Most growing companies reach a point where the numbers need a senior owner. The books close, but nobody is translating them into a plan, a fundraising story or a cash strategy. A full-time CFO is often more than the business can justify, and that is where a shared CFO comes in.
This guide explains what a shared CFO is, what shared CFO services include, how the time is split across clients, how the role compares to fractional, interim and full-time CFOs, and what to expect in the first months of working together.
A shared CFO is an experienced chief financial officer who works part-time for several companies at once, usually on a monthly retainer. Shared CFO services cover forecasting, cash management, reporting, budgeting and fundraising support. In the U.S., the same role is usually called a fractional, part-time or outsourced CFO. It fits companies that need CFO-level judgment before they need a full-time executive.
What Is a Shared CFO?
A shared CFO is a senior finance executive who serves several companies at the same time, giving each one a defined share of their time each month. The company gets CFO-level strategy, planning and reporting without hiring a full-time executive. The term is common internationally; in the U.S., the same model is usually called a fractional CFO.
The labels overlap. Shared, fractional, part-time, virtual and outsourced CFO all describe an experienced finance leader who is not a full-time employee. If you are comparing providers, our guide to what a fractional CFO is covers the same role under its most common U.S. name.
What Shared CFO Services Include
Shared CFO services cover the strategic side of finance: forecasting, cash management, budgeting, management and board reporting, and support for fundraising or major decisions. The shared CFO relies on accurate monthly books from an accounting team and turns them into plans, analysis and recommendations for leadership.
| Area | What a shared CFO typically does |
|---|---|
| Forecasting and planning | Builds and maintains the financial model, annual budget and rolling forecast |
| Cash management | Tracks cash and runway, plans for working capital needs and flags shortfalls early |
| Reporting | Sets the KPIs leadership reviews and delivers monthly management reports |
| Board and investors | Prepares board materials and investor updates backed by detailed projections |
| Fundraising and financing | Prepares the model, data room and story for equity or debt conversations |
| Finance team oversight | Reviews the accounting team’s close and sets priorities for controls and systems |
How a Shared CFO Splits Time Across Companies
A shared CFO works on a set schedule, often a monthly retainer that covers a number of hours or days, plus agreed availability for urgent questions. The time is not spread evenly across the month: it concentrates around your close, board meetings, planning season and decisions such as a fundraise or a major hire.
The arrangement works best when expectations are written down: which meetings the CFO attends, how quickly they respond between meetings, which deliverables arrive each month and who on your team prepares the data. Because the CFO serves other companies, confidentiality terms should be part of the agreement from the start.
| What shared does not mean: your financial information is not shared with other clients, and you are not sharing a finance team. You are sharing one senior person’s calendar, while your data, reports and decisions stay specific to your company. |
Shared CFO vs. Fractional, Interim and Full-Time CFO
A shared CFO and a fractional CFO are the same model under different names: part-time, ongoing CFO leadership. An interim CFO is a temporary full-time leader who fills a gap, and a full-time CFO is a permanent executive. The right choice depends on how much CFO time your decisions need and for how long.
| Factor | Shared / fractional CFO | Interim CFO | Full-time CFO |
|---|---|---|---|
| Time commitment | Part-time, ongoing | Full-time, temporary | Full-time, permanent |
| Typical trigger | Need for CFO judgment before a full-time hire | Departure, transition or a short, intense project | Scale and complexity that fill the role every day |
| Employment | Contractor or provider | Contractor or provider | Employee and officer |
| Best fit | Growing companies and startups | Companies between CFOs | Larger or later-stage companies |

What to Expect in the First 90 Days
Expect the first 90 days with a shared CFO to move from diagnosis to a working planning rhythm. The CFO reviews your financials and systems, builds or rebuilds the model, sets a reporting cadence and then starts using the numbers to guide the decisions in front of you.
- Review historical financials, the chart of accounts, contracts and the current close process.
- Agree on the priorities for the engagement with the founder or CEO.
- Build or rebuild the financial model, budget and cash forecast.
- Set a monthly reporting package and the meeting calendar with leadership and the board.
- Start using the forecast to guide hiring, pricing, spending and financing decisions.
How to Choose a Shared CFO
Choose a shared CFO based on experience with companies at your stage and in your industry, availability that matches your calendar, and how well they work with your accounting team. Ask who covers when they are unavailable and what you receive each month. Our guide on how to choose a fractional CFO lists the questions to ask before you sign.

Frequently Asked Questions
Is a shared CFO the same as a fractional CFO?
Yes, in practice. Both describe an experienced CFO who works part-time for several companies under an ongoing arrangement. “Shared CFO” is more common outside the U.S., while U.S. companies usually search for fractional, part-time or outsourced CFO services. The scope, pricing model and deliverables are the same.
How much do shared CFO services cost?
Cost depends on the hours or days included each month, the complexity of your finances, the deliverables you need, such as board reporting or fundraising support, and the CFO’s experience. Providers usually scope a monthly retainer after reviewing your financials, which is the best way to compare it with a full-time hire.
How many companies does a shared CFO work with?
It depends on the CFO and the size of each engagement. What matters for your company is the time and availability written into your agreement: how many hours or days you receive, how quickly the CFO responds and who covers when they are unavailable.
When should a company hire a shared CFO?
Consider a shared CFO when leadership needs forecasts, cash planning or board reporting that nobody on the team owns, when you are preparing to raise capital, or when growth makes spending decisions riskier. Most companies make this move before they can justify a full-time CFO.
Can a shared CFO help with fundraising?
Yes. A shared CFO can build the financial model, prepare the data room, shape the financial story for investors or lenders and support due diligence. Leadership still owns the relationships and decisions, while the CFO makes sure the numbers hold up to scrutiny.
