+## 🎯 QUICK WINS (Start with these)
+
+### 1. Run Migrations (5 min)
+```bash
+python manage.py makemigrations billing auth
+python manage.py migrate
+```
+
+### 2. Create Sample Data (5 min)
+Copy code from SESSION-SUMMARY-DEC-4-2025.md to create credit packages and payment configs.
+
+### 3. Create InvoiceService (30 min)
+Copy code from IMPLEMENTATION-GUIDE-DEC-4-2025.md, test invoice creation.
+
+### 4. Create Basic API (30 min)
+List invoices and credit packages endpoints.
+
+### 5. Create Account Settings Page (2 hours)
+Start with read-only view, add edit functionality later.
+
+**Total for Quick Wins:** ~4 hours
+**Result:** Migrations done, invoices working, basic page visible
+

+
+## 💡 TIPS
+
+1. **Start Small:** Don't try to implement everything at once. One service at a time.
+
+2. **Test As You Go:** After each service, test it in the Django shell before moving on.
+
+3. **Use Test Mode:** Always use Stripe test mode and PayPal sandbox initially.
+
+4. **Follow The Guide:** IMPLEMENTATION-GUIDE-DEC-4-2025.md has code templates for everything.
+
+5. **Check Examples:** Each task in the guide includes working code you can copy.
