One Platform for the Entire
Estimation Workflow

From building your master rate library to submitting a qualified tender — WinWin Estimator covers every step.

BOQ Manager

Build hierarchical Bills of Quantities with unlimited depth. Add items from your master library or create custom line items. Auto-generate sequential codes.

Learn more
Rate Analysis

Maintain a master library of Items of Work composed from your resource costs. British and Metric units, location-based pricing built in.

Learn more
Project Costing

Aggregate direct costs, add overhead line items, and set AIT and profit percentages. AIT is back-calculated from the grand total — just like real tenders.

Learn more
Tender Management

Track tender details, contractual conditions, pre-bid meetings with attendees, and competitor intelligence — all in one structured workspace.

Learn more
Site Visits

Record structured site visit findings — topography, access conditions, utilities, and risk factors — replacing paper notebooks with digital records.

Learn more
Team Access Control

Assign estimators to specific projects or BOQ sections. Five user scope types with 92 granular permissions ensure each person sees only their work.

From Library to Tender in 3 Steps

WinWin Estimator follows the exact workflow civil estimators already use — just digital, faster, and error-free.

1
Build Your Rate Library

Add resources (labour, materials, plant) with rates per location in British and Metric units. Define your master IOW tree with component compositions.

2
Build Your Project BOQ

Create a project and build its BOQ by selecting items from your rate library. Enter quantities — direct costs calculate instantly.

3
Generate Qualified Rate

Add overhead, set AIT and profit percentages. Distribute indirect costs proportionally to get the qualified rate per BOQ item — ready to submit.

Built for Bangladesh. Built Right.

  • British & Metric dual-unit support — Every project can use its own measurement system. Rates auto-convert — no manual recalculation.
  • AIT back-calculation (Bangladesh standard) — AIT is computed back from the grand total exactly as required by Bangladesh construction contracts.
  • Location-based rate schedules — Maintain different component rates per city or region. Dhaka rates vs Chittagong rates — automatically applied.
  • Hierarchical BOQ with unlimited depth — Build Section → Sub-section → Work Item trees exactly as your tender documents require.
  • Competitor intelligence built in — Track competitor companies, their quoted amounts, strengths, and weaknesses after each tender.
  • Scoped team access control — Assign an estimator only to their section — they cannot see other teams' pricing.
  • CSV exports for tender submission — Export cost summaries and qualified rate tables in seconds, ready for tender documents.

Yes. Each project is configured with either British or Metric measurement. Your master rate library stores rates in both systems. When you add a work item to a project, rates and quantities are automatically converted if the systems differ.

AIT (Advance Income Tax) is back-calculated from the grand total using the formula: AIT = (Grand Total × Rate%) / (1 − Rate%). This matches standard practice in Bangladesh construction contracts.

Yes. You can assign multiple estimators to a project. Administrators can also scope estimators to specific BOQ sections, so each person only sees their assigned work.
