# zicula-sub-analytics-kit — free sample

Three real files from the full kit (20 files), each **trimmed to taste** —
enough to judge the quality, not enough to run your retention on:

- `cancel-survey-slice.md` — the how-to-use intro plus the first 4 of the
  12 cancellation reasons from `churn/cancel-survey-12.md`, verbatim: each
  reason with its follow-up question and the save-offer verdict (including
  the one where the right move is "no offer"). Reasons 5–12 and the
  implementation notes (what to log per cancel, count-vs-MRR review,
  when not to A/B test) are in the full kit only.
- `playbook-days-1-2.md` — Days 1–2 of `PLAYBOOK-14D.md`, complete and
  verbatim: the baseline day (export → run → reconcile-or-stop) and the
  leak-naming day. Days 3–14 — survey install, dunning, the calculator
  fork, the one-hypothesis fix, the digest habit, the decision review —
  are in the full kit only.
- `definitions-slice.md` — 3 of the 8 definitions from `mrr/DEFINITIONS.md`,
  verbatim: monthly amount, active subscription, and the new/reactivation/
  churned movement rules. Logo vs revenue churn, ARPU, naive LTV, cohort
  retention and the deliberate NOT-computed list are in the full kit only.

Everything shown is exactly how the full files read — same voice, same
verdicts, same "no black box" stance. What you are sampling is the writing
you would run your numbers on.

What the full kit adds (the other 17 files):

- `mrr/analyze_subscriptions.py` — the analyzer: your subscriptions CSV →
  MRR per currency, new/reactivation/churned/expansion/contraction, logo +
  revenue churn, ARPU, naive LTV, cohort retention; writes summary.md,
  metrics.json, snapshot.json and a SQLite DB. Python 3.8+, stdlib only.
- `mrr/mrr-waterfall.sql` — 7 ready-to-run queries: waterfall, quick ratio,
  biggest churned accounts, short-lived cohorts, retention matrix, currency
  exposure, annual-plan share.
- `calculator/calculator.html` — offline churn-cost calculator, 12-month
  baseline, EN/TH/DE/JA.
- `churn/dunning-sequence-5.md` — 5 payment-recovery emails (pre-dunning →
  win-back) with schedule and retry rules.
- `digest/digest-templates.md` — daily/weekly digest skeletons (EN/DE/JA).
- `benchmarks/` — your own 90-day benchmark tracker + why vendor "median
  churn" is marketing.
- `mappings/processor-csv-mapping.md` — Stripe / Paddle / Lemon Squeezy /
  Polar exports into one canonical CSV.
- `RECONCILIATION.md` — the 15-minute procedure + 8-item mismatch checklist
  (including the 100x-amount trap).
- `screenshots/` — rendered previews of the real files, so you know what you
  are opening before you open it.
- `PLAYBOOK-14D.md`, `README-buyer.md`, `LICENSE.txt` — single-founder
  commercial license.
