Abstract: Facilitating multi-user content personalization is described. Respective requests to personalize respective payments from respective payors to a payee are received from respective user devices executing a payment application. A customization user interface is presented to the respective payors from which the respective payors are able to customize respective screens to be presented to the payee, wherein a personalized payment functionality is selectively enabled for a first payor and disabled for a second payor. A first screen customized by the first payor and a second screen customized by the second payor are received from the respective user devices, and the screens are combined to generate combined output. An indication that the payee has opened the payment application on a user device is received, and, in response, the combined output is caused to be displayed via a user interface of the payment application executing on the payee's user device.
