PO (Purchase Order)

What is PO?

The buyer's binding order document referencing the agreed proforma invoice, quantities, prices, Incoterms and delivery window. Issue it against a signed PI so the two documents cannot drift apart — where they disagree, the dispute is usually resolved against whoever wrote the vaguer one.
