What it is
EstimateOne Tender Management brings commercial construction tender work into one place for builders to invite subcontractors, track responses, and manage supply-chain decisions. The Project Wizard and Document Matrix organize uploaded drawings into trade-specific packages. The Addenda Wizard notifies subcontractors about updates, while automated transmittals and audit trails help teams follow document versions. Live coverage, response rates, and pricing trends are shown together. AI quote analysis can compare quotes side by side, flag scope or price discrepancies, and draft clarification lists. SharePoint integration supports project document syncing, and Procore integration supports digital tender handover. Builder Core costs 6000.00 AUD per year (+GST, billed annually); Builder Business costs 9000.00 AUD per year (+ GST, billed annually). Enterprise pricing is on request. The partner API currently exposes Speci-finder matched project results for supplier users; other API surfaces are in development. Integrations are pull-based, with no webhooks or push events, and E1 has no published SDK. Builder onboarding is guided by Customer Success and usually takes around two weeks.
