DECISION GUIDE · FINANCE LEADERSHIP
Do I Need a Fractional CFO?
The question is not whether you need financial help. It is what kind.
Most founders know when finance feels like a bottleneck. Fewer know whether the fix is a better bookkeeper, a fractional CFO, or a full-time VP Finance. The answer depends on stage, complexity, and what decisions are actually being made without a senior financial voice in the room.
HOW TO USE THIS
Eight categories. Score each 1–5.
01
For each of the eight categories below, read the five score descriptions and pick the one that most honestly reflects where you are today. Don’t aspire — describe.
02
If you’re between two scores, pick the lower one. Investors will read the gap, not the aspiration.
03
When you finish, the running total updates live. Your total falls between 8 and 40.
04
The interpretation at the end translates that total into what it means and where to look first. Categories you scored lowest are usually the highest-leverage places to spend the next 30 days.

HOW TO USE THIS
Four signals. One decision.
Company profile. Stage, capital raised, team size, and current finance function. These set the baseline.
Financial infrastructure. How fresh is your model? Who owns the books? Where do the numbers live?
Strategic needs. Are you raising? Do you have a board? What financial question keeps you up at night?
The decision. Based on your answers, this guide maps you to the right kind of financial support — not the most expensive.
This guide reflects the same decision framework Centripetal uses in its diagnostic conversations with founders. The four outcomes below are not sales categories — they are honest assessments of what different companies actually need.
THE FOUR SIGNALS
What determines the right kind of financial support
Your stage and capital raised set the floor. Your financial infrastructure determines whether the current setup can support the next 12 months of decisions. Your strategic needs — fundraising, board reporting, pricing, hiring — determine whether those decisions require senior judgment or better execution of existing processes.
Signal 1 — Stage and Capital
Pre-revenue companies with less than $1M raised rarely need a fractional CFO. They need clean books and a founder who understands unit economics. Post-Seed companies with $2-7M raised and 10-30 employees are the inflection point — financial complexity outgrows the bookkeeper, but a $370K VP Finance hire is premature.
Signal 2 — Current Finance Function
If the founder is still the primary financial decision-maker and the bookkeeper handles everything else, there is a gap. The question is whether that gap is operational (better bookkeeper, controller) or strategic (someone who can model scenarios, negotiate with investors, and build the financial story).
Signal 3 — Model Freshness
If the financial model has not been updated in 90+ days, or if one does not exist, that is a structural gap. Investors, board members, and hiring decisions all depend on a model that reflects current reality. The person who owns the model needs to understand the business, not just the spreadsheet.
Signal 4 — What Keeps You Up at Night
Cash timing problems, pricing uncertainty, hiring confidence, and investor readiness are all signals that financial decisions are being made without adequate support. The severity and combination determine the right intervention.
SECTION 2
The Four Outcomes
Each outcome is an honest assessment, not a sales pitch. Some companies genuinely do not need a fractional CFO.
Outcome 1 — You Are Fine for Now
Pre-revenue or early-seed companies with clean books, a founder who understands the numbers, and no immediate fundraise or board obligations. The right move is to keep the bookkeeper, learn the finance fundamentals, and revisit when complexity increases.
Outcome 2 — Upgrade Your Bookkeeper or Hire a Controller
Companies where the gap is primarily operational — the books are messy, reconciliation is inconsistent, the model does not exist or is stale. The fix is better execution of financial basics, not strategic financial leadership. A strong bookkeeper or part-time controller closes this gap at a fraction of a fractional CFO cost.
Outcome 3 — Fractional CFO Support
The sweet spot for companies with $2M–$10M in funding, 10–50 employees, and financial decisions that require senior judgment — fundraising strategy, board reporting, pricing, hiring plans, cash management. The complexity exceeds what a bookkeeper can handle, but the company is not at the scale where a full-time VP Finance is the right investment. An embedded fractional CFO provides 10–20 hours per week of the judgment and infrastructure a founder needs without the $370K+ fully loaded cost.
Outcome 4 — Full-Time VP Finance
Series B+ companies with 50+ employees, multiple product lines, complex revenue recognition, and a board that expects institutional-grade financial operations. At this scale, the company needs a dedicated executive who lives inside the business full-time. A fractional CFO can serve as the bridge — building the financial infrastructure and helping recruit the right full-time hire.
Q: When should a SaaS founder consider a fractional CFO?
A: The inflection point is usually post-Seed with $2-7M raised, 10-30 employees, and financial decisions that outgrow the bookkeeper — fundraising, board reporting, pricing, or cash management.
Q: Is a fractional CFO just a cheaper version of a VP Finance?
A: No. It is a different model. A fractional CFO provides embedded senior financial judgment for 10-20 hours per week. A VP Finance is a full-time executive. The right choice depends on complexity and scale, not budget.
Q: What if I just need better bookkeeping?
A: Then hire a better bookkeeper or a part-time controller. Not every financial gap requires strategic leadership. The honest answer is sometimes the simplest one.
Q: How long do fractional CFO engagements typically last?
A: The average engagement at Centripetal is 2.5 years. These are not short-term projects — they are embedded relationships that evolve with the company.
Q: Can a fractional CFO help with fundraising?
A: Yes. Building the financial model, preparing the data room, structuring the investor narrative, and managing the diligence process are core fractional CFO functions at this stage.
