A complete 36-month SaaS financial model — cohort revenue engine, role-based headcount planner, Base/Optimistic/Conservative runway scenarios, and an executive KPI dashboard — wired together in five named tabs. No fragmented spreadsheets. No disconnected assumptions. No "we'll fix it next quarter."
When revenue, headcount, churn, OPEX and cash runway each live in their own file, the answer to "what happens if we hire two AEs?" depends on which spreadsheet you opened first. Decisions get made on numbers that don't reconcile — and nobody notices until the board asks.
Starting cash lives in one sheet. ARPU in another. CAC in a third. Change one number and you have to remember to update six places you forgot you had.
Hand-keyed cohort retention tables stop matching the underlying logic the moment a single assumption moves. The board sees a number, but no one can explain it.
"What if churn drops 2 points?" means a full copy-paste of the whole model into a new tab — which someone will forget to delete before the next board update.
Cash balance gets eyeballed from a bank statement plus a back-of-envelope burn multiple. The actual zero-cash date is rarely the one in your head.
Salary inflation, benefits and 15% payroll-tax assumptions sit in HR's spreadsheet. The revenue model has no idea they exist. Adding a new hire feels free.
LTV and CAC are computed at quarter-end from exported CSVs. By the time leadership sees them, the inputs have already moved.
The cost isn't the spreadsheet. The cost is the decision you made last Tuesday because the number looked plausible — and the one you didn't make because the model said it wasn't safe.

The control panel. Starting cash, ARPU, CAC, monthly traffic, conversion rate, gross margin, churn, benefits, payroll tax, salary inflation — every global lever lives here and only here.
36 months of traffic, conversion, new customers, MRR, expansion, churn, retention and cohort-level revenue. Cohort rows don't just exist — they're computed, not typed.
Role-based compensation by department, benefits load, 15% payroll tax, salary inflation and ramp-up productivity curves. Every hire costs what it actually costs.
Base, Optimistic and Conservative scenarios with monthly burn, net cash flow, running cash balance, runway months and the dynamic zero-cash date. Switch scenario in one cell.
LTV, CAC, LTV:CAC, Magic Number, Rule of 40 and Months to Recover CAC — pulled live from the underlying tabs, not retyped from last quarter's export.
No upsells, no "premium tier", no locked modules. The full 36-month engine is exactly what's listed below.
Practical outcomes — not adjectives.
Watch how a 12% lift in trial-to-paid, or a 1.5x lift in top-of-funnel traffic, moves MRR by month 18 — without rebuilding the model.
Move churn from 3.5% to 2.5% and see what a 1-point improvement is actually worth at month 36 — net of expansion, net of cohorts.
Add a senior AE in Q3 and the model shows the loaded cost, the productivity ramp, and the cash impact — including payroll tax and benefits.
Run Base, Optimistic and Conservative in the same file. The board sees the spread, not a single point estimate dressed up as confidence.
The dynamic zero-cash date updates as revenue and headcount assumptions move. No more "we have about a year-ish" answers.
LTV, CAC, LTV:CAC, Magic Number, Rule of 40 and CAC payback — all pulled live from the same underlying assumptions.
Hand the file over. The architecture, named ranges and audit trail make it reviewable — the kind of model a CFO would actually open.
One source of truth means the strategy meeting argues about the assumption, not which spreadsheet is right.
If you're the one the board calls when a number doesn't reconcile, this is for you.
