Three tools, one platform

The three jobs
we do best.

Cost estimation, BoQ pricing, and tender adjudication. Three focused tools, all AI-driven and priced to your location and period.

Order of Magnitude Estimate

Cost Estimation

Upload drawings, assessment reports or cost documents. BidThinker extracts the works scope, estimates quantities, and builds up rates for your location and period.

Low / Likely / High → Excel

Pre-Tender Estimate

BoQ Pricing

Upload an unpriced Bill of Quantities, Excel, or scanned/digital PDF. AI prices every item with supply-and-install rates, wastage and OH&P for your market.

Priced Excel with live formulae

Financial Adjudication Report

Tender Adjudication

Upload up to 15 priced tenders. BidThinker checks arithmetic, flags omissions, benchmarks rates, and ranks submissions with a recommended tenderer and risk flags.

Client-ready PDF report
How It Works

Three tools.
One simple flow.

Whichever tool you reach for, it's the same three steps: upload, let the AI work, download a client-ready file. No training required.

Cost Estimation
01

Upload the documents

Drop in drawings, an assessment report or cost documents — scanned or digital PDF.

02

AI extracts & prices

The works scope is extracted, quantities estimated, and rates built up for your location and period.

03

Download the OME

A Low / Likely / High Order of Magnitude Estimate, exported to Excel.

BoQ Pricing
01

Upload the unpriced BoQ

Excel or scanned/digital PDF. Add the tender document for extra pricing context (optional).

02

AI builds the rates

Every item gets a supply-and-install rate with wastage and OH&P for your market and date.

03

Download the priced Excel

A fully priced BoQ with live formulae and a complete build-up to the tender total.

Tender Adjudication
01

Upload the tenders

Up to 15 priced submissions at once, in PDF or Excel, any format your contractors submit.

02

AI analyses everything

Arithmetic, omissions, market rates and compliance, every line item checked and benchmarked.

03

Download the report

A professional adjudication report with a recommended tenderer, risk flags and financial summary.

Features

Everything a QS needs.
Nothing they don't.

The capabilities behind all three tools, built from the ground up for construction and engineering procurement professionals.

AI Rate Build-Up

Supply-and-install rates with wastage and overheads & profit, built up by AI for the location and pricing period you choose. Powers both BoQ pricing and cost estimates.

Live-Formula Excel Export

Priced BoQs and estimates export to Excel with live =Qty×Rate formulae and a full build-up to the total. Change a rate in Excel and the whole sheet recalculates.

Scanned, Digital & Excel Intake

Upload tenders, unpriced BoQs or assessment reports as scanned PDFs (OCR), digital PDFs or Excel. BidThinker reads tables and line items accurately.

Arithmetic & Completeness

On adjudication, every rate × quantity is verified and omitted line items are flagged across submissions, calculation errors caught before they inflate the award.

Market Benchmarking

Rates are cross-referenced against market norms for the region and period. Outliers are flagged with percentage variance and context, on both priced tenders and your own pricing.

Comparison, Ranking & Reports

Compare up to 15 tenderers with AI BidScores and a recommended tenderer, or present a cost estimate as a Low/Likely/High range, in a client-ready report.

FAQ

Common questions.

Is my tender data secure and confidential?

Yes. All documents are encrypted in transit and at rest. Your tender data is never shared with other users or used to train AI models. Each company's data is fully isolated, only your team can access your projects. BidThinker complies with applicable data protection legislation.

What can BidThinker do?

BidThinker is three tools in one platform. Cost Estimation turns a structural/condition assessment report into an Order of Magnitude Estimate. BoQ Pricing prices an unpriced Bill of Quantities with AI-built rates for your location and period. Tender Adjudication checks, benchmarks and ranks priced tenders into a recommendation report.

What file formats does BidThinker support?

BidThinker supports PDF (digital and scanned, via OCR) and Excel. Upload tenders, unpriced BoQs or assessment reports as PDF or Excel; priced BoQs and cost estimates are exported to Excel with live formulae, and adjudications as a professional PDF report.

How many tenderers can I compare at once?

The Professional and Enterprise plans support up to 15 tenderer submissions per project. The Starter plan supports up to 5. All tenderers are analysed simultaneously and ranked using our BidScore algorithm.

Do I need technical training to use BidThinker?

No. BidThinker is designed for QS professionals, not IT teams. If you can upload a PDF and read a report, you can use BidThinker. We also provide onboarding support for all new accounts.

Can BidThinker replace my professional judgement as a QS?

No, and it's not designed to. BidThinker is a decision-support tool. It surfaces errors, flags anomalies, and benchmarks rates so you can make faster, better-informed recommendations. All final adjudication decisions remain the responsibility of the qualified QS.

What happens to my data if I cancel?

You retain read-only access to your projects and reports for 90 days after cancellation so you can export everything you need. After 90 days, all data is permanently deleted in accordance with our data retention policy.
