Feature Request: Voucher/Discount Code System

[rolland97]

Problem Description

Bookcars currently lacks a voucher/discount code system for promotional campaigns, customer retention, and marketing initiatives.

Proposed Solution

Implement a comprehensive voucher system with admin management interface and frontend integration.

Core Features

Voucher Types:

• Percentage discount (e.g., 20% off)
• Fixed amount discount (e.g., $50 off)

Admin Management:

• Create/edit/delete vouchers
• Set usage limitations (single-use, limited quantity)
• Configure validity periods (start/end dates)
• Basic usage tracking

Customer Experience:

• Voucher code input field during checkout
• Real-time validation and discount calculation
• Clear display of applied discounts in booking summary
• Error handling for invalid/expired codes

Technical Requirements:

• Database schema for voucher storage
• API endpoints for voucher validation and redemption
• Integration with existing payment flow (Stripe/PayPal)
• Admin dashboard interface additions

Use Cases

1. Promotional Campaigns: "SUMMER2024" for 15% off bookings
2. Customer Retention: Welcome discounts for new users

Additional Considerations

• Integration with existing user roles (Admin permissions)
• Prevent voucher stacking conflicts
