# Ticket Model States A [ticket](/data-models.md#ticket), depending on its state, represents either a customer order or a printed receipt. The ticket has two defined states: * **Opened**: Represents a customer order that has not been paid yet. * **Closed**: Once the ticket is printed on the receipt printer (or sent as e-mail receipt), it is marked as closed and becomes uneditable. You can determine whether a ticket is closed by checking the value of the `closeInfo` and `closeDate` properties. If the value both properties is `null`, the ticket is *open* and can be edited. If the values are not `null`, the ticket is *closed*, and the `closeInfo` value contains information about the closing procedure. This information includes details such as the [fiscal printer](/api-reference/fiscals.md) name, receipt sequence number and the unique receipt identifier provided by the tax authority (Finančná správa in Slovakia). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
