Tenderer shall submit end-user acceptance certificate(s) as supporting document of the experience. Notification of Award (NOA) or Work/Purchase Order (WO/PO) alone will not be accepted (as they do not prove satisfactory delivery of the Goods and acceptance by the client/end-user), but may be accepted if supported by delivery challan (received and accepted by the client/end-user) or R&I (Receive & Inspection) report. However, delivery challan or R&I report alone may be accepted if pricing information of the supplied goods is mentioned.
