A customer device generates an order for purchasing one or more goods or services from a merchant. A list of the purchased items is stored in a data structure designated as a tab. The list is routed to a merchant device. The customer device is carried by a user to the merchant. When the user reaches the merchant, the customer device or merchant device can receive a request to add an additional item to the list of purchased items. The tab remains open and modifiable until the customer device or merchant device receives an input to close it. Payment for the goods or services listed in the modified tab is processed upon closing of the tab.
