Accurate estimates, profitable jobs
Built on 30+ years of real construction experience, Estimator Companion works the way builders and estimators actually operate. Estimating, quoting, and job management in one platform: intuitive, customisable, and designed to close the gap between pre-construction and site start.
Solution
A wrong estimate could be the most expensive mistake you make
Most estimators aren't missing steps because they're careless. They're missing them because their software doesn't guide them, their routines aren't standardised, and their quote never cleanly connects to the job. Estimator Companion closes that gap: guided takeoffs, customisable routines, and a single flow from model to quote to jobs to accounts with no double entry and no data left behind.
Guided takeoffs and build-type templates mean every step is accounted for and every quote goes out accurately. No nasty surprises when the job hits site.
Quote to job to accounts in a single login. No manual handoffs, no re-entry, no version confusion between your estimate and what actually gets built.
Fully customisable routines, takeoff pads, and purchase orders configured to your business. No workarounds. No remembering where things live.
Australian-based engineers who know the software and the industry. 99% of support queries are resolved within the first hour. No offshore call centres. No scripts.
