A method includes accessing at least one referral information entry. Each referral information entry associated with a referred user device is based on a referral from a referring partner application to a product. Each referral information entry includes an identifier for the referring partner application, a product identifier for the product, a time stamp of the referral, and a unique identifier associated with the referred user device. Sign-up information is received from a user device. The sign-up information includes a unique identifier of the user device, and a time of sign-up. The method includes mapping the sign-up information to the at least one referral information entry to determine whether the user device is one of the referred user devices. A determination whether the bounty requirements are met is made based on the mapped information and at least one predetermined business rule for referral bounties.
