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