Every way your office needs to buy — in one platform
Reverse auctions, sealed bids, and best-value evaluations all run on the same audited, protest-ready foundation. Pick the method that fits the buy; keep one record, one vendor list, one workflow.
Reverse auction
A single line or lot put out to live competition. Qualified vendors bid the price down in real time until the clock closes, with anti-snipe protection.
Best when: one well-specified commodity or service where price is the deciding factor.
How reverse auctions work →Multi-line reverse auction
Every line item competes at once. Vendors can lead some lines and not others, and you award line-by-line or in aggregate to the lowest evaluated price.
Best when: a schedule of many items — supplies, parts, fuel — bought together.
How multi-line auctions work →Sealed electronic bid
Bids stay in a tamper-evident lockbox, hidden from everyone — including staff — until a scheduled public opening. The electronic equivalent of the sealed-envelope IFB.
Best when: statute or policy requires sealed bids opened at a set time.
How sealed bidding works →Unpriced technical proposal
Qualifications and approach, scored by a panel against weighted criteria — with peer scores kept private — for RFPs where the best proposal, not just the lowest price, wins.
Best when: professional services or complex work evaluated on merit.
How scored evaluation works →Whichever way you buy, the award holds up
The same integrity layer runs under all four methods — so switching approach never means switching systems or lowering your standard of documentation.
Tamper-evident audit trail
Every bid, addendum, and award decision timestamped to a record built for a protest or audit.
Binding addenda
Bidders must acknowledge each addendum; a new one flags active bids for one-click re-affirmation.
Not-debarred at award
SAM.gov exclusion screening plus insurance/bond/license status, checked before you record the award.
Statutory preferences
Local, MWBE, and veteran credits applied to the evaluated ranking — contract price stays the raw bid.
Qualified vendors
NAICS and commodity-code classification with targeted opportunity notices to matching vendors.
Public records, handled
Vendor-marked confidential material, staff-decided, released with a redaction log — never auto-exposed.
