Techniques and arrangements for integrating predefined templates with open ticket functionality. For instance, a merchant device can identify a type of transaction between a merchant and a customer, select a ticket type for the transaction based on the type of transaction, and select a transaction flow based on the ticket type. The merchant device can then generate an open ticket for the transaction based on the ticket type, and associated transaction flow with the open ticket. Additionally, the merchant device can generate a visual representation of data associated with the open ticket, where a layout of the data within the visual representation is based on the type of transaction and the transaction flow, and present the visual representation to the merchant. In some examples, the type of transaction is identified using received input. In some examples, the type of transaction is identified based on a group associated with the customer.
