Systems and methods for electronic payment using a mobile device for billing to a subscriber account. A purchaser (also referred to herein as a "subscriber") who has an account with a service provider for services unrelated to the purchase, engages a merchant in a transaction using a purchaser mobile device. The purchaser mobile device acquires purchase information to complete a purchase and unique purchaser identification information and communicates this information to a merchant mobile device. The merchant mobile device communicates the purchase information and the purchaser information along with unique merchant identification information to a service provider server. The service provider server interacts with the purchaser mobile device to authorize the purchase and bills a subscriber account associated with the purchaser mobile device upon a confirmation of the purchase.
