SaaS analytics looks like a dashboard but is mostly a data engine. The UI ships in two weeks. The Stripe ingestion, metric computation, edge cases, and quality assurance take 13–25 more.
## What this page covers
A factual breakdown of what it takes to build SaaS analytics correctly on Stripe — timeline, cost, and the structural problems that effort alone doesn't solve.
## The 10/90 split
SaaS analytics is roughly 10% dashboard, 90% data system.
- 10% UI shell (vibe-codable in 1–2 weeks): cards, charts, sparklines, filters, date pickers, layouts, theme tokens.
- 90% engine (13–25 additional weeks): Stripe ingestion (pagination, rate limits, webhooks), storage layer with reconciliation, 30+ correct metric equations with all edge cases, cross-validation against ChartMogul-style methodology, production hardening and sync recovery.
## Realistic timeline (15–27 weeks)
1. Foundation — Stripe API integration with auth, pagination, rate limiting, webhook receiver: 2–4 weeks
2. Data layer — schema, time-series indexing, refund/void/plan-change reconciliation: 1–2 weeks
3. Core metrics — MRR — 5-component decomposition (new, expansion, contraction, churn, reactivation): 2–3 weeks
4. Core metrics — Churn — logo vs revenue, voluntary vs involuntary, mid-cycle handling: 1–2 weeks
5. Core metrics — the other 28 — NRR, GRR, LTV, CAC payback, Quick Ratio, ARPA, ARPU, Magic Number, and so on: 2–4 weeks
6. Dashboard UI — cards, charts, sparklines, filters, layouts: 1–2 weeks
7. Quality assurance — cross-validate equations, edge case tests, audit: 2–3 weeks
8. Debugging marathon — customer-specific edge cases, methodology disputes: 3–5 weeks
9. Production hardening — monitoring, alerting, sync failure recovery, cost optimization: 1–2 weeks
After ship: 5–10 hours per week forever for Stripe API deprecations, edge cases in production, new metrics, and library updates.
## Cost (year one, approximate)
About $182K in engineering time, infrastructure, and ongoing maintenance for a single founder building this themselves. North Metric Pro is $79/mo ($948 year one).
## Why effort alone doesn't solve it
Four structural problems can't be vibe-coded:
- Benchmark intelligence: 1,400+ Stripe-verified SaaS companies, matched to your MRR tier and business category. You would need to convince 1,400 founders to share their Stripe data with you. North Metric already did.
- Dollar-impact quantification: every gap is priced. "Your churn is 2.4 points above the peer median — closing that gap is worth ~$1,800 MRR over 90 days." No internal dashboard produces this number.
- AI agents that act on context: ten AI agents work across three revenue domains. On Pro, three of them — Churn Radar (Protect), Payment Recovery (Recover), Upgrade Finder (Expand) — read your Stripe data daily and price every finding in dollars.
- The daily briefing (The North): every morning, what matters in order, priced in dollars. Not a dashboard to interpret — a list that names the next hour's highest-impact action.
## The buy alternative
Connect Stripe in three minutes. Free dashboard, 30+ metrics, drivers, period comparison — forever. Pro at $79/mo adds three AI agents with the 12.6% MRR guarantee: find at least 12.6% of MRR in 14 days or your first month is free.
