No more BCC'd emails
Documents, addenda, and bids scattered across inboxes. No version control, no proof of receipt, no audit trail.
No more unsealed bids
The sealed envelope process is all but gone in the digital age. No way to prove bids were held unopened until closing, a real probity risk.
No more tedious evaluation
Scoring spreadsheets built from scratch each time. No consistency, no second opinion, and nothing defensible to hand the client.
No more “trust me” answers
When the board, the AGM, or a losing bidder asks how you made the call, TenderBox hands them a document — a timestamped record of every action taken.
Everything a tender process needs
Sealed bids
Bids are locked until closing time
Tenderers submit via a private portal link. Bid details are hidden from everyone (including you), until the tender closes. The sealed envelope process, restored for the digital age.
Formal opening
A formal tender opening, every time
When the tender closes, your client automatically receives a formal opening summary listing every submission received and its price, just like the envelope-opening process of old.
Q&A management
Questions broadcast to all tenderers
Tenderers ask questions through their portal. You answer once, and every invitee receives the response simultaneously. Maintain fairness and a complete addenda record.
Weighted evaluation
Consistent scoring across every tender
Define your evaluation criteria and weightings. Score each submission against them and generate a formal evaluation report to include in your recommendation.
Audit trail
Every action logged and timestamped
An audit log records every event. See invitations sent, bids received, questions asked, bids opened. All with timestamps and attribution. A complete, exportable probity record. If your practice is ISO 9001 accredited, it maps directly to your quality management obligations.
AI Co-evaluator
A second committee member on every bid
Claude optionally reads each bid and scores it against your weighted criteria as an independent evaluator. It then produces an executive summary across all bids. See who came out ahead, how price compares to quality, and what to follow up before awarding. You stay in control of the final recommendation.
No accounts for tenderers
Bidders get a link, not a login
Tenderers access their portal via a private link in their invitation email. No account creation, no passwords, no friction. They download the documents, ask questions, and submit their bid.
AI Co-evaluator
A second committee member on every tender
Claude reads each bid submission and scores it against your weighted criteria. Independently, consistently, and without the fatigue that comes with manual review.
AI scores sit alongside your own, clearly attributed. You stay in control of the final recommendation. The AI makes you sharper, and provides defensible and impartial analysis to show the client.
