## Outcome Delivered khoulefreres.com as an end-to-end booking product, connecting reservations, payments, coupon use, and customer notifications in one workflow. ## Context This was a founder-led product built on Laravel for KhouleFreres. ## Problem Bookings needed to carry correct pricing and payment state while customers received timely updates from reservation through confirmation. ## Constraints The booking, coupon, payment, and notification paths had to stay consistent without a separate reconciliation process. Historical performance and adoption metrics are not available for publication. ## Decisions and trade-offs Coupon validation and redemption were kept inside the booking flow so pricing and payment state remained aligned. Laravel observers were used for lifecycle notifications, favoring framework conventions over a separate notification orchestration layer. ## Implementation Built the booking product with integrated payments and coupon-based bookings. Laravel observers triggered email and SMS notifications at each stage of the booking lifecycle. ## Results The delivered flow kept reservation, coupon, payment, and notification state together and removed the need for manual customer follow-up described in the original scope. ## Takeaways For transactional booking systems, keep financial adjustments and customer communication attached to the same lifecycle that creates the reservation.
