If a discount is offered by a vendor as part of the submission, the
Procurement Officer/Assistant shall carefully consider the rate of discount and the applicable time limit in order to determine whether the discount is cost-effective and can be realistically availed of within the period specified by the prospective vendor. The payment discount period is a consideration in the Contract award. All other things being equal, the longer the time limit for obtaining the discount, the more attractive the discount will be to the UN.

The solicitation documents shall state, as applicable, that any payment discount period shall begin to run from the date of the delivery of the goods or services, or the date of receipt of a proper invoice, whichever is later.

If Authorized Costs Exceed
If the actual cost of goods, services or works being procured exceeds the estimated cost of the procurement, or some maximum amount set by the Requisitioner, the Procurement Officer/Assistant shall inform the Requisitioner thereof and request further instructions. The award shall be withheld until receipt of an amendment to the Requisition to increase funds or cancellation of the Requisition. If the interests of the UN indicate that the requirement needs to be reduced or changed, the Procurement Officer/Assistant shall seek authorization as to how to proceed.
