Built by civil engineers, for civil engineers. We understand the estimation workflow because we lived it.
For years, civil engineering estimators in Bangladesh worked with Excel spreadsheets that broke on formula updates, email chains that scattered tender documents, and notebooks that captured site visit observations that nobody could find later.
WinWin Estimator was built to change that. We digitised the entire pre-contract estimation workflow — from building a master rate library to generating a qualified tender rate — in a single, connected platform designed specifically for how Bangladesh contractors actually work.
AIT back-calculation, dual British/Metric unit support, BOQ hierarchical trees, competitor intelligence — these aren't generic features. They're the exact requirements of every civil tender in Bangladesh.
Every calculation in WinWin Estimator is exact — AIT back-calculation, unit conversion, cost distribution. No rounding shortcuts.
Your estimation data is sensitive competitive intelligence. It is never shared, never analysed for third parties, and always encrypted.
A BOQ that used to take 3 days in Excel should take 3 hours. WinWin Estimator is engineered to be fast at every step.
Estimation is a team sport. WinWin's scoped access model ensures every person on a team sees exactly what they need — nothing more.
WinWin Estimator is a product of win4win.biz, a technology company based in Bangladesh focused on building practical software solutions for the construction and engineering industry.
We build tools that civil engineers actually want to use — not generic project management platforms with a "construction module" bolted on. Every feature in WinWin Estimator exists because a real Bangladesh contractor asked for it.
