About
Fractional CFO and Interim CFO support for $5m–$50m organisations that need
clearer cashflow, stronger reporting and tighter financial control
Diamond Business Advisory provides experienced Fractional CFO, Interim CFO and financial governance support for organisations that need clearer numbers, stronger reporting and more confident decisions.
Led by Eve Diamond, the firm works with CEOs, founders, executive teams and boards, who need senior financial leadership without the cost or complexity of appointing a full-time CFO.
Work directly with Eve Diamond
Eve Diamond is a CPA, Board Director and senior finance leader with more than 30 years’ experience across CFO, Board Director, Treasurer and advisory roles.
Her work sits at the point where financial clarity, governance and commercial decision-making meet. She helps organisations understand what their numbers are saying, what needs attention, and what decisions should be made next.
Eve’s background includes CFO leadership, board reporting, audit and risk oversight, governance remediation, financial modelling, cashflow management, business transformation and finance function improvement.
Eve is particularly experienced in not-for-profits, healthcare, technology, founder-led businesses and regulated environments where boards and executives need practical, decision-ready financial insight.
When you work with Diamond Business Advisory, you work directly with Eve, our advisory relationships are never handed to a junior consultant.
Clients receive senior financial leadership, clear judgement and practical support grounded in real operating environments.
Who we work with
Diamond Business Advisory works with organisations that have outgrown basic financial reporting and need more strategic financial leadership.
This often includes not-for-profits, charities, purpose-led organisations, founder-led businesses, growing private enterprises and organisations with active boards or governance committees.
The common thread is not size alone. It is complexity. Clients usually come to Diamond Business Advisory when they need clearer cashflow visibility, better board reporting, stronger governance, more reliable forecasting, or a finance function that can properly support growth and decision-making.
We work especially well with:
• CEOs who need clearer financial insight before making decisions
• Boards that need stronger reporting, oversight and governance confidence
• Not-for-profits managing grants, funding complexity and sustainability pressures
• Founders who need senior finance support without a full-time CFO appointment
• Organisations moving from reactive bookkeeping to strategic financial leadership
A senior-led model, supported by a trusted specialist team
Diamond Business Advisory is intentionally senior-led. Eve leads the advisory relationship, sets the direction and remains closely involved in the work that shapes financial reporting, governance and decision-making.
Where additional support is needed, Diamond Business Advisory works with a carefully selected team across bookkeeping, accounting support, tax coordination, payroll, and reporting preparation.
This model gives clients access to senior CFO judgement while also providing practical delivery support behind the scenes. It means the work can move beyond advice into implementation, without requiring the client to build a full internal finance team before they are ready.
You receive senior financial leadership from Eve, supported by experienced finance specialists where the work requires additional capacity. The model is designed to be practical, scalable and commercially sensible.
What we help strengthen
Most clients do not come to Diamond Business Advisory because one report is late or one forecast needs updating. They come because the finance function is no longer giving the CEO, founder or board the clarity they need.
The work may begin with cashflow, reporting, forecasting, governance or finance team support. Over time, it often becomes a broader improvement program that strengthens decision-making, accountability and confidence.
Financial Clarity
Clearer reporting, stronger management accounts and better visibility over performance, cashflow and risk.
CFO leadership
Fractional CFO and Interim CFO support for organisations that need senior financial leadership without a full-time appointment.
Board confidence
Board reporting, governance support, audit readiness and financial oversight that helps directors make better decisions.
Finance function improvement
Practical support across bookkeeping, payroll, tax coordination, internal controls and reporting processes.
Not-for-profit support
CFO support for charities, associations and purpose-led organisations managing funding, grants, governance and sustainability.
Why the model works
Clients choose Diamond Business Advisory when they need more than compliance and more than generic advice.
The value sits in combining senior CFO experience with practical implementation support. That combination helps organisations move from unclear reports, reactive decisions and financial noise to stronger insight, better control and more confident leadership.
The work is direct, commercially grounded and designed around what the organisation actually needs next.
Support can take different forms
Depending on what the organisation needs, the work may take the form of ongoing Fractional CFO support, short-term Interim CFO support, not-for-profit CFO services, board and governance support, or managed finance support.
The right starting point depends on the level of complexity, urgency and internal finance capability already in place.
If your organisation needs clearer reporting, stronger financial leadership or better support around board-level decision-making, the best place to start is a focused conversation.
Diamond Business Advisory can help you understand what level of support is right for your organisation now, and what should happen next.
