Who it is for
Queensland painting contractors quoting weekly who are losing bids on presentation and speed, not on price. You do the walk-through and the pricing; we turn every quote into a proposal that looks like you invested in it.
See the client proposal pilot
The accepted-job pilot adds a hosted, branded proposal beside the free estimator. It is priced at $0 monthly, with a capped fee only after a verified acceptance.
This is the proposal format being tested. Scroll the sample:
The full 21-page product sample. Hosted acceptance is enabled pilot by pilot.
Queensland pilot, local rules
Hosted acceptance, contract delivery and deposit handling require local legal and payment checks. Kastrion is validating that path with Queensland businesses before wider release.
Built from real jobs
The engine is a cell-for-cell port of an estimating system a working Australian painting business quotes with every day, reconciled against real invoiced jobs to the cent. It runs on your device, offline, on site.

Frequently asked questions
What does painting estimating software do?
It turns measurements into a priced quote: rooms in square metres, coats and prep, with GST. Kastrion also keeps a free job record and PDF export on your device.
How is Kastrion different from PaintScout or a DIY tool?
Kastrion is painting-specific, Australian and built from real invoiced jobs. The estimator works offline and uses your rates. Hosted client proposals are opening separately through a Queensland pilot.
Is it free?
The estimating calculator, saved job records and PDF export are free. The Queensland proposal pilot has no subscription, and the first three accepted jobs are fee-free. See pricing for the exact caps.
Is it available outside Queensland?
The free tools work anywhere in Australia. Hosted proposals and accepted-job pricing are opening through a controlled Queensland pilot first.
