What should a purchase order contain?

The supplier, the ship-to location, and the terms; then every line with SKU, description, quantity, unit cost, and required delivery date. Add the incoterm, the currency, the payment terms, and any packaging or labelling requirements. Anything left implicit becomes a discrepancy when the goods arrive.

The required date is the field most often left vague. A purchase order without one cannot be late, which means supplier reliability cannot be measured and lead-time variability stays invisible.
