What Does a Fractional CFO Actually Do in 90 Days?

What Does a Fractional CFO Actually Do in 90 Days?

Posted on |

In the first 90 days, a fractional CFO should answer three questions: what’s true in your numbers right now, what happens next, and what should change. That’s the whole job at the start. Month one makes the books current and trusted. Month two turns them into a forecast you actually read. Month three puts pricing and margin decisions on numbers instead of instinct. Truth, then direction, then decisions. Everything else a good one does in that window is in service of those three answers.

If that sounds plainer than you expected for the money involved, you’re reading it right. You’ve been sold vague before. You’ve sat on a call where nobody would name a price, a scope, or an end date, and left it knowing less than when you started. Wanting a beginning, an end, and a list of what you get isn’t you being difficult. That’s what evaluation looks like. So what are you actually buying, and by when? Fair question. Nobody gets to make you feel awkward for asking it.

Here’s what the vagueness has been costing you. Without a model, you carry the forecast in your body instead of a document. A quiet week reads as a warning. A good month reads as luck. You run the projection at 2am, in the dark, without the data, and then get up and make real decisions on the result. That’s exhausting in a way that more revenue doesn’t fix. It also gets more expensive the longer it runs, because every guess compounds into the next one.

Two things are being built at once here, and only one of them lives in a file. There’s the architecture, because a decision made on stale numbers is a guess wearing a spreadsheet. There’s also you, on a Tuesday, saying the new price out loud to a client you like. A first 90 days that only sorts files leaves the second of those exactly where it was. The architecture and the person have to arrive together. Which of the two has been running your quarter?

Prosperity First, based on Lummi Island, Washington, works with established US service business owners, usually somewhere between $250,000 and $2 million in revenue, who want CFO thinking without an open-ended relationship. This guide is for anyone comparing fractional CFOs, and that includes Shaneh F. Woods, the CFO and money coach behind Prosperity First. What follows is what you should be able to expect from any fractional CFO in your first 90 days, month by month, along with the milestones that tell you it’s working and the questions worth asking at the end of each one. Hold whoever you hire to it. That’s the point of writing it down.

TLDR: Before the full guide

Three months, three questions. What’s true, what happens next, and what should change. Inside: what each month should actually produce, the Federal Reserve data behind the squeeze you’re feeling, what the first 90 days isn’t, and a plain checklist for judging the whole thing on day 90.

Keep reading for the complete guide.

What this guide covers

Month One: Books That Are Current and Trusted

Month one is reconciliation. Plain, dull, load-bearing. Every account matched, every transaction categorized, every balance agreeing with the bank. The point is that nothing built in month two survives a ledger that quietly stopped updating in April. Truth first. The rest is theater.

Current and trusted are two different standards. A file can be perfectly current and still tell you nothing useful, because the categories were built to satisfy a tax return rather than to answer a business question. Trusted means you can ask which service line made money last quarter and get an answer you’d defend out loud. That usually means a chart of accounts rebuilt around how you actually earn. The difference between bookkeeping and financial strategy starts right here.

The Federal Reserve’s Small Business Credit Survey, published in March 2026 and fielded in late 2025, found that 54% of employer firms had difficulty paying operating expenses in the prior 12 months, and 50% reported uneven cash flow. Read those twice. Both are timing problems. Timing is a forward question, and it can’t be modeled on a ledger that stopped being current months ago.

You’ll feel this milestone before you ever see it in a report. It’s small and unromantic. You open the numbers on a Monday. No bracing first. Nobody throws a party for that. It’s still the foundation the next 60 days stand on.

  • Ask for reconciliation status on every account, including the ones you forget you have.
  • Ask what your chart of accounts is organized around: your tax return, or your service lines.
  • Set the standard now. Books closed monthly, on a named date, not when someone gets to it.

Month Two: A Forecast You Actually Read

Month two turns a clean record into a forward view. Cash first, then revenue. A model plain enough to show what lands, what leaves, and what’s left on the 15th and the 30th. Plain enough to decide from. Plain enough for a bad week.

Forecasting on instinct is getting less reliable, and the Federal Reserve Banks’ 2026 Main Street Metrics report is where you can watch it happen. Across a decade of the same survey questions, 94% of US employer firms reported at least one financial challenge in the 2025 survey year, up from 64% in 2017, while the share operating at a profit fell from 57% in the 2019 survey to 47% in the 2025 survey. That won’t tell you what your own business does next quarter, and no national survey can. What it does show is how many US owners are currently absorbing the gap between what lands and what leaves, using whatever’s nearest to hand. That’s a timing problem, and timing is exactly what a model is for.

The clearest reading of that decade-long slide sits close to home. Among employer firms with $100,000 to $1 million in revenue that faced financial challenges, 58% used the owner’s personal funds and 49% drew down cash reserves, in Federal Reserve data published in April 2026. That is a personal balance sheet doing the work of a line of credit. A runway model makes that visible while it’s still a choice. Before it hardens into a habit.

