Fractional CFO for software companies
SaaS finance is its own discipline - every dollar of bookings has to be sliced into deferred revenue, recognised on a contract clock, and translated back into ARR, NRR and CAC payback before it means anything to a board.
The founders who run a tight ship know that gross margin, magic number and rule of 40 aren't reporting metrics - they're operating decisions about pricing, sales hiring, paid acquisition and infrastructure spend. A fractional CFO who has lived inside SaaS understands which lever to pull at which stage, and what investors will actually look at when the next round comes around.
Software is our home turf. We have built the FP&A function, the cohort waterfall and the board pack for SaaS businesses from seed through growth, and we know how to make the model say what the business actually does.
Choose a fractional CFO that understands software
Read every ARR signal
Gross new ARR, expansion, contraction and churn each tell a different story about the business, and most reporting blurs them into one line. We build the cohort and NRR view that separates pricing power from churn risk, and lets the team plan sales coverage and pricing changes against real evidence.
Plan around CAC payback
Sales hiring decisions, paid spend and pricing all collide in CAC payback and magic number - get one wrong and burn moves a quarter ahead of plan. We model unit economics by segment and channel, so the cash runway lines up with realistic ramp curves rather than top-of-funnel hope.
Board-ready in days
SaaS investors expect a board pack that ties ARR bridge, P&L, cash and KPIs in one consistent story. We build the template, own the close cycle with your accountants, and produce the pack monthly so fundraising conversations don't need a six-week scramble to reconstruct numbers.
Embedded for the next round
Most SaaS founders need a CFO who can run finance today and run a fundraise in twelve months. We do both, with the same model and data room, so when the round starts the lift is shaping the story - not rebuilding the numbers from scratch.

Financial modelling for software startups
We work with software founders to build investor-ready, KPI-driven financial models.
We dive deep into your company and sector specifics, to build a custom-made financial model driven by operational KPIs, requiring a minimal learning curve and time spent on monthly updates.
ARR waterfall
Bookings to billings to revenue, broken into new, expansion, contraction and churn by cohort and product line. Translates contract-level activity into the metrics investors actually look at.
NDR & GRR cohorts
Net and gross retention measured cohort by cohort, with the upsell and churn drivers separated. Shows whether the business is compounding on the existing base or relying on new logos to mask leakage.
Magic number & rule of 40
Net-new ARR per dollar of S&M, plotted against rule-of-40 trajectory. Calibrates sales hiring and paid-spend decisions to where the business sits on the efficiency curve.
CAC payback by segment
Fully-loaded CAC and payback measured by segment, channel and motion - inbound versus outbound, SMB versus mid-market. The blended average is usually hiding a profitable segment and a money-losing one.
Sales capacity model
Quota, ramp time, attainment and territory coverage tied back to the ARR plan. Tells you how many reps you actually need hired by when to hit next year's number.
Cap table & SAFE stack
Pre/post-money cap table with SAFE conversions, option pool top-ups and waterfall scenarios. Founders see exact dilution before agreeing to round terms.
