If I submit a proposal for a reverse auction, can I refine any of the details before the auction closes?

You will be able to revise your total price, item prices, assumptions, and question responses at any time during the reverse auction.

You may change total price by selecting Revise Proposal->Revise Total Price. Item prices, assumptions, and question responses may be changed by selecting Revise Proposal->Revise Proposal.

Any change in ranking as a result of firms revising their pricing will be shown to all firms in real time. The client will allow auction bidders to view either their competitive ranking or ranking + price.  You will see which ranking view applies by visiting the Comparison view when drafting a proposal.
