What fractional CFO jobs involve
A fractional CFO does the work of a chief financial officer for a company that does not need or cannot afford one full time. The company has outgrown a bookkeeper and a part time accountant, but its questions are now strategic. How much runway is left? What does the next hire do to cash? Can we raise, and on what story?
You answer those questions. In a typical week, you review the books and the close, update the forecast, prepare reporting for the founder or board, and advise on pricing, hiring, and spend. You work with the controller or accountant instead of replacing them.
Companies that hire a fractional CFO are often seed to growth-stage software firms, service businesses, and consumer brands with revenue and a need to plan. Some need steady help. Others need a stretch of intense work before a raise or a sale.
What you can do in 5, 10 or 20 hours a week
Hours shape the scope. At 5 hours a week, you provide oversight, a monthly review of financials, a rolling forecast, and a call with the founder. This suits a small business with an existing accountant who needs a senior eye.
At 10 hours, you build and own the financial model and budget, run the monthly close review, prepare board or investor reports, and handle cash planning. That is the most common range for a standing role. You can read what it looks like in what a fractional CFO does in 10 hours a week.
At 15 to 20 hours, you take on fundraising support, due diligence, systems changes, or a finance team build. These bursts are usually temporary. Always agree the cap and the scope together, so the client knows what the hours buy.
Rates and a worked income example
Senior US fractional CFOs typically charge $175 to $300 an hour. Where you fall depends on your experience, the stage of the company, and how specialized you are, for example in fundraising or in a regulated industry. These are market ranges. They are not offers and not a promise of income.
The monthly math is hourly rate times weekly hours times 4.33. At $220 an hour for 10 hours a week, you earn $9,526 a month from one client. At $200 an hour for 6 hours a week, you earn about $5,196. You keep 100 percent of the agreed rate. The company pays the platform fee on top, which ranges from 5 to 12 percent depending on its plan.
Think about whether to charge by the hour or with a monthly retainer. On Side.work, billing follows approved hours in a weekly timesheet, so choose an hourly number that includes the time you spend on admin and prep.
Fractional CFO work compared with other routes
Finance leaders have several ways to work. Here is how fractional CFO jobs on Side.work compare with other common routes.
| Route | Hours control | Rate | Who finds clients | Contracts | Payment timing |
|---|---|---|---|---|---|
| Fractional CFO on Side.work | You set availability, contract sets weekly cap | You set it, you keep 100 percent | Matching and intros, plus applications | Platform contract with NDA and IP terms | Weekly timesheet, one invoice paid by the company |
| A second full-time CFO job | Fixed, long hours | Salary and equity | You or a search firm | Employment agreement | Payroll |
| Freelance bidding sites | Project based | Often pushed lower by bids | You, through proposals | Varies | Per site rules |
| Consulting through an agency | Agency decides | Agency keeps a margin | The agency | Subcontract | After the agency is paid |
If you want to serve several companies and keep your rate, the first row is the closest. If you want to build an equity stake in one company, a full-time role is better.
How to present your profile to growing companies
Companies search for a finance leader with the right stage and problem. Say which. "Fractional CFO for B2B software, seed to Series B, forecasting and investor reporting" is easy to match. "Experienced finance professional" is not.
List the tools and methods you use in general terms, such as three-statement models, cash forecasts, revenue recognition, and month-end review. Add whether you work with the existing accountant. Mention if you have helped teams prepare for a raise or an audit, without naming clients you cannot name.
Verification matters. Side.work checks your work email domain, your LinkedIn profile, live portfolio links, and your payout identity. In the first call, expect to be asked what you would look at in the first week. A good answer names the bank balance, the last three months of financials, the pipeline, and the next big expense.

Employment, conflicts and ownership of your work
If you hold a full-time finance job, read your agreement before taking a client. Look for moonlighting limits, conflict of interest language, and invention assignment. A company that competes with your employer, or that is a supplier or customer, is a risk. Side.work asks you to confirm that your side work does not conflict with your employment terms. This is general information, not legal advice. Ask an employment lawyer if a clause is unclear.
With several clients, avoid direct competitors unless both agree in writing. Keep each set of books and models private. Each contract on the platform includes a default NDA and IP assignment, so you know who owns the models and reports you build. Read contracts for fractional work for more.
You are an independent contractor, so you handle your own taxes. Check what licenses or professional rules apply in your state.
What clients expect in the first 90 days
Companies hire a fractional CFO to reduce uncertainty. In the first 30 days they expect you to understand the numbers, find the biggest gaps, and give them a clear picture of cash and runway. In the next 30, they expect a working forecast and a monthly reporting rhythm. By day 90, they expect decisions to be easier because the data is trusted.
Do not promise more than the hours allow. If the books are in poor shape, say so and agree a plan, even if the first weeks are spent on cleanup with the controller or accountant. Clear scope is covered in how to scope a part time senior role.
Timesheets and payouts for fractional CFOs
Finance work can be hard to see, so keep clear notes. In your weekly timesheet, group hours by task, for example forecast update, close review, board prep, and advisory call. The company approves the timesheet, then pays a single invoice for approved hours plus the platform fee.
Payouts go to a connected bank account after our payment processor checks your identity. You do not chase invoices. If a company ends the engagement, the notice period in the contract sets how long you continue to work and bill.
Agree upfront what happens if the scope grows. A cap of 8 hours that keeps getting hit is a signal to renegotiate, not to work for free.
