A payment bill query request initiated by a user through a third-party payment platform is obtained at a payment platform server. Whether a payment institution has generated a payment bill for the user is determined based on the payment bill query request, where the payment institution does not provide the third-party payment platform with bill generation information. If so, user information associated with the user is obtained by the payment platform server and based on the payment bill. Whether information for notification that the payment institution has generated the payment bill for the user has been pushed to the region that the user belongs to is determined. If not, the information for notification that the payment institution has generated a payment bill is pushed to each user associated with the third-party payment platform within the region that the user belongs to through an account of the third-party payment platform.
