Commerce and booking systems live or die on correctness under load. We model contended resources — stock, rooms, seats — explicitly, and make the contended operation atomic so two requests can never oversell the same unit.
Payments are abstracted behind an idempotent gateway so you can add regional providers without touching booking logic, and reconciliation is automated rather than a monthly fire drill.
