Your R&D Tax
Claim, Sorted.

Lodged for you. Backed by us. Done the Right way.

Claiming R&D shouldn't cost you weeks, or a third of your return.

So we built Synnch differently. Real advisers prepare and lodge your claim, paired with tech that removes the recordkeeping grind. Spend less time proving what you’ve built, and more time building what's next.

Check Eligibility

More of what you're owed. Less of everything else.

Spend up to 70% Less.

Claim every dollar you're owed, and keep more of it. Work with us in a consulting + tech capacity, or tech only. Either way, you'll spend up to 70% less than you would with a traditional R&D consultant.

Win back your time.

Claiming at year's end can swallow 100+ hours you can't afford to waste. Working with Synnch brings that down to just one hour a month, spread across the year. Just 12 hours to do what used to take you weeks.

Lodge your claim faster.

Lodging the traditional consulting way can take 4–8 weeks. Because Synnch's tech has done the grunt work as you go, most of the claim is already built, so you lodge in days, not weeks.

Drop admin by 60%.

The grind of tracking R&D across the year, handled for you. Synnch streamlines your recordkeeping and claim preparation, cutting your R&D admin time by ~60%.

Keep your data & IP safe.

We’re ISO 27001 certified and Australian hosted – nothing is stored offshore. Your data and IP stays secure, and it's never used to train models outside of Synnch.

In the event of an audit, we will back you.

Lodge with Synnch and we’ll  help defend your claim, at no extra fee, if the ATO requests an audit (provided you’ve used Synnch to the required standard).

Discover how we’ll transform your whole R&D tax process.

First, we lessen your load – not just at claim time, but all year round.

01

Evidence, Captured.

Synnch pulls evidence from the tools you already use, so proof of your R&D builds as you work. ~1 hour a month is all it takes to oversee.

02

Evidence, Scored.

Every piece is scored for relevance and strength, building your audit-readiness in the background. See at a glance how your evidence stacks up.

03

Project Report, Drafted.

Synnch turns that evidence into your R&D project report: the technical write-up at the heart of every claim.

Then, when you're ready to claim? We handle that too.

04

We prepare, review and lodge.

As a registered tax agent, Synnch reviews your report and financials, prepares your claim, and lodges it on your behalf.

05

And we help defend your claim.

If the ATO ever queries a claim we've lodged on your behalf,  we will help defend it at no extra fee.

Advice and accountability
on tap.

Once a month Synnch members get on a call with Synnch founder & tax lawyer, Andrew Antonopoulos, and a room full of other founders.

What started as a product Q&A has become a power hour for real expertise, freely shared, on the things that actually keep founders up at night.

Questions and topics range from sharpening your evidence score to how R&D interacts with your capital raising, governance and overall tax position.

It’s also a great nudge for R&D accountability. Bring your monthly upkeep, work through it alongside people doing the same, and leave sorted. The “hour a month” isn’t a figure of speech, it’s literal.

Meet the Team

Don’t choose between
expertise and speed. Have both.

You don't want the slow, expensive consultant model. And you don't want software that offers no accountability when the ATO asks questions. Synnch combines the best of both: technology to streamline the work, and R&D advisors who care about your innovation as much as you do.

"Synnch gave us one structured place to pull together our technical activity records, evidence and cost inputs, without adding another layer of admin. Preparing our most recent claim was faster and better documented than doing it ourselves in spreadsheets, and it helped having a team who knew the R&D process well."

Your Questions, Answered.

Is Synnch a consulting firm or a tech platform?
chevron arrow

Both, and that's the point. We're a registered tax agent and R&D tax practice, so real experts prepare and lodge your claim. But we've also built our own proprietary technology platform that helps us, and you, do the work faster while keeping the rigour we stand behind. That's why we're happy to personally defend the claims we lodge. You get the expertise of a consultancy and the speed of technology we built ourselves, not one at the expense of the other.

Do I have to lodge with Synnch, or do I have options?
chevron arrow

You've got three ways to work with us. It's your call:

‍We lodge for you: We review your evidence, prepare your claim, and lodge on your behalf. Go this way and you're covered: if the ATO or Department of Industry, Science and Resources (DISR) queries it, this is where we help defend your claim.

‍Self-lodge: Use Synnch to capture and score your evidence all year, then export a claim-ready report that mirrors the AusIndustry submission portal, so around 60% of the work is already done. Finish the rest and lodge it yourself.

‍Bring your own consultant: Prefer to keep the consultant you have? Use Synnch to capture and score your evidence all year, then hand them a claim-ready report so they've got a head start on preparing and lodging.Whichever you choose, the hardest part, substantiating your R&D across the year with contemporaneous evidence, is already done.

Does working with Synnch mitigate my audit risk?
chevron arrow

Yes, absolutely. As a consulting firm and registered tax agent, reducing your risk is core to what we do, on two fronts.

First, your claim is built from real, timestamped records captured as the work happened, not a write-up reconstructed at year-end. Reconstruction is exactly what tends to draw ATO attention, so building contemporaneously is one of the best protections there is.

Second, you're not doing it alone. Every claim we lodge gets two layers of review: you check your records as you enter them, and our registered tax agent QAs the claim before it's submitted. If the ATO ever does query it, we help defend it, at no extra fee.

I want to keep working with my existing consultant. Does Synnch fit?
chevron arrow

Absolutely, plenty of members do exactly that. On a Synnch subscription, you get the tech to capture and score your evidence across the year, so your records stay clean and contemporaneous, while your own consultant handles the claim itself. The benefits in that case:

  • Invite your consultant onto the platform, free, so you're both working from the same source of truth
  • Spend far less time in meetings, chasing your team, and answering the same questions twice
  • Hand over a drafted claim report that cuts their prep work significantly
  • Bonus: your Synnch subscription is itself an eligible R&D expense, so you can claim it too

You keep the relationship you value, and make it work better.

Can't I just use ChatGPT to write my R&D evidence?
chevron arrow

You could, but it's a fast way to put your claim, and your IP, at risk.

Two problems. First, an R&D claim has to be built from contemporaneous records: evidence created as the work happened. A write-up generated after the fact, describing what probably happened, isn't contemporaneous. It's exactly the kind of reconstructed narrative that draws ATO scrutiny.

Second, sharing data with public AI tools runs the risk of being used as general knowledge or training material, meaning your proprietary R&D could be leaked.

Synnch's AI is a different thing entirely. It's not an open-source model, so your data never leaves to train ours or anyone else's. It is purpose-built for one thing: structuring your R&D the way a claim actually needs to hold up, drawing on 15+ years of R&D tax law built right into how it works.

The difference isn't speed. It's whether your claim holds up, and whether your IP stays yours.

Does the Synnch platform keep my data secure?
chevron arrow

Yes, and we treat it as seriously as you do. Synnch is ISO 27001 certified and built by security-conscious engineers to a rigorous standard. All your data is hosted in Australia, nothing is stored offshore. We don't use your data to train outside AI models, and we don't use it to train ours either. It stays yours, full stop.

You stay in control of what's uploaded: sensitive commercial detail is only ever needed if you choose to add it to strengthen your evidence score. Your proprietary work is often the most valuable thing you own, and with Synnch, it stays that way.
