Also known as: POA

A purchase order acknowledgement is a supplier's confirmation that it has received a purchase order and accepts, or proposes changes to, its terms.

When a supplier receives a purchase order, an acknowledgement (POA) tells the buyer whether the order is accepted as issued or with amendments — for example to price, quantity, lead time or delivery date. It turns a one-sided order into a mutual understanding and gives the buyer early warning of any discrepancies before goods are produced or shipped.

Acknowledgements are valuable for planning because they confirm expected delivery and highlight problems while there is still time to react. In electronic ordering, a POA is often exchanged automatically, updating the buyer's system with confirmed dates and quantities. Comparing the acknowledgement to the original order helps catch mismatches early and keeps downstream matching clean.

Key points

  • Confirms the supplier received and accepts (or amends) the order.
  • Flags changes to price, quantity or delivery before fulfilment.
  • Often exchanged automatically in electronic ordering.
