What does it Mean?: Inconsistencies do not exist

This is usually on the cover/signing sheet to be submitted with proposals:

The undersigned agrees that enclosed submission is in response to the above-referenced solicitation document, including any addenda. Through this submission we agree to all of the terms and conditions of the solicitation document and agree that any inconsistent provisions in our proposal will be as if not written and do not exist.

So, as a buyer, we put this in the RFP/RFQ/ITQ/EOI/RFPQ to avoid vendor proposals coming in with a 'counter-proposal' ie terms that conflict with the terms of our document and/or additional terms that we cannot accept, etc. Usually a counter-proposal would be disqualified, but that requires legal advice prior to evaluation, so to save some time, some legal advisors have drafted this language to put into our RFPs so we can ignore the 'counter-proposal' terms and continue in our evaluation as if they weren't written. HOWEVER, we will still need to seek legal advice as we cannot be 100% sure this language will override language written in a proposal (we can't foresee what a vendor's lawyer may write).

For the vendors, if you submit your usual private sector template with your own sales contract, it generally will be ignored and by signing this RFP document with this language, the intent is that you understand you will be agreeing to the buying organization's terms and conditions. Without this language in the RFP, you *might* just be disqualified if your sales contract contradicts what is contained in the RFP...

Again, seek your own legal advice...
