Evaluate every bid faster — and defend every decision.
BidOS runs your tender end-to-end: publish the solicitation, receive sealed envelopes through the bidder portal, open them under committee authorization, and produce a sourced evaluation record your auditors can read line by line.
"We do the reading. You do the judging."
One inbox for every bid
Portal uploads, emailed offers, and hand-delivered envelopes land in the same auditable queue — no spreadsheets, no lost attachments.
Citations on every finding
Each AI observation points to the exact page and paragraph it came from. If the evidence is missing, the system says so.
Sealed until authorized
Financial envelopes stay closed until the technical stage is approved. AI output is held for human release before reaching the committee.
Audit trail by default
Every action — upload, opening, score, override — is written to an immutable log. Export the full record on demand.
What's inside
A complete chain of custody, from solicitation to opening register.
Solicitation workspace
Draft the tender, publish amendments, and answer clarifications without leaving the audit trail.
Bidder portal
Vendors sign in by account or magic link to download documents, upload sealed envelopes, and pull a signed PDF receipt.
Submission management
Live dashboard, bidder list, envelope status, external-import batches for email or paper bids, and grace-period flagging.
Authorized opening
Committee declarations, conflict-of-interest tracking, and an opening register PDF issued within ten minutes of authorization.
