Why founders hire a fractional CFO

Six situations account for nearly every engagement.

Model Built for the Raise

It produced a number for the deck
and has not
been opened since.

Bookkeeper + Accountant Hired

Neither tells you what to charge, which customers lose you money, or whether
the next hire
is affordable.

Collections Define Runway

Runway moves when collections slip —
a 30-day customer
becoming a 60-day customer can change the answer.

The Unprepared Questions

Investors ask why gross margin moved four hundred basis points in Q3, and whether the cause is mix or pricing.

Board Pack Misses Priorities

Twenty slides pulled from three systems, and the meeting still starts by debating the numbers.

Term Sheet Not Modeled

Liquidation preference, participation, option pools, and SAFE conversion determine what you actually keep in
the outcomes
that matter most.

When to hire a fractional CFO

The honest answer is not "as early as possible." It is when the cost of a wrong financial decision exceeds the cost of the engagement.

  1. You are a startup approaching or running a raise

    The most common trigger. A fractional CFO for startups earns their fee twice when the financial model is intact.

  2. You have crossed roughly $1m–$2m of revenue

    Below that, a competent founder with a good bookkeeper can usually hold it together. Above it, the number of interacting decisions — pricing, hiring, working capital, credit terms.

  3. You have taken on debt, or are about to

    Lenders underwrite cash flow rather than growth, and covenant compliance is a monthly discipline rather than an annual.

  4. Your board has started asking for things you cannot produce

    Cohort economics, contribution margin by segment, a real downside case. If the ask has moved beyond a P&L, the reporting function needs to move with it.

How the engagement works

Every engagement starts with the same diagnostic and then narrows to what you actually need.

  1. 1
    Weeks 1–2

    Diagnostic

    A full read of what exists: historical accounts, any current model, the reporting pack, the cash position and the commitments against it.

  2. 2
    Weeks 2–6

    Foundations

    Whatever the diagnostic identified as load-bearing. Usually a rebuilt three-statement model on real drivers, a 13-week cash flow forecast, and a reporting pack.

  3. 3
    Ongoing

    Operating Rhythm

    A monthly cycle: close review, variance against plan with the drivers explained, forecast update, and the two or three decisions that need a view this month.

  4. 4
    Event-driven

    Investor / Lender Readiness

    Diligence-ready financials, valuation work, scenario and sensitivity analysis, and preparing you for the questions before they are asked — so that you can answer them yourself with the numbers behind you.

What you get

Concrete deliverables, not advisory hours - models, forecasts, dashboards, and decision tools your team can actually use.

3-Statement Model

Built on drivers, reproducing your historicals before it forecasts anything, with a balance check.

13-Week Cash Flow

Updated weekly, showing the specific week cash gets tight under each scenario.

Monthly Board Pack

P&L, cash, KPIs, variance against plan with drivers explained, and a forward view.

Scenario Analysis

Base, upside, and downside scenarios that move the underlying drivers—collections, churn, and conversion.

Unit Economics Analysis

Contribution margin by segment, payback, and the
cohort view underneath them.

Transaction Readiness

Diligence-ready financials, valuation support, data-room financial content, and the question list you will be asked.

What a fractional CFO costs

Pricing is often opaque because three common engagement structures are compared as if they were equivalent.

Monthly Retainer

Ongoing finance leadership. Fixed monthly fee, defined scope.

Project Fee

Fixed price for a model, reporting rebuild, or raise-readiness package.

Day Rate

Best for diagnostics and focused, time-bound engagements.

Fractional CFO vs the alternatives

Four ways to get finance leadership.

1. Do it yourself

Cost
Your time
What you get
Full context, zero cost
Where it breaks
The founder-hours are the scarcest resource you have, and you find your errors when an investor does

2. Accountant

Cost
Low
What you get
Accurate records, filed on time
Where it breaks
Records the past. Does not forecast, price, or model a decision

3. Full-time CFO

Cost
High
What you get
Daily presence, builds and runs a team
Where it breaks
Salary plus equity before you have the scale to justify it. Hard to reverse if the fit is wrong

4. Fractional CFO

Cost
Mid
What you get
Senior judgement on the decisions that matter, investor-grade financials
Where it breaks
Not full-time. Not the right answer if you need finance team managed.

Frequently Asked Questions

A senior finance leader who works with your company part-time, on a retained or project basis, rather than as a full-time employee. You get CFO-level judgement on strategy, forecasting, capital and reporting, at a fraction of the cost and commitment of the hire. For a fuller explanation, see what a fractional CFO does.
Typically: financial modeling and forecasting, cash flow management, board and management reporting, unit economics, budgeting and variance analysis, and support through raises, debt facilities or transactions.
Most engagements are priced as a monthly retainer against a defined scope, with project fees for one-off deliverables. Cost is driven by company complexity, stage, the state of your historical accounts, and whether a financing event is live. See the pricing section above for ControlFi's structure.
When the cost of a wrong financial decision exceeds the cost of the engagement — commonly at $1m–$2m of revenue, eight to twelve weeks before a raise, when debt enters the picture, or when the board starts asking for analysis you cannot produce.
A controller owns the accounting function — close, controls, accuracy. A fractional CFO uses those outputs to make forward decisions on pricing, capital and allocation. If your numbers are late or wrong, hire the controller first.
Largely positioning. "Fractional" usually describes a part-time senior individual embedded with a startup or scale-up; "outsourced" usually describes a firm taking on the finance function for an established business. ControlFi offers both — see outsourced CFO services if you are an established company looking to hand over the function rather than add a part-time leader.
Yes. A fractional CFO does not replace bookkeeping or tax compliance and should not be doing either. They sit above both and depend on both being reliable.
Less relevant than it sounds. The work is scoped by deliverable and rhythm rather than logged hours — a model that takes forty hours and prevents a bad pricing decision is not better value at eighty.
That is one of the most common reasons to engage one, with one boundary worth stating plainly. The work is preparation: investor-grade financials, valuation work, scenario analysis and diligence readiness, informed by having seen these questions from the investor side. ControlFi does not introduce investors, solicit them, or negotiate terms on your behalf, and takes no fee contingent on a round closing. Engage before the round opens, not during it.
Ask to see a model they built. Ask what they would check first in yours. Ask what proportion of engagements they turn down and why. Anyone who cannot answer the third question is selling hours rather than judgement.
A diagnostic: a full read of your accounts, model, reporting and cash position, and a written assessment of what is sound, what is broken, and what it costs to fix. Including, where it applies, a recommendation not to proceed.
