Scoring Card

Dimension	Score	Rationale
Pain	4 / 5	Growth team can’t see billing data alongside engagement data
Revenue	4 / 5	Enables billing-aware sequences (trial expiry, failed payment, upgrade)
Build	3 / 5	Stripe webhook ingestion + event mapping + contact enrichment
Moat	3 / 5	Billing + engagement data in one graph is unique to integrated platforms

Classification

Foundation

Foundation — Infrastructure Dependency

Stripe Integration is a foundation module. It does not have its own UI for end users — it enriches the Contact Graph and Event Bus with billing data that powers sequences, segments, and analytics.

The Pain It Kills

The biggest blind spot in most growth stacks is billing data. Growth teams can see engagement but not revenue context:

1. Billing data is siloed in Stripe — the growth team can see who logged in today but not who is on a trial that expires tomorrow.
2. No failed payment recovery — when a payment fails, Stripe sends a generic dunning email. There’s no way to trigger an in-app nudge, a personal email from the founder, or a segment-targeted win-back sequence.
3. Manual webhook handling — teams that want billing events in their growth tools build custom webhook handlers. Each event type (payment_succeeded, subscription_canceled, invoice.payment_failed) requires custom code.
4. Can’t answer critical questions — “Which acquisition channel produces the highest-LTV customers?” requires joining Stripe data with analytics data manually.

Real scenarios:

• A SaaS product has a 14-day trial. They want to send a “Your trial expires in 3 days” email with a personalized discount for high-engagement trial users. Today: impossible without a custom cron job that queries both Stripe and the product database.
• A payment fails for a $200/mo customer. Stripe sends a generic email. Meanwhile, the growth team’s engagement data shows this user has been very active. A personal outreach could save the account, but nobody knows the payment failed until the subscription is canceled.
• A growth team wants to celebrate plan upgrades with an in-app confetti animation and a “Welcome to Pro!” email. Today: they’d need to poll the Stripe API or build a custom webhook handler.

What It Does

Stripe Integration syncs billing events and data into the GrowthOS Contact Graph and Event Bus:

Events synced:

• payment_succeeded — successful payment
• subscription_created — new subscription
• subscription_updated — plan change (upgrade/downgrade)
• subscription_canceled — cancellation
• invoice.payment_failed — failed payment
• customer.subscription.trial_will_end — trial expiring soon

Contact enrichment:

• plan — current Stripe plan/price ID
• mrr — monthly recurring revenue for this contact
• billing_status — active, trialing, past_due, canceled
• trial_end_date — when the trial expires
• subscription_start_date — when the subscription started
• payment_method — whether a payment method is on file

All Stripe events flow into the Event Bus, triggering segments, sequences, and analytics just like any other GrowthOS event.

Competition & What We Replace

Tool	Price	Limitation
Stripe webhooks (raw)	Free	Requires custom code for every event type. No contact enrichment.
ChartMogul	$100+/mo	Revenue analytics only. No lifecycle integration.
Baremetrics	$108+/mo	Revenue analytics only. No email/nudge triggers.
ProfitWell	Free (limited)	Analytics + dunning. No product engagement data.
GrowthOS Stripe Integration	Included	Billing events + contact enrichment + lifecycle triggers

---

Moat & Defensibility

The moat is billing + engagement in one data model:

• ChartMogul shows MRR trends. GrowthOS shows “users on the Pro plan who haven’t logged in for 7 days” — the kind of insight that prevents churn.
• Stripe webhooks give you raw events. GrowthOS gives you billing-aware segments: “trial users with high engagement score,” “paying users with failed payment,” “users who downgraded in the last 30 days.”
• The combination of billing status + engagement score + NPS data enables segments and sequences that no standalone tool can match.

Interoperability Advantage

Stripe Integration feeds billing data into the Contact Graph and Event Bus, enabling billing-aware segments and sequences across all modules.

---

What Ships

1. Stripe webhook ingestion — one-click Stripe Connect setup with automatic webhook endpoint registration
2. Event mapping — Stripe events automatically mapped to GrowthOS events
3. Contact enrichment — plan, MRR, billing status, trial dates stored on contact records
4. Billing-aware segments — pre-built segment templates: trial expiring, failed payment, churned, by plan tier
5. Pre-built sequence triggers — template sequences for trial expiry, failed payment recovery, upgrade celebration, cancellation win-back
6. Dashboard billing overview — per-contact billing status visible in the contact detail page

---

What Does NOT Ship

• Stripe billing management — GrowthOS does not create, modify, or cancel Stripe subscriptions. It is read-only.
• Invoice generation — no invoice creation or management.
• Payment processing — no checkout flows or payment forms.
• Revenue analytics dashboard — MRR charts, cohort revenue analysis, and financial reporting are not in scope. Use ChartMogul or Baremetrics for that.
• Non-Stripe payment providers — Paddle, Braintree, and other providers are not supported in P2.

---

Build vs Buy

Build (chosen)

• Stripe webhook API is well-documented and stable
• Event mapping to GrowthOS schema is straightforward
• Contact enrichment leverages existing Contact Graph infrastructure
• Pre-built segments and sequences are configuration, not code
• Estimated: 2 weeks

Buy

• ChartMogul/Baremetrics provide analytics but not lifecycle integration
• No off-the-shelf tool maps Stripe events into a growth platform’s event bus
• Building is faster and provides deeper integration
