Why this exists

Sound familiar?

You're making big decisions about hiring, pricing, raising, and borrowing off a bank balance and gut feel.

Investors, your board, or your bank are asking for reporting your current setup can't produce.

The “model” is a spreadsheet only one person understands, and nobody fully trusts.

Month-end takes weeks. By the time the numbers arrive, they're history.

A full-time CFO costs $250K+, and you don't need one full-time. You need the output.

That gap, too big for bookkeeping yet too early for a full-time CFO, is exactly what PrimeOne CFO covers.

An ongoing finance partner,

Monthly reporting refresh, dashboard maintenance, and asynchronous Q&A whenever questions come up.

Strategic

Everything in Growth, plus scenario and long-range planning, fundraise or loan readiness, and investor / lender materials.

Retainer scope and pricing are fixed in writing at the start: no hourly meters, no surprise invoices.

The founder

Work directly with the person who does the work.

PrimeOne CFO is a founder-led practice. When you engage us, you get me, not a junior analyst learning on your business.

I'm a triple-credentialed finance leader (CFA charterholder, CPA, and ACMA/CIMA) with more than a decade across FP&A leadership, financial modeling, and M&A due diligence performed for major private-equity investors. I've spent my career on the side of the table that scrutinizes numbers, so everything I build for you is constructed to hold up when an investor, board member, or lender pulls it apart.

  • Senior-led, always. The person who scopes your engagement does the thinking on it.
  • Built to survive scrutiny. Models and reporting made to withstand investor and lender diligence.
  • I build the infrastructure myself. Working models and live dashboards, not recommendations to go hire someone else.
  • Fast, fixed, transparent. A modern, AI-enabled production process means senior work in days, not weeks. That is why every price is fixed up front.

Who it's for

Built for startups and
growing businesses.

Funded startups

You've raised, or you're about to. New investors mean board reporting, a model that survives diligence, runway and scenario views. I build that machinery and keep it current, so you walk into every board meeting with answers instead of apologies.

Owner-led SMBs

No investors, just real stakes. Which products make money, whether you can afford the next hire, what the bank needs to see, where cash will be in six months. Same discipline, translated to your world: budgets, forecasts, margin analysis, and monthly reporting you'll actually read.

Preparing for a raise, loan, or sale

The moment outside money enters the picture, your numbers get judged. A fundraise model, a defensible valuation, and a clean data room are the difference between momentum and months of back-and-forth.

How it works

From first call to finished work.

  1. 1

    Free scoping call

    Thirty minutes to understand your situation and identify the right starting point. If I'm not the right fit, I'll say so.

    Written scope & fixed quote

    Deliverables, timeline, price, and what I need from you, agreed before anything starts.

  3. 3

    Build & checkpoint

    I work asynchronously around your schedule, with a mid-engagement checkpoint so nothing drifts.

  4. 4

    Delivery & walkthrough

    Finished, working assets, plus a session to hand them over and documentation your team can maintain.

  5. 5

    Ongoing support (optional)

    Continue on a retainer so your model, dashboard, and reporting stay current.

FAQ

Common questions.

Do I need a full-time CFO?

Probably not yet. That's the point. Most companies under roughly $30–50M in revenue need CFO-level output, not a CFO-level salary. When you genuinely outgrow fractional support, I'll tell you, and I'll help you set up the full-time hire for success.

I already have a bookkeeper / accountant. Is this the same thing?

No, and you should keep them. Bookkeeping records the past; tax keeps you compliant. I work on the forward-looking layer: models, forecasts, reporting, and the decisions they inform. I work alongside your existing bookkeeper or accountant.

How do we work together?

Remotely and asynchronously by default, with scheduled working sessions where the engagement includes them. You get responsive senior attention without adding meetings to your calendar.

What does “fixed price” actually mean?

The price in the written scope is the price on the invoice. If you ask for genuinely new scope, we agree on it in writing, with a price, before I build it.

Do you do taxes or audits?

No. PrimeOne CFO provides strategic finance services: modeling, planning, reporting, and analysis. I don't provide audit, tax, or legal services.
