Add-on sold out below purchased count

An add-on’s available inventory subtracts both completed purchases and quantities reserved by in-progress registrations. It can therefore appear sold out even when its purchased count is below the inventory limit.

For example, an add-on with 215 total units and 211 purchased can have no available units if the remaining four are temporarily reserved. This is an example, not a diagnosis of a particular event.

Reservations normally expire after 15 minutes for simple events and 30 minutes for complex events; an institution’s configured timeout can differ. Waiting for an in-progress reservation to expire may free inventory without increasing the limit. Other ticket capacity, waitlist and event availability conditions still need to be checked.

Open Events → Events → select the event → Add-Ons to review the affected add-on. If it remains unavailable after expected reservations expire, give Support the event and add-on name so they can inspect actual purchases, reservations and capacity. Do not raise capacity without confirming that the additional inventory exists.
