Refer to the Buy Terms per each BPA/IDIQ to determine how long you need to hold pricing for. As well, if there is a Period of Performance indicated on the Buy, you may reference that as your time period. Otherwise, all bids placed on the Unison Marketplace marketplace are required to be honored for 30 days.
If a Seller is unsure of pricing offer period, they can submit a question on each individual Buy for the Buyer to review.
