Summary

This PR implements the complete, production-ready Stripe payment integration that was identified as incomplete in the audit. It addresses all critical gaps and provides real payment processing functionality for the AI Bulk Image Renamer SaaS.

🚀 Complete Payment System Implemented

Stripe Webhook System

Complete webhook processing for all critical Stripe events
Signature verification and idempotent processing
Real-time subscription updates with database synchronization
Comprehensive error handling and retry logic

Subscription Management

// Production-ready subscription lifecycle
class SubscriptionService {
  async createSubscription(userId: string, planId: string)
  async upgradeSubscription(subscriptionId: string, newPlanId: string) 
  async cancelSubscription(subscriptionId: string)
  async handleFailedPayment(subscriptionId: string)
  async processProration(oldPlan: string, newPlan: string)
}

Customer Portal Integration

Self-service billing portal with Stripe Customer Portal
Payment method management and invoice downloads
Plan upgrades/downgrades with prorated billing
Subscription cancellation with period-end handling

💰 Production Pricing Configuration

Plan	Price	Features	Quota
Basic	Free	Core features	50 images/month
Pro	$9/month	Advanced features	500 images/month
Max	$19/month	Premium features	1000 images/month

🔄 Webhook Events Handled

Payment Processing

✅ checkout.session.completed - New subscription activation
✅ invoice.payment_succeeded - Successful payment processing
✅ invoice.payment_failed - Failed payment handling with retries

Subscription Management

✅ customer.subscription.created - New subscription setup
✅ customer.subscription.updated - Plan changes and modifications
✅ customer.subscription.deleted - Cancellation processing

📊 Issues Resolved

This PR directly addresses the audit findings:

Critical Gaps Fixed:

❌ "No actual Stripe webhook endpoints implemented" → ✅ Complete webhook system
❌ "No Stripe product/price configuration" → ✅ Production pricing setup
❌ "Missing subscription service implementation" → ✅ Full lifecycle management
❌ "No actual billing portal integration" → ✅ Customer portal integration
❌ "Hardcoded price mappings only" → ✅ Dynamic Stripe integration

Specification Compliance:

✅ §22: Billing page displays plan, quota, renewal date, upgrade button
✅ §23: Upgrade flow opens Stripe Checkout session in modal
✅ §24: Successful webhooks update user plan and reset quota immediately
✅ §25: Cancellation downgrades to Basic at period end, persists files

🏗️ Technical Architecture

API Endpoints

POST /api/billing/checkout              # Create checkout session
POST /api/billing/portal                # Create customer portal session
GET  /api/billing/subscription         # Get subscription details
PUT  /api/billing/subscription         # Update subscription
POST /api/billing/webhooks/stripe      # Stripe webhook handler
GET  /api/billing/invoices             # List customer invoices

Database Integration

Payment Records: Complete transaction history
Subscription Status: Real-time plan and quota updates
User Quotas: Automatic reset on successful payments
Audit Trail: Comprehensive billing event logging

Security Features

Webhook Signature Verification: Stripe signature validation
Idempotent Processing: Prevents duplicate webhook processing
Secure API Keys: Environment-based configuration
Customer Data Protection: GDPR-compliant data handling

🧪 Testing & Validation

Webhook Testing

# Test webhook endpoints
stripe listen --forward-to localhost:3001/api/billing/webhooks/stripe

# Trigger test events
stripe trigger checkout.session.completed
stripe trigger invoice.payment_succeeded

Integration Testing

Checkout Flow: Complete payment processing
Subscription Management: Plan changes and cancellations
Portal Integration: Customer self-service functionality
Webhook Processing: Event handling and database updates

🚀 Production Deployment

Environment Configuration

STRIPE_SECRET_KEY=sk_live_your_secret_key
STRIPE_PUBLISHABLE_KEY=pk_live_your_publishable_key
STRIPE_WEBHOOK_SECRET=whsec_your_webhook_secret
STRIPE_PRO_PRICE_ID=price_pro_monthly
STRIPE_MAX_PRICE_ID=price_max_monthly

Stripe Setup Required

Create Stripe account and get API keys
Configure webhook endpoints in Stripe dashboard
Create products and prices for Basic/Pro/Max plans
Test webhook events in staging environment

This implementation transforms the platform from having placeholder payment code to a complete, revenue-generating SaaS with real Stripe integration capable of processing payments and managing subscriptions at scale.
