The First 90 Days With a Fractional CFO: Deliverables and Review Points

A fractional CFO engagement becomes easier to evaluate when the first quarter has visible outputs. A founder should be able to explain what changed in the numbers, which decisions became clearer, and what the finance team can now repeat without an emergency. A calendar full of meetings does not answer those questions.

This is a suggested operating plan for a company that has appointed a fractional CFO and needs to organize the first 90 days. It is an editorial framework, not a promise that every business can complete a finance transformation in three months. The starting condition of the books, available support, and urgency of upcoming decisions should determine the schedule.

If you are still deciding what kind of support to hire, start with what a fractional CFO does. Here, the focus is what happens after the appointment.

Before day one: agree the mandate and the available capacity

Write down the three decisions the CEO needs help making. Examples include whether an approved hiring plan fits the operating budget, which business line deserves more investment, or what information a forthcoming board meeting requires. Keep the wording specific enough that the CFO can identify the necessary inputs.

Then map the work beneath those decisions. Who reconciles accounts? Who supplies the sales forecast? Who owns payroll data? Who approves assumptions? A senior finance leader may direct this work without personally performing every task. If bookkeeping cleanup is required, it needs an owner and allocated capacity of its own.

Agree the executive's availability, regular meeting time, document access, and escalation route. Share information through approved company systems with permissions appropriate to the work. Avoid building the entire engagement around the founder forwarding files from a personal inbox.

A practical first-quarter map

The phases can overlap. A pressing board deadline may require a provisional report before the accounting cleanup is finished. Label the report's limitations clearly and establish when it will be corrected.

Days 1–30: establish a trustworthy starting point

Begin with an inventory of available records and their condition. The CFO should be able to identify the most recent completed accounting period, material unresolved reconciliations, missing obligations, and inconsistencies between operational systems and the financial records. The output should explain what is dependable, what is provisional, and what cannot yet be concluded.

Ask for a short issue register rather than a long presentation. Each entry should have an owner, an action, a due date, and a description of the decision it affects. An unexplained balance matters because it can change a decision; the label alone is not useful to a founder.

A first cash view should distinguish confirmed balances and commitments from assumptions. Sales pipeline, signed revenue, invoicing, and cash collection are different events. The CFO should explain which inputs are used and why. This article does not prescribe a cash target or investment decision; it asks for a process that makes the underlying information inspectable.

Set a close process the existing team can maintain

A reporting deadline should come with a responsibility map. The bookkeeper or accounting team may prepare records, the CFO may review them, and the CEO may approve decisions arising from them. Decide where exceptions are recorded and how unresolved items are reflected in the report.

Avoid making a fast close the only success criterion. A report delivered earlier but filled with unexplained changes can make decision-making worse. Ask whether the same definitions were used, whether changes can be traced, and whether the person receiving the report understands the limitations.

For a small team, one consistent monthly review can be more useful than a complex dashboard nobody updates. The appropriate design depends on the actual volume and complexity of the business.

Days 31–60: build a forecast around operating assumptions

The next step is a forecast that connects to how the company works. The important conversation is about assumptions: hiring timing, customer starts, collection patterns, delivery capacity, and planned commitments. A spreadsheet should make those assumptions visible rather than hiding them inside unexplained formulas.

Ask the CFO to separate an agreed operating case from alternatives. A scenario is a way to examine a question, not a prediction that the question will resolve in a particular direction. The leadership team should understand which assumptions differ and which actions remain within its control.

As an illustration, suppose a company is considering adding a delivery team before a large customer begins work. The useful output is a comparison of timing, commitments, and capacity under stated start-date assumptions. The example is hypothetical; it does not establish what another company should spend or how much cash it should retain.

Build a reporting pack that leads to a decision

A short pack might contain recent results against the agreed plan, the updated forecast, unresolved information gaps, and two or three decisions for the leadership team. Put the requested decision beside the evidence supporting it. This makes the board or management meeting easier to prepare for and easier to follow up.

Kruze's discussion of remote CFO support for board meetings describes reporting and forward-looking preparation as part of that role. Use this as service context, not as proof that a particular provider will deliver a better result for your company.

Record decisions after the meeting. A useful log states the decision, accountable person, next review date, and the condition that would trigger reconsideration. It prevents the same unresolved question returning every month with a different chart.

Days 61–90: test whether the process survives a normal month

By the third phase, the company should try running the agreed reporting cycle with ordinary staff availability. Can the team produce the inputs? Can the CFO explain a variance without reconstructing the entire model? Can the CEO find the current approved version and the assumptions behind it?

Pay attention to dependencies on one person. If only the external CFO understands the model, the engagement has created a continuity risk. Ask for readable model notes, access held by the company, and a clear handover process. This does not require every employee to become a finance specialist.

Burkland's service-package overview identifies recurring planning and reporting activities within fractional CFO work. Your review should translate that broad scope into the specific outputs your agreement actually includes.

What to evaluate at the 90-day review

Review the engagement against the starting mandate. Are the original questions now easier to answer? Which information gaps have closed? Which remaining gaps require accounting capacity, operational discipline, or a different specialist? Distinguish work completed by the CFO from changes the wider company has not yet implemented.

Use a small set of observable measures: delivery of the agreed pack, unresolved issues with named owners, documented forecast assumptions, and decisions reached with the new information. Do not treat a better-looking dashboard or an unsupported claim about money saved as evidence of value.

Revisit the next quarter's scope explicitly. A company may need ongoing executive support, a narrower review cadence, or more hands-on accounting capacity. Compare engagement structures before treating a change in hours as an equivalent change in service.

Turn the plan into an agreed working document

Send the proposed phases to the appointed CFO and ask what should change given your starting position. A useful answer should identify dependencies and sequence the work. It should not promise that every accounting, reporting, and planning problem will disappear by an arbitrary date.

For companies still building a shortlist, explore fractional CFO providers or request an introduction. Share the outcomes you need and the condition of your current finance function so that the first conversation can address the actual work.