The milestone here is whether you open it. A forecast you read every week changes what you say yes to. Weekly beats perfect. If you’re still weighing whether this is even the right season to bring someone in, when to hire a fractional CFO is the earlier question to settle.

  • Ask to see the forecast format in month two, while you can still say it’s unreadable.
  • Agree the cadence you’ll genuinely keep for looking at cash, and keep it.
  • Name the two decisions this quarter the forecast has to be good enough to carry.

Month Three: Pricing and Margin, Decided With Numbers

Month three is where the numbers get spent. Pricing and margin, service line by service line. What each offer costs to deliver, what it returns, and which one is quietly funded by the others. That last one usually surprises people.

Among employer firms with $100,000 to $1 million in revenue that faced financial challenges, 50% raised the prices the business charges, per Federal Reserve data published in April 2026. Price is the most common lever those owners reached for, and reaching for it under pressure is the problem, because it tends to get pulled in a hard month with no margin math under it. Month three is where you pull it on purpose, with the delivery cost sitting in front of you.

Capacity is the other half of that math. What you can deliver without borrowing from next week sets the ceiling on what any price can do. Capacity Determines Cash, as Prosperity First puts it. If you’re still weighing which kind of help you actually need, a fractional CFO or a money coach is the question to settle beside this one.

This is also where a bounded engagement earns its shape. Prosperity First publishes a 90 Day CFO Intensive at a $9,000 one-time fee, with monthly options beside it. Whoever you hire, get the end date and deliverables in writing. Then judge them on the day.

There’s a difference between a decision you made and a decision you can account for, and it’s worth naming even though it never belongs in a scope document. The numbers do not get kinder in 90 days. Nobody can promise you an outcome. What changes is that Tuesday’s decision has a number under it, and you know exactly where that number came from. That’s the argument for doing the work in this order, and it’s the one Prosperity First makes. Ninety days won’t make the money easier. It’ll make it yours.

  • Ask for margin by service line, not only overall profit.
  • Bring your delivery capacity, in hours, to the pricing conversation before you set a number.
  • Agree now what you’ll decide on day 90: continue, pause, or stop.

Ready to hold someone to this?

Take this month-by-month list to whoever you’re considering and ask them to write their version of it down. If you want to see how Prosperity First does that, the scope and the live prices are already published on the fractional CFO page, so you can read the work before you talk to anyone about it.

If you’d rather have a conversation than a proposal, book a Clarity Call. Thirty minutes, a resonance check rather than a sales call, with no obligation waiting at the end of it.

Frequently asked questions

Q: What does a fractional CFO actually do in the first 90 days?

A: In the first 90 days a fractional CFO makes the books current and trusted, builds a cash and revenue forecast you’ll actually read, and turns pricing and margin into decisions made with numbers. Month one is truth, month two is direction, and month three is the decisions themselves. Ask any provider to put that sequence in writing, with dates against it, so you can evaluate the work rather than take it on faith. Prosperity First brings 30+ years in finance and $1B+ in collective profits overseen to that kind of engagement.

Q: How do I evaluate a fractional CFO while the first 90 days is still running?

A: Grade each month against what that month was supposed to produce. Don’t wait until day 90 to form a view. At the end of month one, ask for reconciliation status on every account, and check whether the chart of accounts now answers a business question. At the end of month two, ask to see the forecast in the format you’ll actually be reading it in, while there’s still time to say it’s unreadable. At the end of month three, ask for margin by service line and a written pricing recommendation with the math attached. Two softer signals matter as much. How fast does an answer come back between sessions? Does it arrive in language you can use? A provider who explains your own numbers back to you, in words you could repeat to your team on Monday, is doing the job you hired for.

Q: Is a fractional CFO worth it for a $250,000 to $2 million service business?

A: It depends on how many of last quarter’s decisions were made without numbers under them. It also depends on what you are honestly comparing it against. A full-time CFO is an executive hire, and a business in the $250,000 to $2 million band isn’t carrying an executive salary line, so that isn’t the live alternative. At your size, the realistic alternative to a fractional CFO is no CFO at all, with instinct sitting in the seat instead. For some owners that’s a fair trade for another year. For others, it’s the most expensive line item in the business, and it never appears on the profit and loss. The honest test is simple. Count the decisions you’d want to defend with a number, and count how many you could.

Q: What should exist on day 90 that didn’t exist on day 0?

A: Four things: reconciled books you trust, a forward model for cash and revenue, a margin picture by service line, and a documented decision about what happens next. All four, in your hands. Ask who owns those files, in writing, before you start, because the answer tells you a lot about the relationship. It’s also worth naming the boundaries. This is strategy work. Bookkeeping cover and tax work sit elsewhere, and no engagement anywhere can promise you a financial outcome. What it can do is move your decisions off instinct and onto numbers you helped build. If you reach day 90 and can’t point to those four things, you have your answer about whether to continue. That’s the quiet advantage of a deadline.
