BUILDXACT ESTIMATING SERVICE

We estimate your Buildxact jobs in Wunderbuild for you.

Feasibility estimates qualify jobs fast. Detailed estimates price them accurately. We build both in Wunderbuild and deliver them importable to Buildxact. Pick the one that matches where the job is.

Feasibility Estimate

For early conversations, when a client asks "roughly how much?" and you need a real answer without committing weeks of work. We build a full itemised feasibility in Wunderbuild in 3-5 business days using our feasibility framework across every trade, then deliver it importable to your Buildxact account, so the number holds up and lives where you work.

When to choose it:
  • Client hasn't signed yet, you need a price to win the deal
  • Plans are preliminary or still evolving
  • Budget conversation before scope is locked in
  • Multiple projects competing for your quoting time

Detailed Estimate

For jobs you're ready to win and price properly. We build a full, contract-ready estimate in Wunderbuild, trade by trade with every allowance itemised, then hand it back as an importable Excel file that drops straight into your Buildxact account. You get estimating-team accuracy without leaving the platform you know.

When to choose it:
  • Client is committed and you need a fixed-price quote
  • Plans and specs are finalised
  • You want every cost line contract-ready
  • You're too busy on site to spend 20 to 40 hours estimating

WHEN YOU CAN'T STOP TO ESTIMATE

Your job is building. Not estimating.

A full residential estimate takes 20 to 40 hours of focused work. Most builders don't have that. Phones ring, sites need visits, subbies need answers, and estimates get squeezed into evenings and weekends where quality suffers. Our team builds your estimate inside Wunderbuild, gives you access to review it, and delivers an importable Excel file you drop straight into Buildxact. You get a client-ready quote without leaving the platform you know.

Built for Buildxact
We estimate in Wunderbuild, where we're fastest and most accurate, then deliver an Excel file that imports cleanly into your Buildxact account.
Estimator Accuracy
Built by qualified estimators using 10+ years of Campbells pricing data. Every job checked twice before it lands in your inbox.
