What a Fractional CFO Does Each Month: The Actual Schedule

Fractional CFO services, done properly, come on a schedule: a cash forecast updated every week, a call each month about what changed and what to do about it, one decision-grade report each quarter, and a tax plan in November built from closed books. That’s the deliverable. If a proposal for CFO services can’t tell you what happens in week two of the month, it’s describing a title, not a job.

We run an accounting firm, and we wrote earlier about when a business needs a bookkeeper, a controller, or a CFO. This is the next question owners ask: fine, what does the CFO actually do each month? Here’s the calendar.

Do I need a CFO for my small business?

Quick test before the schedule. You need one if you’ve had at least one year that was busy, maybe your busiest, and somehow wasn’t profitable, and you couldn’t say why. Or if you’re making decisions about hiring, pricing, equipment, or a second location by looking at the bank balance. Or if the tax bill surprises you every April. Any of those means the numbers exist but nobody is reading them for you.

Most businesses hit that point somewhere between $1 million and $3 million in revenue. It doesn’t require a full-time hire. It requires a few hours a month, on a schedule, from someone whose only job in those hours is to read your numbers and tell you what they mean.

Week one: the close and the forecast

The month starts with last month’s books closing by the 10th. Every account reconciled, payroll and loans tied to their documents, questions answered, reports out. That’s bookkeeping, not CFO work, but nothing in the CFO’s month works without it.

The moment the close lands, the CFO does two things. First, reads the cash flow statement before the P&L, because profit says whether the model works and cash says whether you survive the quarter. Second, updates the 13-week cash forecast with the closed month’s actuals as the new starting point.

The forecast then gets touched every week, not just week one. Twenty minutes each Monday: replace last week with actuals, push the late invoices forward, add the new bills, look at the low point. If the low point moved, you hear about it that day, not at the monthly call.

Week two: the monthly call

One call, forty-five minutes to an hour, with a one-page agenda sent the day before. The agenda has three sections, every month.

What changed. Three or four numbers that moved since last month and why. Gross margin dropped two points because the produce contract reset. Labor as a percent of sales is up because the new hire started before the revenue did. Receivables over 60 days doubled and it’s two specific customers.

The forecast. Where the low point is, whether it’s a timing problem or a structural one, and what, if anything, to do this month about it.

One decision. Every call ends with one thing you’re going to decide or do. Call those two customers. Approve the price increase on the maintenance line. Hold the truck purchase until the forecast clears week nine. Not a list of ten. One.

Owners don’t need more information. They need someone to sort it and hand them the one thing that matters this month.

Week three: the operating number

Every business has one operating number that decides whether it makes money, and it isn’t on the standard P&L. A restaurant has prime cost. A contractor has job margin by job type. A service business has margin by service line. A landlord has cash-on-cash by door. An agency has utilization.

Week three is when the CFO looks at that number, from the closed books, and compares it to last month and to the same month last year. Most months it’s a paragraph in an email. Some months it’s the reason for the next quarterly report.

Week four: the estimate and the look ahead

Before the month ends, the CFO checks the tax picture: year-to-date profit through the last closed month, run through the tax, against what’s been paid in estimates and withholding. Not to file anything, but to know whether the next estimate is on track, so the fourth-quarter payment on January 15, 2027 isn’t a surprise, and so the S-corp salary conversation happens in October instead of the last week of December.

Then a look at next month’s calendar: a third payroll, an insurance renewal, an estimated tax date, a seasonal dip. Those go into the forecast so the next monthly call isn’t about something that was foreseeable.

Once a quarter: one decision-grade report

Every quarter, one report built to answer one question, with the dollars attached. Margin by service line: which service is underpriced and what a 12% increase on it is worth per year. Job costing by job type: which type is estimated at 30% and delivering 15%. Real labor cost including contractors: what it means for pricing and whether anyone should convert to payroll. The cash conversion cycle: how much cash the next $100,000 of monthly growth will consume.

The report is a page or two. The meeting to go through it is an hour. The decision that comes out of it is usually the one that pays for the year of advisory, because it’s a price change, a service you stop selling, or a hire you make with a number behind it.

November: the tax plan

One month gets its own deliverable. In November, with ten closed months and a projection for two more, the CFO builds the year-end plan: the fourth-quarter estimate from real profit; whether to buy equipment before December 31 (Section 179 and 100% bonus depreciation both apply to qualifying property acquired this year); the S-corp salary versus distribution split; a bonus run through payroll; retirement plan contributions; and which of those the cash forecast can actually absorb. That plan goes to the tax preparer, and the return in March becomes a report on decisions already made.

Done in November, every one of those is a choice. Done in April, they’re history.

What a CFO does with this number

Each of those touchpoints produces a number, and the CFO’s job is to turn every one into a sentence with a dollar sign in it. Not “your gross margin is 34%.” Instead: “your margin is 34% and it was 37% last year; the difference on your revenue is about this much a year, and here’s the one line it’s coming from.” Not “receivables are up.” Instead: “these two customers owe this much over 60 days, and if they don’t pay by the 20th, week six goes negative, so here’s who to call today.”

The schedule matters because the numbers are perishable. A margin problem found in week one of the following month gets fixed. The same problem found on the tax return in April was a year of margin you didn’t get.

Where we come in

Our fractional CFO work runs on exactly this calendar, and it sits on top of a monthly close we do ourselves, with payroll in-house, so the numbers the CFO reads are numbers we closed. Weekly forecast, monthly call with one decision, one quarterly report with dollars on it, the November plan, and a tax return in the spring that reports on all of it. It’s an add-on to bookkeeping, not a separate firm.

If you’ve had a busy year you can’t explain, or you’re making real decisions off the bank balance, reach out. We’ll start with a two-hour diagnostic and tell you what the first monthly call would say.

Frequently asked questions

What’s the difference?
A bookkeeper records what happened, a controller makes sure it’s right and on time, a CFO uses the numbers to decide what happens next.

When does a business need a CFO?
Usually between $1M and $3M in revenue, a few hours a month, after a busy year that somehow wasn’t profitable.

What do fractional CFO services include?
A weekly cash forecast, a monthly call on what changed, one decision-grade report a quarter, and a tax plan in November.
