Abstract: Systems and methods include onboarding services for retailer devices, guest user services for a user device, and operational services provided to the retailer devices and the guest user services for dispatching beverage orders. The onboarding services map retailer inventory of a retail establishment to a standardized product schema. Upon detecting that the user device is within a predetermined distance of the retailer device, the system generates and presents a user preference by performing a rationalized perato analysis on an order history associated with the user device. The order history and the preference are mapped to the standardized product schema. The user device receives a beverage order selection and, in response, the system generates a randomized order image to be presented at the user device and the retailer device. A transaction corresponding to the beverage order selection is executed at a point-of-sale (POS) system.
