What it shows

  • Temporary holds lock inventory for 10-15 mins during checkout.
  • Payment confirmation transitions held rooms to booked instantly.
  • Post-checkout cleaning resets rooms back to available inventory.

The takeaway

Strict state transitions with TTLs eliminate double-booking in busy systems.
