Most firms bring in a fractional CFO about a year after they need one. The signs were there the whole time. They just looked like ordinary problems: a tight month, a tense comp meeting, a budget that never quite made it across the finish line.
Here’s the short answer. A law firm should hire a fractional CFO when its financial decisions have outgrown the time and training of the partners making them. A fractional COO comes in when the same is true of how the firm operates.
The rest of this post is how to tell when you’ve reached that point, which role you need first, and when it’s better to wait.
When should a law firm hire a fractional CFO?
When the firm needs senior financial judgment more often than the partners can supply it. In practice, that shows up as one of six moments. One on its own is worth watching. Two or more at the same time is a strong signal it’s time.
- There’s no budget, or one nobody uses. The firm is making next year’s decisions without a plan to measure them against.
- Revenue is up and profit isn’t. The work is coming in, but the margin isn’t following it. (I covered where that profit usually goes in Law Firm Profitability Models.)
- Cash is tight in a good year. Collections lag, receivables age, and payroll depends on a client paying on time.
- The firm has hit a ceiling. Growth has stalled and nobody can point to why.
- Partners are doing the books. The people who should be leading the firm are reconciling accounts at night.
- A big decision is coming. A lateral hire, a merger, a new office, a new comp model, or the departure of the person who ran the finances.
From the finance side: the quickest test I know is a simple question. Which practice area made the most money last year? If the answer takes a week, or comes back as a guess, the firm has outgrown how it runs its numbers.
Is budget season a good time to start?
It’s the best time. A fractional CFO who starts in the fall helps build next year’s budget instead of inheriting one that was already set.
The budget is where the hard decisions live: headcount, rates, partner comp, and which practice areas get investment. Starting now means the decisions get made with someone at the table who has seen them play out before. Starting in February means living with a plan nobody tested.

Do we need a fractional CFO or a fractional COO?
Look at the questions keeping you up. If they’re about money, start with a CFO. If they’re about how the work gets done, start with a COO.
Start with a fractional CFO when the questions sound like these:
- Where did the profit go?
- Can we afford this hire?
- Are our rates right?
- Why is cash tight when we’re busy?
- How should we pay the partners?
Start with a fractional COO when they sound like these:
- Why does every decision still land on my desk?
- Who owns this process?
- Why didn’t the new system fix anything?
- Why does every new hire create new problems?
Most growing firms start with the CFO, because the numbers usually show where operations are breaking. I’ve held both seats inside law firms, and the two jobs overlap more than people expect. Some firms combine them under one engagement.

When is a firm not ready yet?
When the partners can’t yet say what kind of firm they want to become. A CFO can build the plan to get there, but can’t choose the destination for you.
A few other signs it’s better to wait:
- You’re shopping on price alone. The cheapest option rarely includes the judgment you’re actually hiring for.
- You want the roadmap before anyone has seen your numbers. A plan written before the firm is understood is a template, not a plan.
- The partners aren’t ready to act. Better numbers only help if someone is willing to make a decision with them.
None of these are permanent. Most firms that aren’t ready today are ready a year later, once the direction is settled.
How do you know it’s time for your firm?
Run four quick checks with your partners. If most of the answers make you uncomfortable, it’s time to talk to someone.
- Count the moments. Go back through the six signs above. How many describe your firm right now?
- Review your last three big decisions. Were they made with numbers everyone trusted, or with instinct and a spreadsheet someone built the night before?
- Time your reports. How many days after month-end do the partners see the numbers? If it’s weeks, decisions are running on old information.
- Name the owner. Who at the firm is responsible for the business side? If the honest answer is “everyone” or “the managing partner, after hours,” nobody really owns it.
Where 3sixty fits
I’ve sat in the CFO, COO, and CEO seats inside law firms, and today I work as a fractional CFO for growing firms. Every engagement starts the same way: I learn the firm and where the partners want it to go before I recommend anything.
The fee is one flat monthly amount, set once we understand what the firm needs. Our own accounting team keeps the books law-firm-ready, so the reports land on time and the CFO work starts from numbers you can trust. When the bigger issue is operations, fractional COO support works the same way.
If two or more of those six moments sound familiar, book a 30-minute consult. We’ll talk about your firm and where it’s headed. No pitch deck, and no pricing until we understand the firm.
