The Government has issued our company an RFP for Services. In the RFP, the CLIN for travel and MATERIALS is stated as NON-FEE Bearing. Our firm does not include Fee on travel and freight charges. Our firm's position on materials is that FEE on materials is appropriate. Do we simply take exception to their request on the basis of operating principle or does the FAR allow Fee to be applied appropriately? Any feedback to this situation is appreciated! Many thanks!
