What a Fractional CFO Actually Does in Month 1
If your fractional CFO can not show you 10 specific artifacts by day 30, you hired the wrong person.
Most founders sign a $15K-a-month engagement with a fractional CFO and don't know what to expect on the other side. "We're getting financial leadership" is what the contract says. What actually arrives is wildly variable. Some firms ship a thick stack of deliverables in week one. Others spend the first two months "learning the business" and produce a Google Doc.
The difference shows up at day 30. A real fractional CFO has put 14 specific things in front of you. A bad one has had four "intro calls" and not much else.
This post is the checklist. It's not the only definition of a good first month — every engagement adjusts to the stage and the situation — but it's the floor. If 10 of these 14 aren't on your desk by day 30, raise it; if the response is hand-waving, fire and find someone else. The cost of a wasted month at this rate is roughly $5,000 of CFO retainer plus the opportunity cost of decisions made on bad data.
I'll walk through the 14 deliverables by the week they should land, then close with what month 2 and 3 look like so you can extrapolate.
The 14 deliverables, in delivery order
These are the artifacts. Each is a specific output, not a "we discussed it" line item.
| # | Deliverable | Week |
|---|---|---|
| 1 | Financial system audit (chart of accounts, close process, what's broken) | 1 |
| 2 | Cap table sanity check (errors, missing SAFE/note conversions, vesting) | 1 |
| 3 | Bank + cash reconciliation across all accounts | 1 |
| 4 | Trailing 12-month P&L cleaned and re-categorized for management view | 2 |
| 5 | Board-ready financial reporting template | 2 |
| 6 | KPI dashboard (≤10 metrics, refreshed monthly minimum) | 2 |
| 7 | Unit economics baseline (CAC, payback, LTV, gross margin by segment) | 2 |
| 8 | 13-week direct cash forecast, updated weekly | 3 |
| 9 | 12-month operating model, three scenarios (base/downside/upside) | 3 |
| 10 | Reconciliation between the 13-week and the 12-month (they must agree) | 3 |
| 11 | Burn rate, runway, burn multiple — all three computed on consistent inputs | 3 |
| 12 | Fundraising-materials review (if you're inside a raise window) | 4 |
| 13 | Month-1 retro: what's broken, what's fixed, what the next 60 days look like | 4 |
| 14 | A working relationship with your bookkeeper / controller — not a parallel one | 4 |
Now the per-week detail.
Week 1 — Audit the foundation
The first week is diagnosis, not strategy. Before a CFO can make decisions on your numbers, the numbers themselves need to be trustworthy. If they're not, the rest of month 1 looks different — the priority becomes cleanup, and the CFO usually says so out loud.
Deliverable 1: Financial system audit. A written summary of what software you're using (QuickBooks, Stripe, Mercury, Ramp, Gusto, etc.), what's clean, what's broken, what's missing. Common findings: 200+ uncategorized transactions, three different revenue recognition methods running in parallel, a chart of accounts that grew organically and now has 287 GL accounts. The deliverable is a 1-2 page memo plus a prioritized fix list.
Deliverable 2: Cap table sanity check. Pull your cap table (Carta, Pulley, or a spreadsheet). Look for: SAFE conversions that weren't processed at the priced round, vested vs. unvested founder shares that don't tie to the original agreements, missing option grants, post-money vs. pre-money confusion in earlier rounds. A real CFO finds at least one issue in 80% of seed-stage cap tables. The deliverable is annotations on your current cap table plus a remediation plan.
Deliverable 3: Bank + cash reconciliation. Pull every bank, credit card, payment processor (Stripe, Mercury, brokerage if relevant). Reconcile balances. Identify pending transactions, restricted cash, escrow. The output is a single-page cash position document with your real available cash — usually 10-30% different from what you thought it was.
If week 1 finds the books are months behind, the engagement pauses for cleanup. I've watched this happen and it's painful — you signed up for a CFO and you're getting a controller for 6 weeks first. Better than the alternative (building a model on bad data), but the founder needs to know up front.
