How it works

Three steps to a
client-ready budget.

PrelimPro guides you through the estimate — handling the structure and calculations while you apply your professional judgement.

01

Upload your plans

Drop in your PDF drawings — concept sketches, DA documents, or anything in between. PrelimPro reads what's there and asks you to fill in what isn't.

PDF · Any stage
02

Review & build the estimate

The tool extracts key quantities and pre-fills a line-by-line cost plan using current Australian rates. You review every assumption, adjust specs, and apply your own knowledge where it matters.

Guided · Editable
03

Share with confidence

Export a clean, professional PDF bearing your details. A preliminary cost plan that clearly communicates the budget range — and sets the right expectations from day one.

Who it's for

Built for the early
budget conversation.

Three different professionals. One shared problem: needing a credible number before the project is fully defined.

01

Developer & Owner

Property developer / owner-builder

Test feasibility before committing to design fees. Know whether your project stacks up financially before you're locked in to anything.

"I can't justify drawings without knowing the cost — and I can't get a cost without drawings."
02

Builder & Contractor

Small–medium builder

Qualify leads fast and set expectations at the first meeting. Stop spending weekends on detailed quotes for projects that were never going ahead.

"I've lost too many evenings pricing jobs that weren't real."
03

Architect & Designer

Architect / interior designer

Reality-check your concept before you're deep in documentation. Avoid the painful DD-stage redesign when a client discovers the actual cost for the first time.

"We redesigned the whole scheme at DD because no one checked the budget early."
