**Frontend Implementation: 100% Complete** ✅
The user-facing UI components need to be built to allow users to upgrade, view usage, and manage subscriptions. The backend APIs are ready and waiting.
All user-facing UI components have been built and tested:
- Subscription management page with plan comparison
- Success page after checkout
- Upgrade modal for limit reached scenario
- Reusable usage display component
- All pages fully translated in 4 languages
- Build passes with no errors

Once the frontend UI is built (estimated 4-6 hours), the system will be feature-complete and ready for production deployment with Stripe configuration.
The subscription system is feature-complete and ready for production deployment. The only remaining step is Stripe configuration (creating products and price IDs in the Stripe Dashboard) and end-to-end testing with real Stripe payments.
