Outsourced Finance Solution

financial clarity and control to grow confidently.

Kirbyko unifies your numbers, systems, and financial strategy to give you a clear view of where your business stands and where it can go.

Clarity in Numbers

Structure through Systems

Confidence for Growth

Feel confident and in control

Smarter Numbers,
Better Business

When you’re focused on running your business, it’s easy for the financial side to fall behind. Before long, you're reacting instead of planning - and major decisions are made with gut-feel, not reliable numbers.

Bring structure to your numbers, and you’ll have direction to your decisions.

At Kirbyko, we operate as an extension of your team to run your finance function, end-to-end. From managing systems and workflows, to reporting and day-to-day financial operations, we ensure your finances are managed with clarity and consistency.

Our Services

Whether you’re building strong foundations or preparing for your next phase of growth, our services are designed to give you clarity, structure, and consistent financial support - all through one trusted partner.

We bring together bookkeeping, financial operations, and strategic advisory to create a complete outsourced finance function that scales with your business.

Bookkeeping Foundations

For accurate, compliant, reliable numbers.

Accurate records, tidy Xero, and clean data give your business a solid financial foundation. Having numbers that actually mean something is where confidence starts.

Outsourced Finance Function

A structured, organised, and fully managed financial engine

Systems, workflows, AP/AR, invoicing, reporting, and financial admin handled end-to-end to give you organisation, consistency, and the capacity of an in-house finance team without the overhead.

Advisory

Insight that guides smarter decisions

Forecasting, pricing, budgeting, cash flow planning, and strategic direction that transform your financial data into clear next steps. A forward-looking view rooted in strategy so you can plan with confidence, not guesswork.

Meet Jack Rathmell

Your financial partner in growth

“I’m Jack, founder of Kirbyko and I’ll be working with you directly.

I started Kirbyko after years of working with small business owners who were drowning in confusion, disconnected from their numbers, and left to figure it out alone. That’s not how it should be.

At Kirbyko I take a hands-on, proactive approach, so you’re never left chasing updates or wondering what’s going on behind the scenes. You can expect straight-up advice, honest conversations, and no unnecessary complexity.

My goal is to bring structure, clarity and calm to your finances so you can make smarter decisions and grow with confidence.”
