Fractional CFO for SaaS:
From Seed to Series A and Exit

Most SaaS founders hit a point where the spreadsheets break, the board starts asking for metrics you cannot produce, and investors want a financial narrative you have not built yet. That is not a business problem. It is a CFO problem.

Consult EFC embeds as your Fractional CFO — tracking the SaaS metrics that matter, building investor-grade models, managing your runway, and getting you Series A ready without the full-time overhead.

"SaaS investors are not just buying your product. They are buying your unit economics, your retention, and your growth efficiency."

MRR, ARR, churn tracked and investor-ready

The metrics investors will demand

We track, model, and defend every SaaS metric that matters

These are not vanity numbers. They are the benchmarks any serious investor will stress-test before committing capital.

ARR / MRR

Revenue Recognition

Correctly calculated and structured for investor due diligence.

CAC : LTV

Unit Economics

The ratio that tells investors whether your growth is sustainable.

Churn

Retention Analysis

Revenue churn and net revenue retention broken down by cohort.

Rule of 40

Growth Efficiency

The industry gold standard benchmark for SaaS health.

We also track: Gross margin, payback period, magic number, DAU/MAU, NPS correlation, expansion MRR, quick ratio, and burn multiple — all structured for investor-grade reporting.

Sound familiar?

The finance problems that hold SaaS founders back

Issue 01

MRR looks good but runway is tighter than expected

Revenue is growing but cash is not keeping pace. Burn rate is not being managed with the precision a Series A investor will expect.

Issue 02

Investors asking for metrics you cannot track cleanly

CAC payback, NRR, cohort analysis — the questions are coming and your current spreadsheets cannot produce investor-grade answers.

Issue 03

Going into investor meetings without a CFO

VCs will probe your model in detail. Walking in without a qualified CFO to defend those numbers costs you valuation and credibility.

Issue 04

Gross margins below the expected 70%+ benchmark

SaaS investors expect high margins. If yours are lower, you need a clear story and a plan to optimise them before the raise starts.

Issue 05

Revenue recognition is not structured correctly

Subscriptions, upfronts, and multi-year contracts are often booked incorrectly, killing deal confidence during due diligence.

Issue 06

Full-time SaaS CFO is the wrong commercial move

A qualified SaaS CFO commands £150k+. A fractional model gives you that calibre of leadership at 15% of the cost.

Common questions from SaaS founders

When is the right time to bring on a SaaS Fractional CFO?
The typical trigger is hitting £1M ARR or beginning serious preparation for a Series A raise. At that point, your financial complexity genuinely outgrows standard bookkeeping. Proper CFO oversight ensures your numbers are clean when it matters most.
How is this different from hiring a finance contractor?
A contractor executes tasks like payroll and statutory accounts. A Fractional CFO makes strategic decisions, attends board meetings, and takes ownership of financial outcomes. We lead the function; they execute it.
Do you replace my existing accountant or bookkeeper?
No. We work alongside them. We take their output and turn it into forward-looking financial intelligence, often improving the quality of their inputs by standardising the chart of accounts for SaaS.
Do you help with Series A fundraising directly?
Yes. We build the financial model, prepare the data room, and clean up issues before investors find them. Kish attends meetings to field technical questions and defend the financial narrative.
What accounting software do you work with?
We are technology-agnostic but primarily work with Xero, QuickBooks Online, and NetSuite. We also implement planning tools like Fathom or Mosaic to provide real-time SaaS visibility.
Why not just hire a full-time SaaS CFO?
At Seed or Series A, £150k+ plus equity is rarely the right capital allocation. A fractional engagement gives you the same calibre of leadership at a fraction of the cost, scaling as you evolve.
