EP3 — Standard Operating Procedures for Room Inventory Control
Introduction
Even the best technology fails without structured operating discipline.
SOPs ensure every department touches inventory in a controlled, predictable manner.
Core SOP Framework
- Assign a Room Inventory Controller (RIC)
Only one role has authority to:
- Open/close sales
- Adjust allocations
- Approve overrides
- PMS as the Only Source of Truth
No confirmation outside PMS is valid.
No Excel, no email, no verbal room holds. - Group Booking Confirmation Protocol
Step 1: Sales submits request in CRS
Step 2: RIC verifies and locks inventory
Step 3: System issues confirmation ID
Without confirmation ID → no booking exists.
- Daily Inventory Reconciliation
Every morning:
- PMS vs CRS vs Channel Manager
- Arrival vs room readiness
- Group pick-up verification
15 minutes daily prevents 90% of issues.
- Peak Season Zero Overbooking Rule
During high season:
- No manual overbooking
- No override without escalation
- Sister hotels used as alternatives
EP3 Conclusion
Technology controls data.
SOP controls people.
Both are required for zero overbooking.
