🚀 IMMEDIATE NEXT STEPS

Step 1: Apply Database Migrations (5 minutes)

cd /data/app/igny8/backend

# Create migrations
python manage.py makemigrations billing --name add_invoice_payment_models
python manage.py makemigrations auth --name add_billing_address_fields

# Review what will be created
python manage.py sqlmigrate billing <migration_number>
python manage.py sqlmigrate auth <migration_number>

# Apply migrations
python manage.py migrate billing
python manage.py migrate auth

# Verify tables created
python manage.py dbshell
\dt igny8_invoices
\dt igny8_payments
\dt igny8_credit_packages
\dt igny8_payment_method_config
\dt igny8_tenants  # Check new billing fields
\q

Step 2: Create Sample Data (10 minutes)

python manage.py shell

from igny8_core.business.billing.models import CreditPackage, PaymentMethodConfig

# Create credit packages
packages = [
    {"name": "Starter Pack", "slug": "starter", "credits": 500, "price": 9.00, "sort_order": 1},
    {"name": "Pro Pack", "slug": "pro", "credits": 2000, "price": 29.00, "discount_percentage": 10, "sort_order": 2, "is_featured": True},
    {"name": "Business Pack", "slug": "business", "credits": 5000, "price": 69.00, "discount_percentage": 15, "sort_order": 3},
    {"name": "Enterprise Pack", "slug": "enterprise", "credits": 20000, "price": 249.00, "discount_percentage": 20, "sort_order": 4},
]

for pkg in packages:
    CreditPackage.objects.create(**pkg, is_active=True)

# Configure payment methods for US
methods = [
    {"country_code": "US", "payment_method": "stripe", "display_name": "Credit/Debit Card", "sort_order": 1},
    {"country_code": "US", "payment_method": "paypal", "display_name": "PayPal", "sort_order": 2},
]

for method in methods:
    PaymentMethodConfig.objects.create(**method, is_enabled=True)

print("✅ Sample data created!")

Step 3: Start Implementing Services (Week 1)

Recommended Order:

1. InvoiceService (Simplest - Start here)

   • File: backend/igny8_core/business/billing/services/invoice_service.py
   • Refer to IMPLEMENTATION-GUIDE-DEC-4-2025.md for full code

2. PaymentService (Manual payments only)

   • File: backend/igny8_core/business/billing/services/payment_service.py
   • Start with manual payment creation and approval

3. Basic API Endpoints

   • File: backend/igny8_core/business/billing/views.py
   • Implement /v1/billing/invoices/ GET endpoint
   • Implement /v1/billing/credits/packages/ GET endpoint
