# 636.509 Can offerors revise their proposals as a result of discussions?

(a) Yes, you may request or allow proposal revisions to clarify and document understandings reached during discussions. At the conclusion of discussions, each offeror shall be given an opportunity to submit a final proposal revision.

(b) You must establish a common cut-off date only for receipt of final proposal revisions. Requests for final proposal revisions shall advise offerors that the final proposal revisions shall be in writing and that the contracting agency intends to make award without obtaining further revisions.
