# Stripe MRR Supabase Sync

> Sync Stripe MRR into Supabase

A production-grade pipeline that syncs Stripe payment data into Supabase via webhooks and nightly reconciliation, keeping the MRR card live and the payments table consistent. Built around idempotent webhooks (event.id as primary key), currency snapshotting, cohort retention, and a 3 AM reconciliation cron, it makes silent payment-data loss impossible.

## Use cases
- Inserting a payment row on every Stripe subscription or invoice webhook
- Rendering a live monthly-recurring-revenue card on an admin panel
- Running a nightly reconciliation diff between Stripe and the database
- Building cohort retention matrices by signup month and offset
- Snapshotting the exchange rate at payment time for accurate historical MRR
- Replaying failed webhooks safely with idempotency protection

## Benefits
- Prevent duplicate inserts and revenue inflation with event.id primary-key idempotency
- Catch webhook failures within 24 hours via an automated reconciliation alarm
- Keep historical MRR accurate even when exchange rates move using stored snapshots
- Render the revenue card in real time with Supabase subscriptions instead of polling

## What’s included
- Next.js Edge webhook handler with HMAC signature verify and idempotency check
- Supabase migration: events log, payments fields, MRR materialized view, cohort view
- Python reconciliation cron comparing Stripe charges against the database with alerts
- Real-time MRR card React component and a cohort-retention heatmap SQL query
- Webhook signature, idempotency constraint, and compliance discipline sections
- 12-item anti-pattern catalog plus a pre-production verification gate

## Who it’s for
Engineering and finance teams running Stripe-based subscriptions who need accurate, idempotent revenue data in their database and a live MRR view that never silently drifts.

## How it runs
Can you trust the MRR number on your dashboard? This pipeline makes it provable: idempotent webhook ingestion, frozen exchange-rate snapshots, a daily materialized view, realtime updates, and a nightly reconciliation that flags every missing or phantom row.
1. Receives each Stripe event on an edge handler: HMAC signature verified, then the event ID inserted as a primary key, so a replayed event is silently swallowed and never counted twice.
2. Writes the payment row with an exchange-rate snapshot frozen at payment date, so revenue history never drifts when the currency moves later.
3. Refreshes a materialized MRR view daily: active subscriptions summed, annual plans divided by 12, one-time purchases kept out of MRR as a separate KPI.
4. Streams the result to the dashboard over a realtime subscription: the MRR card updates the moment a payment lands, no polling.
5. Builds the cohort retention matrix (signup month by month offset), so churn patterns show up as a heatmap instead of an anecdote.
6. Runs a nightly reconciliation cron: Stripe's charge list for the last 24 hours diffed against the database; any gap fires a mail and an alert listing the missing or phantom rows.

## FAQ
### We run plain Postgres, not Supabase. How much of this ports over?
The core patterns port: event.id as primary key for idempotency, currency snapshotting at payment time, and the nightly Python reconciliation cron work on any Postgres. What assumes Supabase specifically is the migration SQL, the realtime-driven MRR card component, and the subscription-based rendering instead of polling.

### I already have a Stripe webhook handler writing to my database. Why is that not enough?
Because webhooks fail silently: a missed event means quietly wrong revenue numbers with no error anywhere. This pipeline adds the second leg, a 3 AM reconciliation cron that diffs Stripe charges against your table and alarms within 24 hours, plus event.id idempotency so replaying a failed webhook can never double-insert.

### Does it set up my Stripe payments or checkout flow?
No. It assumes payments already flow through Stripe and only solves what happens after: syncing that data into Supabase, keeping it consistent, and rendering a live MRR card. Building the checkout itself is the stripe-integration package's territory.
