ScaleWithCFO has hands-on experience in every aspect of a company’s finances. From bookkeeping and optimising financial systems to budgeting, forecasting, fundraising, exit planning, and due diligence, we’ve done it all. Whether it's high-level strategy or day-to-day financial operations, nothing gets overlooked - including planning for long-term growth.
We don’t just analyse numbers - we actively fix them.

This is a 30-minute video call on Zoom to explore your financial goals and challenges, and how ScaleWithCFO can address them. The call will include an introduction to our expertise, a discussion tailored to your needs, and a roadmap for the next steps.
It might look exhausting to have an hour call at the beginning but truth is that this is the most important area because you can't do any forecasts, financial planning, etc. if you don't understand what is the founder business and personal plans, learn about the business, competitors, their product or service etc.
After signing the engagement letter and completing AML checks, ScaleWithCFO spends around 30 days optimising your finances to SaaS/Tech standards, focusing on cost optimisation, KPI setup. Almost all the time the financials are super messy without founders knowing about it.
The next 60 days are for strategic planning and forecasting. The plan is customised to founder needs because every business is different. Maybe founders need to prioritise fundraising, need financial modelling, or have to implement new finance tools to make the finance system more efficient.
A fractional CFO is a senior financial leader who works with your business on a part-time retainer — typically 1 to 4 days per month. They handle financial modelling, cash flow forecasting, board reporting, budgeting, fundraising support, and exit preparation. Unlike a bookkeeper or accountant who focuses on historical records, a fractional CFO is forward-looking and strategic.
A fractional CFO in the UK typically costs between £1,500 and £7,000 per month on a fixed retainer, depending on your business stage and scope of work. For comparison, a full-time CFO costs £180,000–£250,000+ per year all-in. At ScaleWithCFO, we work on a fixed monthly retainer with no billable hours.
Most SaaS startups benefit from a fractional CFO once they reach £300K–£1M ARR, or when they begin preparing for a funding round. If your financial data is messy, you are spending too much founder time on finance, or investors are asking questions you cannot confidently answer — it is time.
An accountant prepares your year-end accounts, files tax returns, and ensures compliance — all backward-looking. A fractional CFO uses your financial data to drive decisions, plan growth, support fundraising, and manage risk — forward-looking. Most SaaS founders need both, but the CFO operates at the strategic layer.
Yes — ideally 3 to 6 months before you plan to raise. You need time to build an investor-ready financial model, clean up your data, prepare the data room, and rehearse investor questions. Doing this during active conversations with investors is stressful and often leads to lower valuations.
