Rule of 40: 28%. Gross margin plus FCF margin remains below threshold for healthy SaaS. This is a headwind on the efficiency story and will need framing on slide 4.
How the practice works
One senior CFO. One analyst with memory. One reviewed package.
The operational steps behind “board-ready in 90 minutes” — from trial balance in to CFO-approved package out — and the guardrails that keep Marlow out of trouble.
The monthly workflow
What actually happens between close and board meeting
01
You drop the data.
Trial balance, billing export, cap table, budget. CSV, QuickBooks, Xero, NetSuite, Ramp, or Stripe pull. If your books aren't closed, the workflow pauses — Marlow will not produce variance commentary on unreconciled data.
02
Marlow drafts the package.
Metric cards computed with explicit formulas and inputs. Variance commentary written against your stored board preferences. Executive summary drafted in your confirmed narrative style. Every figure has a lineage back to the source row.
03
Your CFO reviews in ~60 minutes.
Inline edits on the narrative. Approve, reject, or reframe variance calls. Mark an anomaly as “ask the founder” rather than guessing. The system refuses to export a package with unresolved blocks.
04
Export when — and only when — everything reconciles.
PDF, board deck, and dashboard must agree on every metric before the export button enables. No “Gross Margin 0.0%” surprise on slide 6. No delivery from in-review.
05
Every edit becomes a signal.
The CFO's inline edits are captured as attributable signals — terminology, framing, emphasis, exclusions — dedup'd so the same preference doesn't pile up as 16 pending items, and applied to next month's draft.
06
Post-meeting capture.
After the board call, commitments, revisit triggers, and open questions land in the decision ledger. Next month's package opens with the ones that are still active.
How a correction becomes future behavior
One specific example, end to end
Rule of 40: 41%. Operating-margin variant, excluding the multi-cloud migration capex that lands in Q2–Q3. FCF margin badly understates the story here. This is a temporary investment, not a headwind; the board has been briefed on migration cost at the last two meetings.
Rule of 40: 43% (operating-margin variant, per the CFO's February framing). Multi-cloud migration capex excluded through Q3 — revisit when migration completes. The investment call has been briefed to the board twice, flagged here only as continuity.
The edit wasn't a one-time fix. It became a stored signal with a revisit trigger. Every month the migration capex lands, Marlow leads with the right framing without anyone having to re-explain it.
What Marlow actually remembers
Four concrete kinds of memory
Metric definitions
NRR excludes your services revenue. ARR bridge flows bookings → starting ARR → net new → churn → ending ARR. Rule of 40 uses the operating-margin variant for this client. Every definition is inspectable.
Board preferences
Your Accel partner reads the first three pages and searches for burn. Your independent wants the hiring-plan variance called out. The framing lands on those hot buttons before you ask.
Prior decisions
“Delay the Series B fundraise to Q3.” “Don't break out vertical #2 revenue yet.” “Exclude the one-time legal settlement from gross-margin narrative.” Each decision has a rationale, an owner, and — where relevant — a revisit trigger.
Narrative style
The executive summary leads with the conclusion. Variance is framed as investment vs. headwind, not as noise. Bullet lists stay under five items. Your voice, not a template voice.
The guardrails
What never leaves the practice without a CFO review mark
Marlow drafts. The CFO signs. The workflow refuses to let the two steps merge.
- No export from in-review. Delivery state machine blocks the export button until every section has a CFO approval mark.
- Balance sheet must balance. Assets ≠ liabilities + equity, the package does not ship. Not as a soft warning — as a blocker.
- No portal link until you approve. Founder-facing portal messages require explicit CFO send, not a scheduled auto-push.
- Metrics with structural gaps flagged, not hidden. If “Gross Margin” can't be computed because the COGS mapping is incomplete, the package says so. We don't print 0.0%.
- No unreviewed board narrative. Executive summary, variance commentary, metric interpretations — all carry a review mark before PDF generation.
- Unresolved 40%+ variances block delivery. We'd rather be a day late than ship a story we can't defend in the board room.
