Engineer-led. Melbourne-built.

Your MVP, live in under two weeks. Up to 43.5% backif you're R&D eligible.

We turn your idea into working software, built and documented so eligible companies can claim the R&D Tax Incentive. AusIndustry and the ATO decide eligibility, your accountant or registered R&D advisor confirms the claim, and we build the evidence trail that supports it. Fixed quote. You own the code and the IP.

The R&D Tax Incentive, in plain English

Australia refunds a big slice of genuine R&D spend. A properly run software build can be exactly that.

What it is

Companies with aggregated turnover under $20 million can claim a 43.5% refundable tax offset on eligible R&D expenditure. The work must be experimental: outcomes unknown in advance, conducted to generate new knowledge. Routine builds on known frameworks do not qualify, which is why the scoping matters.

What we do

We structure the build around the real technical unknowns and document them as we go: hypotheses, experiments, results, git history. When your advisor prepares the claim, the evidence already exists.

Who decides

AusIndustry and the ATO decide eligibility, and your accountant or registered R&D advisor confirms and lodges the claim. We work alongside them; we never promise you a claim.

This page is general information about the R&D Tax Incentive, not tax advice. Talk to your accountant or a registered R&D advisor about your circumstances.

Where we stop, and your advisor starts

The R&D Tax Incentive is tightly regulated, and the penalties for getting it wrong are real. Here is exactly how we work so your claim stays defensible.

  • We are engineers, not tax agents. We build the software and the technical evidence. We do not assess your eligibility, calculate your refund, or lodge your claim. Your registered R&D advisor or accountant does that, and we hand them everything they need.

  • We work with your R&D advisor. Already have one? We slot in alongside them. Need one? We can introduce you to a registered R&D tax adviser. The eligibility call is always theirs to make.

  • We never take a cut of your refund. You pay a fixed price for the software, full stop. We never charge a percentage of your R&D offset. Contingent fees are how the incentive gets abused, and we do not go near it.

  • You own everything. Full code, IP and results are yours from day one, in your repositories, built onshore in Australia. Owning the results and bearing the project risk are also part of what makes your claim valid.

What you get

A working product, not a deck

Real software your first customers can log into: web app, API, integrations, the lot. Scoped tight so it ships in under two weeks.

An R&D evidence trail

Architecture decision records, spike tickets, experiment logs and test plans, produced as we build, the way AusIndustry's software guide asks for it. Contemporaneous records your advisor can actually defend, not a reconstruction at tax time.

Fixed quote, no hourly billing

One number after the discovery call. You know the cost before we write a line of code.

Your code, your IP, onshore

Everything in your repositories on Australian-resident cloud or your own servers. Overseas development is generally ineligible for the R&D incentive without an advance finding, so building onshore in Melbourne keeps your claim options open.

Idea to live product in five steps

  1. Discovery call

    We map the idea, the riskiest technical unknowns and the smallest product worth shipping. Free, and you leave with a scope either way.

  2. Fixed-scope quote

    One price, one timeline, and a build plan structured around the experimental work that may qualify as R&D.

  3. Build in the open

    Daily commits you can watch. Technical uncertainty and experiments get documented as we go, not reconstructed at tax time.

  4. Live in under two weeks

    Your MVP in front of real users on your infrastructure. We hand over the code, the docs and the evidence trail.

  5. Iterate or automate

    Next rounds of product, or plug in our voice agents, automation and content engine to run the business side.
