 6. **Country-Specific Logic Missing** - Pakistan payment methods not filtered
 7. **Site Industry Not Required** - Can create sites without industry, then can't add sectors
 8. **Broken Paid Signup Flow** - Imports non-existent `billing.Subscription`
-9. **Credits Not Single Source** - Account.credits, Plan.included_credits not synchronized
-10. **Invoice PDF Missing** - No pdf_file field, no proper PDF generation/download
-11. **No Billing Settings Section** - Collect minimal data in signup, need account settings for full billing info
 
 **Complexity Issues:**
-- Payment method filtering by region not properly implemented
+- 4 global payment methods + 1 country-specific = unnecessary complexity
 - Payment method config table exists but not used in signup flow
 - Manual payment instructions not shown to users
 - No clear workflow for payment confirmation after signup
-- Credits stored in multiple places instead of single source
-- Invoice PDF field missing, no download capability
-- Billing data collected but no account settings section for updates
