NICHE — BUILD THE NICHE VERSION

You pay Baremetrics for turn-key historical MRR analytics and automated dunning without spending weeks engineering edge-case Stripe webhook processors. A simple dashboard displaying active subscriptions, simple MRR, and churn rates can be built in a weekend with an AI agent. Replicating Baremetrics completely fails when handling pro-rated billing shifts, failed payment retry logic (dunning), email delivery reliability, and multi-gateway normalization. If you only need clean MRR/LTV reporting on top of Stripe, build it yourself. If you rely on complex recovery campaigns and multi-billing systems, stick to Baremetrics.

Why this verdict

Building a basic SaaS subscription dashboard displaying MRR and active subscribers takes a few days with Stripe Webhooks. However, handling complex pro-rated upgrades, refunds, discounts, and automated credit card retry campaigns requires significant edge-case engineering.

The one-shot build prompt

Paste it into your agent of choice. Nothing else needed.

The one-shot build promptbuild it on Lovable
Build a Subscription Analytics & Dunning MVP using Next.js 14, Tailwind CSS, PostgreSQL, Prisma, and the Stripe API.

1. DATA MODEL:
- Customer: id, email, stripeCustomerId, createdAt.
- Subscription: id, customerId, status, stripeSubscriptionId, mrrCents, planId, currentPeriodStart, currentPeriodEnd, canceledAt.
- SubscriptionEvent: id, subscriptionId, type (NEW, EXPANSION, CONTRACTION, CHURN, REACTIVATION), mrrDeltaCents, timestamp.
- FailedPayment: id, customerId, stripeInvoiceId, amountCents, status (OPEN, RECOVERED, FAILED), retriesSent.

2. STRIPE WEBHOOK HANDLING:
- Implement an idempotent webhook endpoint for: `customer.subscription.created`, `customer.subscription.updated`, `customer.subscription.deleted`, and `invoice.payment_failed`.
- Calculate accurate mrrDeltaCents on plan upgrades, downgrades, and cancellations.
- Write code to handle prorations correctly without artificially spiking MRR.

3. ANALYTICS ENGINE:
- Build dashboard endpoints calculating: Total Active MRR, ARR, Net MRR Churn Rate, User Churn Rate, and Average Revenue Per User (ARPU).
- Create a Cohort Analysis endpoint displaying monthly user retention matrices based on signup month.

4. DUNNING AUTOMATION:
- When `invoice.payment_failed` occurs, log the event, generate a secure self-serve payment portal link via Stripe API, and trigger a simulated email event with a 3-step drip schedule (Day 1, Day 3, Day 7).

5. OUT OF SCOPE:
- Multi-currency conversions (assume USD).
- Integrations with non-Stripe gateways (Braintree, PayPal).
- Complex enterprise team access controls.

What you keep, what you lose

The honest trade of rebuilding it yourself.

What you can actually replace

  • ✓MRR and ARR metric calculation dashboards
  • ✓Customer churn and expansion tracking
  • ✓Cohort retention matrix calculation
  • ✓Subscription status lifecycle visualization
  • ✓Cancellation reason collection surveys

What you lose

  • ×Automated dunning email sequences with custom hosted credit card update forms
  • ×Turnkey industry benchmarking comparisons across SaaS and subscription brands

Why people still pay — the real moats

Moats

  • — Deep handling of historical edge cases across multi-gateway billing APIs
  • — Turnkey dunning automation engine with proven email recovery workflows
  • — battle-tested historical MRR waterfall calculation rules engine

Hard parts

  • — Reconstructing historical MRR state machine from asynchronous, out-of-order Stripe webhooks
  • — Handling prorations, mid-billing cycle plan shifts, and non-recurring discounts correctly in MRR calculations
  • — Maintaining idempotency when ingesting high volumes of payment processing events
  • — Normalizing multi-currency transactions against historical exchange rates
  • — Ensuring ultra-high email deliverability for automated payment failure notification emails
  • — Auditing metric discrepancies between custom database analytics and actual accounting statements
  • — Keeping webhook ingestion handlers updated with breaking changes in Stripe API versions
  • — Handling subscriber privacy requests under GDPR and CCPA compliant data deletion rules

FAQ

+Can I really replace Baremetrics with an AI-generated app?

PARTIALLY — DASHBOARDS ARE TRIVIAL BUT MRR WATERFALL MATH AND DUNNING ARE HARD. Building a basic SaaS subscription dashboard displaying MRR and active subscribers takes a few days with Stripe Webhooks. However, handling complex pro-rated upgrades, refunds, discounts, and automated credit card retry campaigns requires significant edge-case engineering. An MVP takes roughly 1 week; matching the product properly is closer to 3-6 months, due to complex historical MRR calculation edge cases and dunning retry logic.

+How long does it take to rebuild Baremetrics?

A usable internal version: 1 week. A version you would sell or bet a business on: 3-6 months, due to complex historical MRR calculation edge cases and dunning retry logic, mostly spent on reconstructing historical mrr state machine from asynchronous, out-of-order stripe webhooks.

+What do you actually lose by leaving Baremetrics?

Automated dunning email sequences with custom hosted credit card update forms Turnkey industry benchmarking comparisons across SaaS and subscription brands Multi-gateway consolidation (combining Stripe, Braintree, and App Store billing)

+Is it legal to build a Baremetrics alternative?

Building a competing product with your own code is normal competition. Copying their code, trademarks, brand assets or scraping their platform is not. Use the prompt to build your own implementation of common features.
