Fractional CFO for Software & SaaS
SaaS finance is its own discipline. A fractional CFO who understands the real economics — and can fix the systems feeding your numbers, too.
What a fractional CFO brings to a SaaS company
SaaS finance is its own discipline. Recognized revenue rarely matches cash, the metrics investors care about are not on the standard P&L, and the difference between a fundable story and a confusing one is almost entirely in how the numbers are framed. Founders usually do not need more bookkeeping — they need someone who speaks ARR, runway, and the board's language.
A bookkeeper records what happened. A fractional CFO tells you what it means and what to do next — and for software & SaaS businesses, that judgment is the difference between scaling on purpose and scaling into a wall.
What I own for software & SaaS businesses.
The specific finance work that moves the needle in this industry — not a generic CFO checklist.
01 ARR / MRR & SaaS metrics
ARR, MRR, net and gross retention, CAC, LTV, churn, and magic number — defined consistently and reported the way investors expect to read them.
02 ASC 606 revenue recognition
Ratable vs. point-in-time recognition done right, with deferred revenue and contract treatment that survives diligence.
03 Burn & runway
Cash burn and runway modelled against hiring, pipeline, and growth scenarios so you always know how many months you really have.
04 Board & investor decks
Board reporting and investor updates that tell a coherent financial story instead of a pile of disconnected charts.
05 Fundraise & M&A support
Models, data rooms, and the financial narrative behind a raise or an exit, built to hold up under scrutiny.
Real operating experience in this world.
This is squarely in my wheelhouse. I lead strategic finance and FP&A for Series B/C SaaS companies across the US and Canada — 3-statement models, driver-based forecasting around ARR, services revenue, headcount, utilization, and gross margin, ASC 606 revenue recognition, board and investor reporting, and an AI-native finance stack. I also led a sell-side M&A exit (a venture-backed company, acquired by a strategic acquirer), so I have built the model that gets a company through diligence.
Most fractional CFOs can’t fix the software feeding your books. I can.
Beyond the model, I am comfortable owning the finance tooling end to end. Steel City CFO's systems experience means I can stand up or clean up the stack — billing, accounting, and the reporting layer — so your SaaS metrics come out of a system instead of a heroic monthly spreadsheet rebuild.
That second service line — Financial Systems Architecture — is what makes the CFO work stick at a SaaS company: when billing and the systems behind it are clean, your ARR, deferred revenue, and burn come straight out of the stack instead of a spreadsheet rebuild.
