Many times potential vendors are receiving RFP documents from third party, rather than direct government authority. If you are looking forward to submit your proposal for Solicitation then we will suggests you to register your company with Government Authority directly.
You do not need to believe that you will always receive necessary addenda & addendums from third party. Such addenda & addendums are very necessary to submit RFP response
Many times, you won’t receive necessary addenda & addendums on time, and government authority have very less time to submit response after they issue addenda.
Many times, Government Authority would like to contact you directly if you have registered with them directly. So, instead of directly submitting final RFP, it would be better to inform government authority that you will be submitting your response.
