Senior commercial leadership without a $300k salary
The fractional CFO difference
A fractional CFO, often called a Virtual CFO, is a senior finance leader who embeds in your business a few days a month. You get the same strategic muscle as a full-time CFO: cash flow forecasting, growth modelling, profit strategy and boardroom-ready reporting, without the $300,000-plus salary.

Whether you are planning a hire, reviewing margins or preparing lender information, the advice is grounded in your business's numbers.
