Outsourced Finance Solution

Embedded finance for growing business.

Kirbyko is an embedded finance solution for businesses, combining bookkeeping, finance operations, and virtual CFO support into one integrated financial system.

Clarity in Numbers

Structure through Systems

Confidence for Growth

escape reactive finance

Most businesses don’t have a revenue problem.

They have a financial visibility problem.

When financial reporting lags behind business growth, decisions become reactive, cash flow gets harder to predict, and founders end up carrying too much operational knowledge in their head.

Kirbyko combines bookkeeping, finance operations, and virtual CFO support into an embedded finance function for growing founder-led businesses.

Instead of chasing numbers across spreadsheets, inboxes, and disconnected reports, you gain structured visibility, financial ownership, and decision-ready reporting.

our Financial infrastructure

Kirbyko acts as the embedded finance function for growing businesses and organisations that have outgrown reactive finance.

We combine bookkeeping, finance operations, and virtual CFO support into one integrated financial system - bringing structure, visibility, and financial ownership to organisations navigating increasing complexity, growth, and operational pressure.

Each layer of our model plays a distinct role, from financial accuracy and reporting through to operational oversight and strategic decision-making.The result is a finance function designed for growth, not just compliance.

Bookkeeping Foundations

Financial accuracy before financial strategy.

Structured bookkeeping, reconciliations, payroll, and reporting designed to create reliable financial visibility.

This layer creates the operational foundation businesses and organisations need before forecasting, strategy, and growth decisions can happen confidently.

Outsourced Finance Function

A financial operations engine integrated into your business.

We manage the day-to-day financial operations that growing organisations often struggle to coordinate internally.

This includes reporting workflows, financial oversight, cash flow visibility, and full-scope operational finance management.

Advisory &
Virtual CFO

Strategic financial direction grounded in operational reality.

Forecasting, budgeting, pricing analysis, cash flow planning, and financial support designed to help you make confident decisions with clearer financial visibility.

This is practical financial direction connected directly to how the organisation actually operates.

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.”
