Yes has enabled us to price multiple projects at the same time and not have to delay tender submissions.The ability it offers our company to focus on project delivery as opposed to project quantification.

Our Approach to Cost Estimation
At Big Estimate, cost estimation isn’t just about quantity takeoffs, it’s about reducing friction, increasing win rates, and helping NZ contractors run profitable projects.
Trade-Centric Thinking
Each estimate is scoped by trade, so roofing reports look nothing like tiling or insulation ones. This keeps your quotes clean and your subs on the same page.
NZ Code & Builder Format Compliance
We align every output to what local builders and suppliers expect, right down to fixings, fasteners, and wastage buffers.
Data-Led Accuracy + Human Oversight
We use software like Planswift, but every project is reviewed by a senior estimator before delivery. So you’re getting both precision and accountability.
Lean Yet Scalable Approach
No bloated reports. No generic BoQs. Just actionable numbers you can use today to quote, negotiate, or order.
We Act Like an Extended Estimation Desk
Not a third-party agency. Not a marketplace. We work like your own back-office team fast, accountable, and always reachable.
