spend. Close unused commitments at expiry.
