The Current State

Once bids are opened,
the process leaves your control.

Tendering is a fiduciary process. Yet the moment returns are unsealed, most firms hand the numbers to outsiders, wait months for answers, and hope the record holds up. Four structural weaknesses, each one a cost, a delay, or a governance exposure.

01

Third parties

Opened bids are passed to external consultants and suppliers for analysis. Their existing relationships with the bidders are invisible to you, and once the numbers leave the building you cannot control where they travel.

02

Audit exposure

Analysing bids in-house raises its own questions: no separation of duties, no independent record of who saw what, and when. Either route leaves the award open to challenge.

03

Time

After a three to four month tender period, analysis, negotiation and resubmission add another fourteen weeks before a recommendation is signed. Programme cost accrues the whole time.

04

Cost

Rate outliers and missing items go undetected in spreadsheets. Value is left on the table in every negotiation, and no one can say how much.

How It Works

Seven steps, one ledger.
Invitation to award.

Every step is timestamped, role-controlled, and recorded. The process reads the way it runs: in order.

01 Create Tender Project details, packages, budget, and timeline, structured from the start. No template wrangling. Under 10 min
02 Select Contractors Invite from your pre-qualified contractor database, graded by discipline, region, and tier. Minutes
03 Sealed Submissions Bids are sealed on receipt at database level. No user or role can view a return before opening. Bid period
04 Controlled Opening Time-locked opening requiring two named approvers. Minutes of opening generated automatically. At deadline
05 Commercial Analysis Every BOQ parsed, aligned, and compared across returns, with rate outliers flagged for review. Under 1 hour
06 Negotiation Schedules Per-contractor schedules identifying where each return sits against the field, item by item. Same day
07 Award Pack Minutes, analysis, schedules, and the full audit bundle. Exported in one action, ready for the board. One click
Time Reclaimed

Fourteen weeks after opening.
Or on opening day.

Analysis runs in the background the moment bids unseal. Full tender analysis and negotiation schedules are ready before the committee leaves the room, and resubmission comparisons re-run in minutes, not weeks.

Governance

A tender process you can
defend, line by line.

Tenderbox is built so that probity is a property of the system, not a promise from the people running it.

Sealed Bids

Sealed at database level

Submissions are encrypted and locked the moment they arrive. Not restricted by permissions: structurally unreadable until the opening event. There is no administrator override.

Controlled Opening

Dual-approval opening

Opening a tender requires two named approvers acting after the deadline: the digital equivalent of two keyholders at the box. The event, its approvers, and its exact time are recorded automatically.

Audit Trail

Append-only, hash-chained record

Invitations, submissions, addenda, openings, downloads: every action is written to an append-only log, each entry chained to the last. Amendments are additions; nothing is ever rewritten.

Separation of Duties

Roles that cannot collide

The person who creates a tender, the people who approve its opening, and the people who analyse returns hold distinct roles with distinct permissions, enforced by the platform, not by policy documents.

Evidence on Demand

The full record, exportable

Any tender's complete audit bundle exports as a single package: every event, hash, approver, and timestamp. If an award is questioned, the answer takes minutes, not a forensic exercise.

Built on real procurement governance

Your process. Not a startup's
reinvention of it.

Tenderbox follows the procurement lifecycle your auditors already recognise, with an e-approval gate at every step a signature used to sit.

01
Tender strategy

Route, criteria and bidder list approved and frozen before issue.

02
Pre-qualification

Structured PQQ, licences and insurances tracked to expiry.

03
Invitation

Lean ITT pack generated and issued to the approved list.

04
Queries & addenda

Answers issued to all tenderers; acknowledgement logged automatically.

05
Sealed submission

Bids locked at database level with an instant automated receipt.

06
Opening committee

Quorum of named approvers; no individual can unseal alone.

07
Technical evaluation

Weighted scoring approved before commercial envelopes unseal.

08
Commercial analysis

Every bill compared like-for-like, outliers flagged, same day.

09
Negotiation

Identical packs, identical deadlines, sealed responses.

10
Award

Recommendation with full chronology, e-approved, evidence bundle attached.

Fast-track single-envelope or conventional two-envelope. Works packages or consultancy services. The governance holds either way.

Commercial Analysis

Your QS team, augmented.

The analysis a strong QS team would produce over a fortnight, drafted in under an hour. Every figure traceable, every flag reviewable, every judgement still theirs.

  • A

    BOQ parsing and alignment

    Multi-sheet bills parsed as submitted, real-world formatting included, then aligned item-for-item across all returns. No re-entry, no transcription errors.

  • B

    Outlier detection

    Rates that sit outside the field are flagged with their spread and context, so review effort goes where the money is.

  • C

    Negotiation schedules

    Per-contractor schedules showing exactly which items to challenge and by how much: the working document for the clarification meeting.

  • D

    Award-ready exports

    Comparison tables, schedules, and minutes in Excel and PDF, formatted for the recommendation report, not for rework.

Your Data

Your data stays yours.

Every tender you run builds your own private rate library: structured, searchable, and visible only to your team. It is never shared, pooled, or sold. Over time it becomes the benchmark you price your next cost plan against.

Private by design

Your rates, your tenders, your records: accessible to your organisation and no one else.

Built from your own tenders

Each completed tender adds cleanly structured rates to your library automatically. No separate data entry.

Your benchmark, compounding

Historic rates by trade, region, and package: the most accurate reference your estimators will ever have.

Security

Built to institutional expectations.

Short answers to the questions your IT and audit teams will ask first.

Hosting
Cloud infrastructure selected with regional data governance in mind. Data residency requirements are addressed per client engagement.
Encryption
All data encrypted in transit (TLS 1.2+) and at rest (AES-256). Sealed submissions carry an additional encryption layer released only at the opening event.
Access Control
Role-based access with least-privilege defaults, enforced separation of duties, and multi-factor authentication for approver roles.
Audit
Append-only, hash-chained event log covering every action on every tender. Fully exportable for internal audit or external review.
Assurance
Security programme built on an ISO 27001 alignment roadmap, with independent penetration testing planned each release cycle.