Week 2 — Build the reporting layer
With the foundation triaged, week 2 is about making the numbers legible.
Deliverable 4: Trailing 12-month P&L, cleaned. Your QuickBooks-out-of-the-box P&L is usually unreadable for management decisions. The CFO re-categorizes line items into operating segments (sales, R&D, G&A, infrastructure), strips out one-time noise (legal fees for the SAFE, a single $40K cybersecurity insurance renewal), and produces a TTM view that actually shows what's happening in the business.
Deliverable 5: Board-ready financial reporting template. A 6-8 slide template for board updates: ARR + growth, burn + runway, unit economics, key OKR progress, cash position, capital plan. Not the entire board deck — just the finance section, with the math wired through so updating month-over-month takes 30 minutes, not 4 hours.
Deliverable 6: KPI dashboard. No more than 10 metrics. Refreshed at least monthly (weekly for revenue + cash). The 10 should be: MRR/ARR, net new ARR, gross margin, CAC, CAC payback, net retention, burn, runway, headcount, magic number (or rule of 40 if growth-stage). The deliverable is a single-page dashboard in whatever tool you'll actually look at — Google Sheets is fine.
Deliverable 7: Unit economics baseline. Computed on actual customer cohorts, not industry-average assumptions. CAC by channel. Payback by segment. LTV by tier. Gross margin by segment if you have multiple price points. The point isn't to have pretty numbers; it's to know which customer segment is profitable and which is burning cash, so you can do something about it in months 2-3.
Week 3 — The model and the forecast
Week 3 is the substantive output of month 1: a working financial model and a cash forecast that both agree with each other.
Deliverable 8: 13-week direct cash forecast. Every line item that will hit your bank in the next 13 weeks, by week. Payroll, rent, vendors, customer collections, tax payments, one-time hits. Updated weekly with variance against the prior week's forecast. This is the document that prevents missed payroll three months out — if you're not running one of these, you don't have visibility, you have hope.
Deliverable 9: 12-month operating model, three scenarios. Bottom-up build from current headcount and committed expenses. Three scenarios: base (your plan), downside (something bad happens — top customer churns, raise slips a quarter), upside (something good — bigger raise, faster sales ramp). Most founders have a one-scenario model. That's not a model; that's a hope memo.
Deliverable 10: Reconciliation between 13-week and 12-month. The 13-week and the 12-month must agree on the cash position in weeks 1-13. If they don't, one of them is wrong, and it's almost always the 12-month. The reconciliation makes both documents internally consistent.
Deliverable 11: Burn, runway, burn multiple — consistent inputs. Computed using the same definitions a Series A investor would use (covered in why your startup runway calculation is probably wrong and burn multiple benchmarks for Series A SaaS in 2026). One number per metric, with the inputs documented. No more "depends on which spreadsheet."
Week 4 — Strategy layer + retrospective
Week 4 closes the month. Whatever's left from the prior three weeks gets cleaned up; the strategic work begins.
Deliverable 12: Fundraising-materials review (if you're inside a 6-12 month raise window). A read of your existing deck, model, and data room with notes on what investors will push back on. Common findings: ARR computed on annualized last-month vs. true ARR, gross margin not adjusted for hosting costs, the burn multiple section is missing entirely, the model doesn't reconcile to the historical P&L. If you're not raising, this gets replaced with a "what's the next strategic decision" memo — usually pricing, hiring, or a market expansion call.
Deliverable 13: Month-1 retro. What was broken on day 1, what's fixed, what's still broken, what the next 60 days look like, what you (the founder) need to do versus what the CFO will own. Concrete. Dated. Not "we're making great progress."
Deliverable 14: Working integration with your bookkeeper or controller. This is the soft one but it matters. A bad fractional CFO runs in parallel to your existing finance function, duplicates work, and creates two sources of truth. A good one slots in — the bookkeeper closes the books, the controller manages the close calendar, the CFO uses the output. By day 30 you should see this loop running, not a stack of CFO-only spreadsheets disconnected from your accounting system.
