Why an outsourced CFO

Senior financial leadership, sized to where you actually are

You need CFO-level insight to grow — but not a six-figure full-time salary. A fractional CFO from System Six gives you the strategy, forecasting, and clarity of a seasoned executive, on flexible terms.

Cash flow forecasting you can trust

Know what your bank balance will look like weeks and months out. We build rolling forecasts so you can hire, invest, and plan with confidence instead of guesswork.

Custom reporting that drives decisions

Board-ready reports and dashboards built around your KPIs — not generic templates. Understand margins, runway, and unit economics at a glance.

Project & client profitability tracking

For agencies, consulting firms, and service businesses: see which projects, clients, and services actually make money — and which quietly drain it.

A dedicated team, not a chatbot

Work directly with experienced US-based finance professionals and CPAs who learn your business — real partners you can call, not an AI assistant.

The System Six difference

The most complete outsourced finance team for your business

Other services bolt an advisor onto their software. We lead with people — 40+ US-based professionals averaging 10+ years of experience — backed by the systems to keep everything accurate.

People-first, not software-first

You get a senior CFO and advisory team who know your name and your numbers — the kind of judgment automated bookkeeping platforms can’t replicate.

Fits into what you already have

Keep your current bookkeeper or bring it all to us. Our CFO advisory works alongside your existing setup and integrates with your tools and databases.

Full-service finance, one partner

CFO advisory, bookkeeping, payroll, tax, bill pay, and controllership under one roof — so nothing falls through the cracks as you scale.

Built for service & software businesses

Deep experience with agencies, consulting firms, and tech companies from $1M to $20M+ in revenue — we speak your business model.

90-day ROI plan

Rapid onboarding and a clear plan to deliver measurable value in your first 90 days — audit-ready, compliant, and accurate books throughout.

Transparent, flexible pricing

Fixed weekly pricing from $400 with no long-term contracts. Scale services up or down as your needs change — no surprises.

How it works

From first call to CFO-level clarity in weeks

Getting started is simple — and it begins with a free consultation, not a contract.

Questions

Outsourced CFO services, explained

What does an outsourced (fractional) CFO actually do?
A fractional CFO provides senior financial leadership on a part-time or as-needed basis. That includes cash flow forecasting, budgeting, custom management reporting, profitability analysis, financial strategy, and guidance on major decisions like hiring, pricing, and fundraising — without the cost of a full-time executive.
How is this different from bookkeeping software or an AI platform?
Software records what already happened. Our CFO advisory team interprets it, forecasts what’s ahead, and helps you decide what to do next. You work with real, experienced US-based finance professionals — not a dashboard or chatbot.
Can you work with my current bookkeeper or accountant?
Absolutely. Our CFO advisory is designed to work alongside your existing bookkeeping. If you’d prefer a single full-service partner, we also offer bookkeeping, payroll, tax, and bill pay — but that’s your choice, not a requirement.
What does an outsourced CFO cost?
We use fixed, transparent pricing that scales with your needs — with services starting from $400 per week and no long-term contracts. Your exact plan depends on your revenue, complexity, and goals, which we’ll define together during your free consultation.
What types of businesses do you work with?
We specialize in service businesses, consulting firms, agencies, and tech/software companies — typically in the $1M to $20M+ revenue range, including multi-location providers. We’ve served 300+ clients and manage $200M+ across them.
How quickly can we get started?
We’re known for rapid onboarding. After your consultation and scope agreement, we connect to your systems and get your forecasting and reporting foundation in place quickly — with a 90-day plan to deliver measurable ROI.
