+# Checkout Links Backoffice Implementation
+
+## Overview
+
+This implementation adds comprehensive backoffice functionality for managing checkout links, including the ability to browse all checkout links and restore deleted ones.
+
+## Features Implemented
+
+### 1. Backend Repository & Service Layer
+- **Restore Functionality**: Added `restore()` method to both repository and service layers
+- **Soft Delete Support**: Leverages existing soft deletion infrastructure (`deleted_at` field)
+- **Enhanced Sorting**: Added organization sorting support to checkout link repository
+
+### 2. Web Backoffice Module
+- **List Page**: `/backoffice/checkout-links/`
+  - Shows all active checkout links by default
+  - Option to include deleted checkout links with `include_deleted=true` parameter
+  - Search functionality by label, client secret, organization name/slug
+  - Sortable columns (created date, label, organization)
+  - Pagination support
+
+- **Detail Page**: `/backoffice/checkout-links/{id}`
+  - Shows comprehensive checkout link information
+  - Displays associated organization and products
+  - Shows restore button for deleted checkout links (when `deleted_at` is not null)
+
+- **Restore Action**: `/backoffice/checkout-links/{id}/restore` (POST)
+  - Restores soft-deleted checkout links
+  - Redirects back to detail page after successful restoration
+  - Includes proper error handling for invalid operations
+
+### 3. Navigation Integration
+- Added "Checkout Links" to the backoffice navigation menu
+- Properly integrated with existing navigation patterns
+
+### 4. Authentication & Authorization
+- Uses existing admin authentication system (`get_admin` dependency)
+- Requires admin user privileges to access the backoffice
+
+## Testing
+
+### Service Layer Tests
+- ✅ Test checkout link restoration functionality
+- ✅ Test restoring already active checkout links
+- ✅ All existing checkout link tests continue to pass
+
+### Integration Tests
+- ✅ Verify routes are properly registered
+- ✅ Verify navigation includes checkout links section
+- ✅ Verify main app mounts backoffice correctly
+
+### Manual Testing Notes
+The web backoffice endpoints require admin authentication which isn't easily testable in the automated test suite. Manual testing can be performed by:
+
+1. Starting the server with `uv run task api`
+2. Logging in as an admin user
+3. Visiting `/backoffice/checkout-links/` to test the functionality
+
+## Files Modified/Created
+
+### Modified Files
+- `server/polar/checkout_link/repository.py` - Added restore method, sorting support
+- `server/polar/checkout_link/service.py` - Added restore service method
+- `server/polar/checkout_link/sorting.py` - Added organization sort property
+- `server/polar/web_backoffice/__init__.py` - Added checkout links router
+- `server/polar/web_backoffice/navigation.py` - Added navigation item
+
+### New Files
+- `server/polar/web_backoffice/checkout_links/` - Complete backoffice module
+  - `__init__.py`
+  - `components.py` - Table components for checkout links
+  - `endpoints.py` - List, detail, and restore endpoints
+- `server/tests/web_backoffice/` - Test module
+  - `__init__.py`
+  - `test_checkout_links.py` - Comprehensive test suite
+
+## UI Components
+
+The implementation uses the existing backoffice UI framework:
+- Server-rendered HTML using tagflow
+- Consistent styling with existing backoffice pages
+- Reusable components (datatable, description lists, forms, buttons)
+- Responsive design matching the orders page pattern
+
+## Security & Audit Logging
+
+- Admin-only access through existing authentication system
+- Restore actions use the standard service layer for audit trail
+- Proper error handling and validation
+- No exposure of sensitive data in URLs or logs
+
+## Performance Considerations
+
+- Uses efficient database queries with proper joins and eager loading
+- Pagination implemented for large datasets
+- Includes deleted records only when explicitly requested
+- Proper indexing on `deleted_at` field (inherited from base model)
+
+## Future Enhancements
+
+The implementation provides a solid foundation that could be extended with:
+- Bulk restore operations
+- More detailed audit logs
+- Export functionality
+- Advanced filtering options
+- Real-time updates with websockets
+
+This implementation follows the existing codebase patterns and provides a seamless integration with the current backoffice system.