What month 2 and 3 should look like (preview)
If month 1 was diagnosis + foundation, months 2-3 are when the engagement starts paying back.
Month 2 is usually: deeper unit-economics work (cohort retention curves, channel-level CAC), the first board update produced through the new reporting layer, the start of a hiring plan tied to the operating model, and any cleanup carrying over from week 1 (chart of accounts rebuild, cap table fixes filed).
Month 3 is when the model starts driving decisions instead of describing them. Pricing experiments calibrated against the unit economics. A go/no-go on a new market or product line. The first version of a Series A narrative if you're in the raise window. Cash forecasting gets to the point where you can sleep on a Sunday night before payroll.
If you're entering month 4 and your CFO is still doing "intro work," they're either underqualified or underpriced. Real fractional CFOs at the $15K+ tier compound fast — by month 3 you should be able to point to specific decisions that wouldn't have happened (or would have been worse) without them.
What this looks like in practice
A composite of three engagements, anonymized.
The call: $3M ARR SaaS, 25 people, 7 months from a Series A. The founder hired a fractional CFO three months ago for $12K/month and "is not sure what's being delivered." He sends me the contract and asks if we should start a new engagement.
First diligence pass. I pull the deliverables: a Google Doc titled "Q3 financial review" (last edited 6 weeks ago), one version of a P&L (incomplete, with two of three bank feeds unreconciled), no 13-week cash forecast, no 12-month model, no cap table review. The CFO has had 12 calls. Zero artifacts on the desk.
The honest answer. The current CFO isn't a CFO — they're a high-priced consultant. The founder isn't getting CFO output because the engagement was scoped without deliverables. Two options: rescope with a deliverables checklist (this one), give 30 days, evaluate; or end the engagement and start fresh with someone who agrees to ship the 14 in 30 days. Founder chose option two. The new engagement (not me — a referral) had 11 of 14 deliverables on his desk by day 28 and the missing 3 in flight by day 45.
The lesson. Fractional CFO engagements without deliverables become advice subscriptions. At $15K a month that's expensive advice with no artifact you can point to in 90 days. If your CFO isn't comfortable being held to a deliverables-by-week checklist, you have the wrong CFO.
A note on AI in 2026
You can run most of the diagnostic work (deliverables 1-4 and 6) through ChatGPT, Claude, or one of the cash-forecasting AI tools in about a day. They'll do it competently. They will not flag the cap-table issue that costs you 2% dilution in the next round, recognize that your "gross margin" excludes hosting costs the way investors actually compute it, or tell you that your two largest customers are on the same legal entity and your concentration is twice what your slide says.
The 14 deliverables are mostly artifacts. The value of the CFO is reading the artifacts for the things the artifacts don't say out loud. AI does the spreadsheet. The CFO tells you which spreadsheet to be worried about.
Three things you can do this week
If you have a fractional CFO and you're not sure they're delivering, run this 14-item checklist against what's on your desk today. You'll have an answer in 20 minutes — and if it's 4-of-14 instead of 10-of-14, you have an honest conversation to have this week, not next quarter.
If you don't have one yet and are wondering whether you should hire one, take the Raise-Ready Scorecard — the burn/runway and reporting dimensions tell you if you're at the stage where a CFO pays back fast or whether you'd be better served by a controller first (the controller-vs-CFO breakdown covers this in detail).
If you're sizing up a CFO engagement and want a second opinion on scope before you sign, book a 30-minute call. I'll walk through what a 30/60/90-day deliverables map looks like for your specific shape (stage, ARR, raise timeline) and help you scope a conversation with whoever you're considering. That's a free call. If we end up working together it's a fractional CFO engagement — flat-rate, deliverables-first, the 14-item checklist above is the floor.
If a real fractional CFO at $15K/month can't show you 10 specific artifacts in 30 days, the title is doing the work, not the person. The artifacts are how you know which one you hired.
