Finance and back-office automation · Australian mid-market

Your ledgers stay.The finance workaround them runs itself.

We build custom AI systems for finance and back-office work. They sit on top of the Xero, MYOB or ERP you already run. AI does the daily work. A named person approves anything that touches money or risk.

In 60 minutes we map one repeated task and whether a build pays for itself. You meet the founders who would build it, and the conversation is on us.

Your systems stay in place Scope and price in writing The code is yours Every figure from tested code

In production: at a 200-person food manufacturer in Ukraine the system now does an economist’s 2-3 hours of daily calculations. See the case →

Sales are 6.8% ahead of last year, and the gap is widening: September alone beat last September by $59k.

Week 9 is the pinch: GST and a big stock order land together and cash dips under your $250k buffer. Eight weeks' notice is enough to fix it.

Profit is up $126k. Selling more did the heavy lifting. Dearer stock, wages and freight took $169k of it back.

Free cash after equipment spend is $426k for the year. The three dips are the months new equipment was paid for, each one planned ahead.

Liquidity has climbed seven months in a row: $1.84 of short-term assets now stands behind every $1 owed, above the 1.5× target.

$31k is over 90 days, spread over three customers. Chase those first. The $412k current book is paying on time.

We connect ledgers and ERPs with payroll, stock and spreadsheets. Running something else? If it has an API, an export or a database, we work with it.

The finance work that repeats every week is the work we take off the desk.

Typing, checking, matching and chasing run on their own. A named person approves anything that touches money or risk.

01

Month-end close still takes weeks?

Reconciliations, accruals and checks run on schedule. Exceptions wait for your review.

02

Invoices still typed by hand?

They are read, checked and matched to your ERP. 99% of lines coded automatically. A person signs off before anything is paid.

03

Numbers once a month? Once a week?

One client’s economist rebuilt them by hand, 2-3 hours every day. Now the whole picture is on the screen every morning.

04

Overdue invoices piling up?

Reminders go out on a +7 / +14 / +21-day ladder, in your own voice. Only the stuck accounts reach a person.

05

Still waiting on the figure you need?

It waits for you now. Ready the moment you ask, at any hour, from the latest figures in your ledgers. Or ask it out loud →

06

Want reporting shaped around how you steer?

You get the figures and breakdowns you steer by, set out in your own words.

If the work is repeated on a computer, it may be worth automating.

Our newest build · a virtual CFO

A CFO you can ask out loud. Every figure comes from tested code.

We have built a virtual CFO over a group of company ledgers. The director types or speaks a question. The answer is read aloud first, then drawn on the screen. It comes from the group’s own books, every company at once.

  • Code writes every number.The AI chooses which calculation to run and puts the result into words. Every figure comes from code we test.
  • What it says and what the screen shows are one calculation.The spoken figure and the chart always match, because both come from that one result.
  • Every figure opens to where it came from.Its basis in one sentence, and the transactions it was added up from. This is the part a CFO checks.

Your process
Bends to fit the product.
What you pay
A subscription, per user or per document, for as long as you use it.
What you own
A licence.

Your process
Built around it, by people who have run a month-end themselves.

Sergii and Alex Diatchenko, TwinMind, Brisbane

Who we are

Twin brothers. Both trades.

We are twin brothers in Brisbane. Each of us is both at once. We are finance professionals who have carried a real ledger, and engineers who have built production systems.

Each of us has spent more than twenty years doing those two jobs at the same time. Alex built the accounting system a packaging group runs in twenty of its plants. The system Sergii built for an international voice business ran the whole company, with a hundred people working inside it every day.

Agents write the code under our design and standards. We review every line. We work as architects. Twenty years of building these systems ourselves is what makes that solid.

Audit trail

Every step leaves a trail an auditor can follow.

Approved

Anything touching money or risk is approved by a named person.

Scoped

Scope, acceptance criteria and price in writing before the work starts.

Asked at almost every first meeting.

Have another one? Ask it in the conversation. The answer comes from the people who would build it.

How much does finance automation cost?

You see the number before anything is built. The first conversation is on us. The opportunity audit is a fixed A$2,000, credited in full against your first build. It hands you a costed plan you approve before any build begins. Integrations start from A$500, and every build is a fixed price agreed up front.

Xero and MYOB have their own AI now. Why build anything?

Use it where it fits: it does good work inside its own ledger. We connect Xero, MYOB and your ERP around your process. Every figure comes from tested calculations.

I’ve heard AI makes mistakes. Why trust it with the books?

The models we build on learned from a vast body of text. Our agents also work from your own company data: the full ledger history, your documents and your rules. The mistakes you hear about come from one agent working alone, from a small slice of knowledge, deciding everything by itself. Asked that way, roughly 20-30% of finance answers come back wrong.

We split every decision across several agents. Each one answers for its own part: one reads the documents, one runs the calculation, one checks the result against the records. An answer is released once they agree, and the figure itself always comes from tested code. With the agents cross-checking, that 20-30% falls to 0.0%.

Can the AI get a number wrong?

Code produces every number. The AI decides which calculation to run and puts the result into words. The figure itself comes from code we test, and every figure opens to the records behind it. Anything that moves money is approved by a named person.

What do you automate?

Finance and back-office work, end to end. Accounts payable: invoices read, coded and matched. Reconciliation: bank, intercompany and clearing accounts. Month-end close, consolidation and management reporting. Cash flow forecasting, free cash, working capital, liquidity and debtor days. Product costing, margin and stock visibility. Document work: forms, contracts and obligations. Each one is a custom AI system on your existing systems and workflows, with a live ERP dashboard on top.

Do I have to change my accounting system or ERP?

Your systems stay. We automate the work around the tools you already run. We read from them and write back to them. They keep running as they do today.

Is my data safe with AI?

Client systems are hosted in Australia. Human approval stays in place for money, risk and legal steps, and every action is logged for audit. We design around Australian privacy obligations from the start.

How long does it take?

A focused first system is usually scoped in days and built over 1 to 2 weeks. We confirm the timing before the build starts.

Who keeps it running after the handover?

You do, with us beside you if you choose. The code, the configuration and every record sit in your repository, and the care plan keeps the system tuned. From the first hour to the handover you work with the founders who own the outcome.

Australia, 2026
