Systems and techniques for detecting events involving users that occurred at an inventory location, and then using the events to determines states of the inventory location at various times. For instance, a system may generate event data representing first events that occur within an inventory location. The first events may include an associate performing a task, a customer removing an item, a customer returning an item, and/or so forth. The system may then use the event data to determine a state of the inventory location during a second event. In some examples, the state may include a tidy state or an untidy state. If the state includes a tidy state, then the system may generate a listing of items that includes at least one item associated with the second event. However, if the state includes an untidy state, then the system may further process the second event.
