Acceptance of the order in CERN’s e-Procurement platform. 

In case the acknowledgement of receipt differs from the date indicated in the purchase order, contact the Procurement Officer and, together, decide whether to maintain the existing delivery date or accept the change and amend the order.

Tips:  Acknowledging a delay does not mean that it is accepted as contractual penalties may still apply as of the original delivery date. In this respect, if necessary, the Technical Officer should consider maintaining the initial delivery date to maintain pressure on the Contractor and be delivered as soon as possible. The Technical Officer should not accept a new delivery date without having priory discussed with the Procurement Officer.
