What it means
Overbooking occurs when confirmed accommodation commitments cannot be fulfilled with the inventory available for the same dates. It may be obvious, such as two bookings for one apartment, or arise from a dependency: a combo is booked while one component is sold separately.
Why it matters
Early detection preserves response time and possible solutions. Hiding a reservation from the calendar does not solve the problem. Identify the physical conflict, retain its history and coordinate a solution consistent with the booking and channel terms.
An example in practice
A+B is confirmed from Friday to Monday. Another booking arrives for B from Saturday to Sunday. The listing IDs differ, but both reservations need B on Saturday night. Checking only duplicate IDs would miss the conflict.
A mistake to avoid
Deleting or moving a reservation without confirming an agreement with the guest can make matters worse. Conversely, two similar records may represent the same event imported twice: a technical duplicate is not necessarily a second real booking.
Put it into practice
- Confirm units, nights and original reservation references.
- Prevent further incompatible sales while investigating.
- Record the owner, communication, resolution and underlying cause.
A common question
Can maintenance also create an inventory conflict?
Yes. It can reduce usable capacity after a stay has been sold. Although this differs from a double sale, the team still needs to identify bookings without a suitable unit and resolve the exception clearly.
