Micro-SaaS & Stripe Launcher

When to use this skill

• Building a new SaaS product or adding subscription features.
• Integrating Stripe Checkout or Webhooks.
• Planning a product launch.

1. Stripe Integration

• Checkout: Use Stripe Checkout (hosted page) for simplest PCI compliance.
• Webhooks: Always verify webhook signatures. Handle checkout.session.completed for provisioning access and customer.subscription.deleted for revocation.
• Idempotency: Ensure webhook handlers are idempotent (handle the same event twice without side effects).

2. Architecture (SaaS)

• Tenancy: Decide early: Single DB with tenant_id column (easiest) vs Database-per-tenant (complex).
• Onboarding: Create a friction-free onboarding flow. Minimizing steps to "Aha!" moment is critical.

3. Launch Checklist

• Legal: Terms of Service & Privacy Policy pages exist.
• Email: Transactional emails (Postmark/Resend) configured (SPF/DKIM/DMARC).
• Analytics: Basic tracking (PostHog/Plausible) to measure conversion.
