The main difference between IDIQ contracts and BOAs is in competition. IDIQ meets requirements for competition at the time of initial award, but do not allow for participation by new contractors on additional delivery order awards.
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.
