Blanket PO: Designed for long-term agreements, typically spanning a year or a quarter, with defined start and end dates. It's suitable for recurring purchases where a continuous need exists. The contract length is a key differentiator. Standard PO: Used for short-term or one-time purchases to fulfill a specific order.
Blanket PO is used when a business has a long-term agreement with a vendor it purchases the same goods or services on a regular basis. A business uses Standard PO to buy goods or services on a one-time basis, or when it has a short-term agreement with a vendor.
