What a fractional CFO is

A fractional CFO is an experienced chief financial officer who works for your company part of the time, but on a lasting basis. This fits when your numbers get more complex but a full-time role does not pay off yet.

An interim CFO fills a gap for a few months; a fractional CFO works with you on fixed days each month over a longer period. The model is also called an outsourced CFO or CFO as a service.

When a fractional CFO pays off

When Your Company Needs a Fractional CFO

Usually when founders spend more time on spreadsheets than with customers. Typical triggers are an upcoming funding round, new investors with reporting duties or a runway that is getting shorter. An experienced outside view also helps when the budget and the hiring plan no longer fit together.

Before a Funding Round

You need a financial model, a data room and answers to investor questions. When the process starts, your cash should last another 12 to 18 months.

After a Funding Round

Investors expect regular reports with metrics that show the real business, not just reach and clicks.

When the Numbers Get Complex

Several products, markets or entities make planning and control harder than a founder can manage on the side.

The difference in practice

Without Finance Leadership or with a Fractional CFO

Many growth companies do not fail because of the idea, but because of missing financial control. This is what the difference looks like.

Without finance leadership
Typical consequences
Blind spots: Decisions are made on gut feeling because current figures are missing.
Unit economics: Nobody knows the cost of a new customer, so growth uses more cash than planned.
Weak reports: Investors receive reports that raise more questions than they answer.
Late warnings: Cash shortfalls only show up once they have arrived.
Result: short runway, time pressure in the next round and a weaker negotiating position.

Cash planning: A liquidity plan that shows how long your cash lasts and is kept up to date.
Control: A regular budget versus actuals review, so you see where you deviate from plan and why.
Scenarios: A three-case financial model to test hires and budgets before you commit.
Reporting: Investor reports that explain clearly what the figures mean.
Result: a planned runway, figures that hold up in due diligence and a stronger negotiating position.
The Offer

What Our Fractional CFO Does

We take on the finance leadership tasks your team does not cover. Bookkeeping and annual accounts stay with your tax adviser, and we build on them. You see the results in our client portal, Roemer Capital OS: budget versus actuals, benchmarks and a financial health check, integrated planning of profit and loss, balance sheet and cash, and reports explained in plain language.

Planning and Financial Model

Integrated planning of profit and loss, balance sheet and cash over at least three years, in three cases. We show what new hires or higher marketing spend mean for runway and valuation.

Controlling and Reporting

Ongoing budget versus actuals, budgeting, metrics such as LTV/CAC and CAC payback, and reports for management, the board and investors.

Funding and Investors

Preparing the next round, the data room and answers to investor questions. When a round is due, we can also run the capital raising process.

The collaboration

How We Work Together

We start with a review of your figures, systems and goals. Then we agree how many days per month you need and which reports arrive when. We work with your team and your tax adviser and keep adjusting the plan.

Growth Scenarios and Forecasts

Answers Instead of Theory

A good financial model answers real questions. What happens if the conversion rate drops? How long does the cash last if the sales team doubles? We give you the answers before you decide. Our models are built to hold up in due diligence.

Fees

A Fixed, Predictable Fee

You pay a fixed monthly fee based on the number of days agreed per month. We do not bill by the hour. If we also run your funding round, the CFO work is part of that mandate's fixed monthly amount, plus a success fee set out in a fee agreement that is signed before the investment agreement. We publish no price list.

What is a fractional CFO?

A fractional CFO is an experienced chief financial officer who works for your company part-time and without a permanent contract. They handle planning, controlling, investor reporting and the preparation of funding rounds. You get the experience of a finance leader without filling a full-time role.

How much does a fractional CFO from Roemer Capital cost?

You pay a fixed monthly fee based on the number of days agreed per month. We do not bill by the hour and do not publish a price list. If we also run your funding round, the CFO work is part of that mandate's fixed monthly amount, plus a success fee set out in a fee agreement that is signed before the investment agreement.

Who is a fractional CFO for?

For technology companies with a product in the market and running revenue, typically between Series A and Series C. It makes sense when the numbers get more complex but a full-time role does not pay off yet.

When does a startup need a CFO?

At the latest when a funding round is coming up or investors expect regular reports. Another sign: nobody on the team can say for sure how long the cash will last. When a round starts, runway should be 12 to 18 months, and someone has to plan it.

What is the difference between a fractional CFO and an interim CFO?

A fractional CFO works on a lasting basis with fixed days each month; an interim CFO fills a gap for a few months, usually full-time. Interim assignments often bridge an open position. A fractional CFO builds planning and reporting and stays with you over a longer period.

What is the difference between a fractional CFO and a controller?

A controller prepares reports and checks figures; a CFO helps decide what the figures mean for strategy and funding. The fractional CFO builds the plan, talks to investors and prepares rounds. A controller on your team can support that work.

When is a fractional CFO better than a full-time CFO?

As long as the work does not fill a full role. You pay for the days you need instead of a full salary. When the need grows, the fractional CFO prepares the handover to your own finance lead.

What does a fractional CFO do day to day?

Cash planning, budget versus actuals, budgets, metrics and reports for management and investors. On top of that come the three-case financial model and the preparation of the next round, including the data room. You see the results at any time in our client portal, Roemer Capital OS.

How does working with Roemer Capital work?

After a free first call we look at your figures, systems and goals. The offer sets out how many days per month you need and which reports arrive when. We then work with your team and your tax adviser.

Does a fractional CFO replace my tax adviser or bookkeeping?

No. Bookkeeping, annual accounts and tax stay with your tax adviser, because we are not a tax advisory firm. We build on their figures and turn them into planning, control and investor reporting.

What are the benefits of a fractional CFO?

You always know how long your cash lasts and where you deviate from plan. You test decisions on hires and budgets before you make them. And you go into the next round with figures that hold up in due diligence.
