CUSTOM SYSTEMS SETUP

A system built around how you actually run your business.

Off-the-shelf software doesn't fit how every builder runs their business. A sole trader doing custom renos needs a fundamentally different system to a team of 15 doing commercial fit-outs.

ESTIMATING SERVICE

Hand over the plans. We hand back the numbers.

Some builders want to stay hands-on with estimating. Others want it off their plate entirely. If you'd rather be on-site than behind a spreadsheet, our full project estimating service takes the work off you completely.

ADD-ONS & SUPPORT

Training, support, and the tools that keep everything sharp.

The three core services cover most builders' needs, but the work behind the work is just as important. Whether you want to bring estimating in-house, keep your system running clean over time, or get expert eyes on what's already in place, our add-ons round out the offering.

Estimator Training (from $1,200/session)

Half-day or full-day training sessions for your team.

Ongoing Support Service ($35/month)

Technical support for Custom Systems Setup and Custom Template clients.

Systems Audit & Advisory ($900)

Standalone deep dive on your existing setup, with software comparisons and recommendations.
