About Multi Line Item Bids
Multi Line Item Reverse Auction
Multi-line reverse auctions that drive price down — and hold up to a protest.
Put every line item out to live competition at once. Qualified vendors bid each line down in real time, you award line-by-line or in aggregate to the lowest evaluated price, and every move lands on a tamper-evident record.
Illustrative example — figures are for demonstration only.
One event, every line, real competition
A multi-line reverse auction turns a multi-item solicitation into a single live event. Vendors see the current low on each line and bid to beat it — so the market sets your price, line by line, in the open.
✓ Line-by-line bidding
Every line item runs its own competition simultaneously. Vendors can lead some lines and not others — you capture the best price on each.
✓ Live or sealed
Run it as an open descending auction with a real-time low, or as a sealed multi-line event opened at a scheduled time — your rules, per solicitation.
✓ Anti-snipe auto-extend
A bid in the final seconds extends the clock, so no line is won by the clock instead of the price. The extension window is yours to set.
✓ Award your way
Award each line to its low bidder, or award the whole schedule in aggregate — whichever your solicitation specifies. The system ranks candidates for you.
✓ Statutory preferences, on the record
Local, MWBE, and veteran preferences are applied to the evaluated ranking automatically — while the contract price stays the vendor's actual bid. The math is stored, not done in a spreadsheet.
✓ Only qualified vendors
Classify vendors by NAICS and commodity codes and notify the ones who match. Bidding stays open to the field you invited.
✓ Addenda that bind
Post an addendum mid-solicitation and every active bid is flagged for one-click re-affirmation — no one bids against superseded terms.
✓ Not-debarred at award
The winning vendor is checked against SAM.gov exclusions, and insurance/bond/license status is surfaced, before you record the award.
✓ Anomaly advisories
Math errors and unit-price outliers are flagged for staff review at tabulation — advisory only, never an automatic disqualification.
How a multi-line reverse auction runs
Set the line schedule
Create the solicitation, add each line item with unit, quantity, and an optional engineer's estimate, and set the bid window.
Reach qualified vendors
Matched vendors are notified by classification; the opportunity posts to your public portal.
Vendors bid it down
During the window vendors bid each line, seeing the current low and their rank, with anti-snipe protection on the close.
Award to lowest evaluated
Review raw and evaluated prices side by side and award by line or in aggregate, with the not-debarred and compliance checks applied.
Keep the file defensible
Bids, addenda, preferences, and the award decision are captured to a tamper-evident audit trail and a post-award contract record.
The savings are the headline. The record is the reason.
Transparent competition
A live, rules-based descending auction is easy to explain to a council and hard to challenge — the price was set by the market, on the clock, in view of every bidder.
A protest-ready file
Every bid, addendum acknowledgment, preference calculation, and award decision is timestamped to a tamper-evident log — the documentation a bid protest or audit asks for, produced automatically.
Compliance built into the award
SAM.gov exclusion screening and insurance/bond/license status are part of recording the award, not a separate paper folder done after the fact.
Public records, handled
Vendors flag confidential material at submission; staff decide each claim; the system produces a release package that withholds only what was approved — with a redaction log.
