Here are some of the provisions which I have found lurking in purchase orders (a “PO”):
1. The P.O. replaces every provision in the vendor’s quotation and invoice.
2. The provisions of the P.O. include terms set out on the purchaser’s website, which the purchaser may change at any time. All changes will be binding on the vendor. It is the vendor’s responsibility to monitor the purchaser’s website to see which new terms have been imposed on it.
