Complex Features
- Service layer architecture: Business logic is encapsulated in dedicated service classes, keeping controllers thin and logic testable. Key services include PaymentService, OrderService, VendorService, and ProductService.
- Event-driven design: Uses Laravel events and listeners for decoupled communication — OrderPlaced triggers inventory updates, email notifications, vendor payouts, and analytics recording without hard coupling.
- Multi-vendor cart: Customers can add products from different vendors into a single cart. During checkout, the system splits the order into sub-orders per vendor, each with its own payment, shipping, and fulfillment workflow.
- Flexible coupon engine: Supports percentage and fixed discounts, usage limits per user/global, minimum order requirements, expiry dates, and vendor-specific or category-specific applicability.
- Role-based permission system: 8 user roles (Super Admin, Admin, Manager, Vendor, Vendor Staff, Support Staff, Inventory Staff, Finance Staff, Customer) with granular permissions managed through Laravel policies and gates.
- Payment gateway abstraction: Stripe and PayPal are integrated through a common PaymentInterface, allowing easy addition of new gateways without modifying checkout logic.
- Audit-ready activity logging: All critical operations — order status changes, payment events, vendor approvals — are logged with user, timestamp, IP, and payload for compliance and debugging.
